摘 要

粉碎机械是应用机械力对固体物料进行粉碎作业，使之变为小块、细粒或粉末的机械。目前粉碎机在各生产、科研、医疗等行业被广泛应用。除了以上行业外还有矿产、涂料、冶金等行业，甚至科研单位都非常需要粉碎机。因此，如何设计出更符合各行各业生产需要的、先进的粉碎机是粉碎机生产单位的当务之急。

目前国内外市场出现了多种原理的粉碎机，尤其是锤片式和盘片式粉碎机在工农业生产中，已经得到广泛的应用，而且应用操作简单方便，但是这两种机型在性能上，锤片机应用广而应用在物料的粗加工上，盘片式机用于半精或精加工。为此，本设计将锤片式和盘片式优点性能结合，设计出了性能优良的的多功能粉碎机。本次毕业设计所做主要工作和结论如下：

1、了解了与粉碎机相关的知识；熟悉了粉碎机粉碎原理与分类，调查了国内外应用性能现状与市场前景，明确了多功能粉碎机的意义与基本原理。

2、通过查阅资料、市场调研确定了多功能粉碎机相关的总体方案。采取活动锤片和磨片结构；动、静片采用螺钉紧固方式安装。针对不同物料换取适当磨片或锤片。

3、独立完成了大轴、小齿轮轴和大齿轮的零件设计，大轴的加工工艺设计、带轮、磨片部件设计。

4、完成了详细的设计说明书及答辩材料。

ABSTRACT

Crushing machine is applied mechanical force to smash the operation of solid materials,

making it a small, fine or powder machinery. The current mill in the production, scientific

research, medical, and widely used. In addition to these trades, there are minerals, coatings,

metallurgy and other industries, and even scientific research units have a great need

for

shredders. Therefore, how to design more in line with the production needs of businesses,

advanced mill mill production unit is imperