SANDVIK ROCK PROCESSINGA GREAT RANGE OF SCREENS-and the people to support youSandvik offers you a wide range of quality screens. But that is not all. Many of our salespeople have a long experience with many types of screens and are well qualified to help youselect the right equipment for your plant. Sandvik has supplied customers with crushing &screening equipment for over half a century. Whether you need just a screen or a completeprocess solution, Sandvik can provide you with equipmentthat is easy to install and fully functioning from day one.Optimizing your screening processesA reliable, effi cient screen is not the only thing you need foroptimizing your screening process. An effi cient screen alsoneeds efficient wear protection, dust encapsulation andscreening media products. Thus satisfying increased require-ments for clean air, effi cient production and high up-time.Sandvik has a full range of screening media for vibrat-ing screens, in polyurethane and other rubber qualities.Sandvik also has a range of wear resistant rubber andpolyurethane products. Sandvik’s products meet the high-est quality standards, with both sheeting and wear plates.Advantages include long wear life, lower maintenance,reduced noise levels and improved working environment.So Sandvik can supply you with everything you need to opti-mize your screening process - and guarantee performance!Screens for all applicationsVibrating equipment commonly used for separating differ-ent grades of crushed minerals uses either stratification(screening with a vibrating bed) or free-fall screening.Conventional screens used in the aggregate industry havegreat versatility as regards separation limits and materialsize processed. They work on the stratification principle;the vibration of the machine sifts the material bed so that fi n-er material passes through the coarser material. This enables particles smaller than the meshof the screen to pass through it.Screens operating on the free-fall principle have been developed as an alternative to con-ventional screens. They are used successfully in both mobile and stationary plant. Sandvikhave further developed simple free-fall screening by building each deck in several sectionsand optimizing the inclination of the deck sections. F ree-fall screens can be built muchshorter and with smaller footprint than conventional screens of comparable capacities.Sometimes, non-abrasive, soft or sticky materials and materials with high moisture contentare best screened with equipment that does not rely on vibration as an operating principle.Sandvik offers roller screens that are ideal for careful screening of such materials.Take a closer look at the Sandvik range of machines and media. The people at Sandvik arethe people who can help you optimize your screening process!2Sandvik has developed screens and screening media to provide the best solution for your screening process....AND SCREENING MEDIA3Sandvik’s Master-F lo screen is one of the most common types of screen on the market.This sturdy, highly reliable screen comes in three different types and Sandvik can offer it in awide range of sizes.Master-Flo GSThe Master-F lo GS (Grizzly Screen) screens are recom-mended for installation between a primary feeder and aprimary crusher. Typical feed material is blasted rock, rippedrock or gravel with high fines content, often containingdiffi cult wet natural fi nes or clay. The Master-Flo GS screenshave a single grizzly or plate type of scalping deck with theoption of a second deck with woven wire. Master-F lo GSscreens immediately after a primary feeder gives moreeffective scalping than a primary feeder with a built-in grizzly.The stroke and speed of a Master-Flo GS remains constantwhile the feed rate is adjusted by varying the feeder speedproviding effi cient separation at all times.Master-Flo XSThe Master-Flo XS (Xtraheavy Screen) screens are built withextra heavy-duty applications in mind. They are circularmotion inclined screens with two or three decks, and canbe fi tted with wire mesh, polyurethane and rubber screen-ing media or steel plate on the top deck. The Master-Flo XSscreens are heavy and have more powerful motors anddrives than a regular circular motion screen. Master-Flo XSscreens have been designed for screening immediatelyafter a primary crushing operation, allowing a maximumfeed size of up to 400 mm.Master-Flo CSThe Master-Flo CS (Classifi cation Screen) screens are intended for heavy-duty, medium andfi ne screening applications. The screens are circular motion inclined screens in two, threeand four deck designs. Standard inclination is 18-20 degrees, depending on the size of themachine. The decks can be equipped with any kind of modern screening media of polyure-thane and rubber, wire mesh or steel plate.The Master-Flo CS range of screens is built for general quarrying applications and with aseparation range from 80 mm to 2 mm. The maximum feed size is generally limited to 150 mm,depending somewhat on the selected screening media. The Master-F lo CS screens canalso be used as splitter screens to divide flows within a plant and are frequently used forfinal screening of finished fractions. This range is also available with a successful waterspray system.MASTER-FLO™Wide offering of a highly reliable screen4Master-FloSandvik’s Master-Flo GS grizzly screens,Master-Flo XS xtraheavy screens andMaster-Flo CS classifi cation screens are theproduct of an over thirty years of continuousdevelopment of state-of-the art simulation.All critical components have been fi eld-tested with various applications. The resultshave been subject to careful analysis andcompared with our customers’ experienceand requirements.Sandvik Master-Flo screens have shownthemselves to be extremely reliable,economic, easy to use and suitable formost applications.*) Extra heavy duty with 2 x 30 kW driveThese Sandvik screen models are all heavy-duty machines, designed with a high carryingcapacity and a high G-force. The high adjustability and maintainability of the screens aresome of the main advantages. No extra space is required to maintain them, the mesh is easyto unbolt, and you can work on them in any type of environmental condition.Linel-FloThe horizontal Linel-F lo screen series has been purpose-designed for classification screening duties as well as forscalping ore ahead of a cone crusher in mining applica-tions. Linel-Flo screens are available with 1, 2 or 3 decksbut also with half decks as an option. Linel-F lo is an ex-cellent choice where the height is limited by surroundingfacilities, for the screening of small and short fractions andwhen heavy material is loaded on the screen. Linear orelliptical stroke improves the screening. Linel-F lo has amaximum feed size up to 300 mm and a separation rangefrom 100-1 mm.MSOThe MSO inclined screen has circular motion stroke in thecenter of the screen and elliptical stroke at the feed anddischarge end. The primary advantage of that is that itincreases the material speed at the feed end while at thesame time it decreases the material speed at the dischargeend. It is evident that the combined effect of these aspectswill result in a more accurate screening. Screens are avail-able with 1, 2 or 3 decks in the standard range of screensand half decks are available as an option. The MSO is aclassification screen just like the Linel-F lo screen. Themost signifi cant difference between these two units is thatthe MSO has only one vibrating mechanism. MSO has amaxmum feed size up to 300 mm and a separation of140-2 mm.Mechanism grizzlyThe MGS screens have been designed specifi cally for heavy scalping duties with the mainpurpose of removing fi nes from the feed before primary crushing. In conjunction with a facilityfor bypassing fi nes ahead of the crusher, MGS screens can be combined with Hydrostroke™feeders when heavy dump loads and high capacities are required.All MGS screens have their vibrating mechanism mounted under the feed pan. The doubleshaft mechanism generates an elliptical stroke, which consequently means better feeding aswell as a sustained material speed on the screen. MGS screens are available with 2, 3 and4 grizzly steps for the single deck models, depending on the size of the screen. The doubledeck models are equipped with three grizzly steps on the top deck and wire or rubbermedia on the bottom deck. The drive unit incorporates two motors with cardan shafts meaningthat neither gearbox nor gearwheels are necessary - the mechanism is self-synchronizing.The components of the mechanism are mainly the same as for the Linel-Flo and MSO screens.MGS has a maximum feed size up to 500 mm and a separation of up to 250 mm.LINEL-FLO, MSO & MGSMaintenance friendly, high-capacity screens6Linel-Flo, MSO and MGSAll dimensions are inside dimensions.Free-Flo™The main advantage of the Free-Flo screens is their ability to handle large loads of materialin comparison to their modest size. Free-Flo is often used instead of a slot sizer for removalof natural fi nes before crushers for separation of material for different crushing stages andfor final products of natural gravel, e.g., scalping, closedcircuit screening and fi nal product screening of gravel. Suit-able screening media are rubber, wire or plate elements forthe top deck, and wire mesh at the lower deck(s).The free-fall screening principle enables quick removalof large amounts of fi nes, using step deck inclination andeffective linear stroke almost perpendicular to the deck. Thefree-fall screening principle also gives low accuracy, as thevelocity of oversize particles is quite high, consequently eachparticle has a limited number of chances to pass a slot.The heavy-duty version of Free-Flo, FFx, is normally usedafter larger crushers, giving a maximum feed size of over150 mm. The three different frame models associatedwith the F ree-F lo range can be seen in the summary onthe right-hand page: F ree-F lo, S-version: Standard duty,F ree-F lo, H-version: Heavy-duty and F ree-F lo, X-version:Extra heavy-duty.Free-Classifi er™Free-Classifi ers share some of the same basic design prin-ciples of the F ree-F lo screen. The F ree-Classifier screenincorporates two different screening sections on each deck.This provides a free-fall action in the fi rst section and a moreaccurate stratifi cation in the second section. The result is acombination of the high capacity associated with free-fallscreening and the good separation accuracy known fromhorizontal screening. Another positive side effect is thecompactness of the machine.F ree-Classifiers are offered in three sizes, which are approximately 35 percent moreeffective than conventional screens in terms of a footprint area comparison. This fi gure will beeven greater with evaluation of a complete station, due to its lightweight design, consequentlygiving extremely low dynamic loads to the structure.FREE-FLO & FREE-CLASSIFIERFlexible free-fall screens8Free-fl o and Free-Classifi erThe free-fall screening principle ensures a free fl ow of material through all the decks. Free-Flo can be of much shorter construction and more compact than is the case with conventional screens.Free-Fall screening ensures that each stone can pass the screen early on. The cloth is always exposed to new material, without creating a bed of material.Free-Classifi er screens use free-fall screening without a bed on thefi rst part of each deck, but combine it with stratifi cation screening with a bed on the fi nal part. Therefore, Free-Classifi er screens combine quick fi nes removal and accurate sizing, making possible much shorter construction of the screen than with a conventional screen, but with the same width throughput capacity and screening accuracy.All dimensions are inside dimensions.Sandvik Roller screens are excellent for handling sticky material. All models are non-vibratingand very easy to dust and noise encapsulate.Roller GrizzlyThe Roller Grizzly (RSP) has been designed for scalping andscreening duties of low abrasive materials with an AbrasionIndex (Ai) below 0.03, such as limestone and coal. RollerGrizzly is compact and its ability to handle high capacitiesand moist material has been proven in many applications.Roller Grizzly is available for both primary and secondaryduties, depending on the maximum feed size.In order to achieve the best possible screening results it isimportant to spread the feed along the entire width of thescreen. The drop height of the material should be as lowas possible since the screen doesn’t sit on top of springs toabsorb the impact energy.Roller ScreensRoller Screens RSR, RSS and RSF have been primarily de-signed for coal and lignite screening. These screens aresuperior to vibrating equipment when the material is stickyand exhibits high moisture content. No vibration is trans-ferred to the support structure and the compact size andhigh capacity range make these screens highly competitive.Roller Screen RSR has been built for ROM (run of mine):coal screening. Roller Screen RSS is best used for second-ary applications: to screen washed coal. Roller Screen RSFfor 4-20 mm screening: screening in one dimension only.Roller Screen CrusherRoller Screen Crusher RSC has been purpose designed to remove impurities of commer-cial coal as well as to crush down existing coal lumps to acceptable sizes in coal-firedpower plants. Roller Screen Crusher comes complete with dust encapsulation, pre-screen,two crusher drums and after-screen. A pre-crusher might be necessary to put on top ofthe pre-screen if many lumps, such as frozen coal, are present. The crusher drums have areleasing mechanism to enable wood pieces, stones and other impurities to be rejected. Thesensitivity of the release mechanism is adjustable.ROLLER SCREENSYour choice for sticky material10Roller Grizzly, Roller Screen and Roller Screen CrusherScalping: 4-160 mm (i.e. limestone and coal)FLIP OVER TO FIND THE SCREEN SELECTION GUIDES C R E E N S E L E C T I O N G U I D EScreening duties:ScalpingScalping means that requirements for separation accuracy are low and feed rates high. Suitable machines for coarse scalping with separation > 100 mm are a vibrating grizzly feeder or an extra robust free-swinging, circular-motion screen with bar or pin grizzlies lined with heavy-duty rubber. Suitable machines for scalping of fi ner material with separation < 100 mm are a compact free-fall screen, a conventional Master-Flo or an MSO cir-cular motion screen with rubber elements. Closed-circuitClosed circuit screening normally means high capacities and “reasonable” accuracy require-ments. The separation size is often within 16 to 100 mm. Suitable machines are: a compact free-fall screen, a conventional Master-Flo or an MSO circular motion screen with rubber elements. Multiple decks are often used to reduce the bed thickness in applications with a large proportion of circulating material.Final fractioningThis duty requires a screen with good separation accuracy. Suitable machines for small separations <16 mm: a free-swinging linear/elliptical-motion Linel-Flo screen, a free fall Free-Classifi er screen or in some cases a circular-motion Master-F lo screen. We normally recommend wire or special rubber elements. When demands for separation accuracy are not too severe or if the frac-tions are longer, a free-swinging circular-motion screen can be selected. Polyurethane screening media is recommended for wet screening.。

第1页Screening Vibrating screensPrinciples--Vibrating screens save space and weight and operate on little power because the screening surface may be actuated by vibrating, gyrating or pulsating movement of small amplitude, but at frequencies that normally exceed 3,000/min.Selection of Proper Vibration Sereen--Be sure the screen supplier knows all details of the application. The centrifugal force factor, or combination of frequency of vibration (speed) and amplitude (throw), may affect performance of any vibrating screen. Also, a correct combination of slope and direction of mechanism rotation is vital for inclined screens. Usually, the larger the opening, the greater the amplitude needed for a screen.If the throw is too small, the material may clog or wedge in the openings. Increasing the throw beyond what is required to prevent blinding or plugging does not necessarily increase the life of the bearings and reduce screening efficiency. Increased rate of travel permits more tonnage to be passed over the screen per unit of time. For a given tonnage, a faster rate of travel results in a thinner bed of material and high screening efficiency.Maximum slope is reached when the material travels too fast for the fines to penetrate the ribbon of material and reach the apertures in the screen cloth. At this point an excessive amount of fine material passes over the screen with the oversize, resulting in poor efficiency.When an existing screen is to be used for an application other than that for which it was originally intended, check with the Supplier to see if any of the operating characteristics need modification and if the the screen is structurally suitable for the new application.The operator can get the correct vibrating screen by providing the supplier with the following information:∙Maximum tons per hour to be screened, including any circulating load or any surges in the feed rate.∙ A complete size consist or sieve analysis of the material or, if available, an estimated analysis.∙Type of material and weight per cubic foot in broken state.∙Separations desired on each deck.∙Surface moisture carried by the material if screening is to be dry or amount of water with feed if wet.∙Special operating requirements or conditions such as temperature, abrasiveness, corrosiveness or other physical characteristics of the feed,efficiency or product requirements which determine selection of screening surface, or installation problems which affect screen size selection or capacity. General Types --Vibrating screens may be divided into two main classes: mechanically-vibrated and electrially-vibrated. The former can be subdivided into classes based on how the vibration is produced--by eccentrics; by unbalanced weight; by cams or bumpers. They can also be subdivided as inclined and horizontal.Sizes --Vibrating screens are made in standard sizes of from 12 in. to 10 ft wide and from 2 1/2 ft to 28 ft long. Common practice dictates that the length of the screen should be 2.5 times the width for dry screening. For wet screening, wider and shorter screen is best. Screens for scalping ahead of primary crushers, operate at a slope of from 12 degrees to 18 degrees and have openings as large as 11-in. square. The eccentric throw for openings from 5 to 11 in. is usually 1/2 in.; for openings from 3 to 5 in. about 3/8 in.; and for smaller openings 1/4 in. The screening surface consists of a heavy cast desk, perforated steel with or without skid bars welded between the holes, rod deck, etc.The mechanical shaking screen comprises a rectangular frame, with perforated steel or wire cloth screening medium. It is usually inclined and suspended on loose rods or cables. These screens now are used mainly for special tasks of coarse screening, having given way to vibrating screens.Electrically-Heated Screens--Electrically heated screen cloth decks have afforded better screening and less dust. Modern or updated screening operations, now handling clays, limestone, potash, salts, phosphates and various hydroscopic materials, report minimum dust loss when equipped with heated screens. The controlling factor in this improvement is the electrically-heated screen doth deck. Any vibratory screen with fine opening (less than 1/2 in.) can be equipped with low volt-age-high amperage resistance heating.The principle of electric heating is based on the fact that small diameter wire of screen cloth (especially stainless steel) serves as a conductor, but offers resistance to a high-amperage current. This resistance causes heating of the wire when powerful transformer and specially designed bus bars connected to screen doth decks push up to 6,000 amps current into a circuit. The current is safe and shock-proof because voltage is low, ranging from approximately 1 1/2 to 16 volts. Workers can do their jobs around electrically-heated screens without special precautions.Heated screens are effective in preventing moisture content of material from causing buildup and blinding. The screen wire is kept at 100 degrees to 130 degrees F depending on character and tonnage of the material processed. This temperature is not high enough to weaken the wire cloth or screen structure, nor does it suffice to drive off moisture held in material. The warm wire stays dry, breaking the surface tension that otherwise would bind damp material to cold, damp metal. This differential orwarm, dry screen wire versus cold, damp material can be maintained economically through transformer control settings.With every opening in the heated screen mesh protected against blinding, there is no guesswork about what size particle will be delivered. A uniform, unvarying quality to meet tough specifications comes through day after day, no matter what the weather. (High humidity makes trouble with unheated screens.) Plants operating heated screens will have no trouble with excessive amounts of fine, dusty material that formerly sifted through reduced meshes on clogged screens.Service life of screen cloth is greatly increased when electric heating ends the punishment of old-fashioned cleaning methods, such as rough pounding or brushing. Blowtorch flames put too much heat in one spot and bouncing chains added to wear and tear. But, screens kept clean and open with electric heating reportedly are seldom mistreated and last up to eight times as long. Heated decks end the threat of pile ups and strains that can break the mesh.Economical operation of electric heating for screens requires one transformer for installations of up to three panels of screen cloth (maximum area 4- x 12-ft). Two transformers are used on longer decks. Any deck (top, center or bottom) can be heated. Electric heating is most desirable of all where a screen surface is hard to get at. Changing heated screens does not involve more unbolting than needed for ordinary screens.In specifying screens to deliver a uniform particle through heated mesh, the first thing to consider is weight per square foot of the wire cloth needed to set up appropriate resistance. Most calculations are based on square openings. Slotted openings must be identified as to width of clear opening, diameter of wire and number of wires per inch before weight per square foot can be found in any screen cloth manufacturer's catalog.Having determined the usable weight per square foot of screen cloth, the next step is to select the size of clear opening needed, making no allowance for reduction in this size as formerly was the case when material stuck to the wires. Heated wires will maintain the clear opening at all times, making it possible to screen finer without blinding.From a wire catalog, select a mesh weighing no more per square foot (can weigh less) than determined using the method above with the clear opening characteristics desired. This often turns out to be a more efficient screen because the wire diameter will be smaller and the percentage of the open area will be greater.For example, where a 1/8-in. clear opening was desired (but often blinded) on unheated screens, the wire diameter was 0.63 and the open area was 44 percent. The cloth weighed 1.43 lb/ft. 2. For a heated 3- x 12-ft screen, the weight must not exceed1.1 lb/ft2. Two options were found in cloth with 1/8-in. clear opening: wire diameter .054 weighing 1.09 lb/ft2providing 48.8 percent open area; and wire diameter .047 weighing 0.85 lb/ft2 with a 52.8 percent open area.Load conditions may make fine diameters of carbon steel wire inadequate. In such cases, stainless steel wire of larger diameter with greater load-carrying capacity will have the necessary resistance for good heating.Lighter wire with more open area yields higher tonnage and heated mesh stays open 100 percent. Two screen cloths connected in a series may be of different mesh sizes or clear openings, as long as they both weigh the same per ft2and do not exceed the weight allowed for that particular size of screen.With heated screens, major savings in pollution control are possible. Also moisture content of material is reportedly increased in a range of 5 to 8 percent. This moisture is added during or after crushing-grinding operations and holds down dust during transfer of material and passage over heated screens. Warm wire handles 5 to 8 percent moisture in stride. The cost of heating equipment and mist spraying reportedly is less than the cost of having bag towers and precipitators.振动筛的选择振动筛的选择原则:选择振动筛的原则是所选择的振动筛要节省空间、重量并且驱动的功率要小,因为筛选表面可以驱动并且发生振动。

2012届华北科技学院本科毕业设计外文翻译翻译题目:Hydrocyclone in the coal cleaning applications姓名:丁清珍学号: 2专业班级:矿物B081 院部:环境工程学院指导教师:张秀梅2012年6月20日Hydrocyclone in the coal cleaning applicationsTABLE 7-14. Effect of Geometry and Concentration of Feed Solids on throughput for a 1/6-in, diam hydro cyclone cleaning 1/4-inVarying the distance between the bottom of the vortex finder and the hydro cyclone cone bottom. For example, the washed coal ash can be reduced by decreasing the diameter of the vortex finder, decreasing the length of the vortex finder, or increasing the diameter of the underflow orifice. Increasing feed-Solids content increases the specific gravity of separation and, therefore, washed coal yield and ash, which indicates the importance of maintaining a constant feed-solids content to preserve washed coal quality.Capacity is influenced by cyclone geometry, i.e., the sizes of the overflow, underflow, and inlet openings, and by feed-solids content. The effects of these parameters is given in Table 7- 14.Increasing inlet pressure is a simple method of increasing capacity without changing hydro cyclone geometry, and washed yield and ash are not significantly affected. However, the penalty is increased pumping cost, and degradation of the coal.Flow sheetsSoon after the hydro cyclone was developed, it became evident that performance was inferior to nearly all other cleaning devices. Consequently, in an effort to improve performance, three two stage circuits, shown in Fig. 7~64, were developed. In the earliest two-stage circuit, called two-stage relearn or TSR, the refuse from a primary hydro cyclone is simply relearned in a secondary hydro cyclone, The overflows from the two hydro cyclones are recombined as the washed coal product, and the underflows from the secondary hydro clone contains the final refuse. In more recent installations, one of the products from the secondary hydro cyclone is recirculated to the feed of the primary hydro cyclone. In the two-stage overflow recirculation circuit, TSOR, the primary or first-stage hydro cyclone is adjusted to produce an acceptableclean coal and the secondary hydro cyclone is adjusted to produce a refuse essentially free of misplaced coal. The overflow from the secondary hydro cyclone, which contains the misplaced coal in the underflows of the primary hydro cyclone, is returned to the feed of the primary hydro cyclone for reprocessing. In the two-stage underflow recirculation circuit, TSUR, and the overflow is relearned in the secondary hydro cyclone. The underflow from the secondary hydro clone is recalculated to the feed of the primary hydro cyclone. The overflow from the secondary hydro cyclone contains the washed coal.Each of these circuits has advantages that depend upon the size and specific gravity compositions of the feed, as well as the required washed coal quality. The TSOR circuit is more effective in recovering washed coal whereas the TSUR circuit is more effective in rejecting heavy impurity. The TSR circuit is most effective when thespecific gravity of separation of the two hydro cyclones is similar. Conversely, the performance of TSOR and TSUR is improved by diverging the specific gravity of separation of the two cyclones. At the present time, the TSOR is the most common circuit. A variation of the TSR circuit has been proposed whereby underflow from the primary cyclone is relearned on a concentrating table rather than a secondary hydro cyclone.Some plants using jigs to clean the coarse coal utilize hydro cyclones to improve performance on the finer sizes. One method is to relearn the underflow of the washed coal screen, commonly the 1/4-in.material, with hydro cyclones. Another method is to screen the raw coal at about this size and clean the undersize with hydro cyclones.Hydro cyclones have been used ahead of dense-medium cyclones to remove some of the low specific gravity coal and thereby reduce the amount of material sent to the dense-medium plant. The hydro cyclones are adjusted to separate at a specific gravity of about 1.35 to 1.40. The advantage is that the capacity of the dense-medium cyclone plant can be smaller, thus reducing capital and operating costs.Hydro cyclone PerformanceAs mentioned previously, the quality of the washed coal and refuse products can be regulated by changing the diameters of the overflow and underflow orifices. However from a performance standpoint, a ratio of overflow diameter to underflow diameter in a range of about 1.7 to 2 gives the best results. Performance at lower ratios is inferior. Also, the solids content in the feed to primary and secondary hydro cyclones should range from 8 to 15 % (by weight). Outside this range, either above or below, performance is adversely affected.Separations obtained in a single hydro cyclone and two-stage circuits (TSR) are shown by the distribution curves in Fig. 7-65. The sharpness of separation of the two-stage circuit is significantly superior to that of a single hydro cyclone. Also, the sharpness of separation of the two-stage circuit is not nearly as sharp as the separations characteristic of a dense-medium cyclone. It follows then that hydro cyclones are not applicable for difficult-to-clean coal or separations at low specific gravity unless followed by a more effective relearning process. Also, they are not suitable for friable coal or where the refuse particles are platy. Table 7-15 gives detailed performance data for two-stage (TSR) hydro cyclones. These data indicate that in general the specific gravity of separation increases and the sharpness of separation decreases with decreasing particle size.Hydro cyclones may be especially applicable for cleaning -30-mesh (0.6- mm) coal if the coal is not amenable to flotation. However, the Majority of US coals are easily cleaned by flotation. But if the coal is not amenable to flotation because of a slime-coating problem or the coal is oxidized, then hydro cyclones may be a viable alternative. Also if fine pyrite is present in the feed, hydro cyclones are reported to be superior to flotation for lowering the sulfur content of the washed coal.The coarser particles of an easy-to-clean coal with a top size of 1/4 or 3/8 in.(6.3 or 9.5 mm) can be cleaned about as efficiently in a two-stage hydro cyclone circuit as on a concentrating table, but not as efficiently as in a feldspar jig. However, the concentrating table cleans the finer particles much more efficiently than the hydro cyclone. The distribution curves for a two-stage hydro cyclone circuit (TSR) and a concentrating table cleaning a 1/4-in (6.3mm*0) feed are shown in Fig. 7-66. A major advantage of hydro cyclones is that the space requirement is much less than for concentrating tables and jigs, but much more power and water are required. Spiralconcentrators are also used to clean-14-mesh (1.2-mm) coal.A relatively new separator, called the air-spared hydro cyclone, has been developed and can be used to clean opal. It is essentially a porous cylinder without the usual conical section. Feed enters tangentially at the top and spirals downward. Air is introduced through the porous cylinder, and the air bubbles and flotation reagents along with the vortex effect the separation. Coal particles attach to the rising air bubbles and exit the top through a vortex.水力旋流器在选煤方面的应用表7-14,给出了影响入料分选密度和粒度的处理量。
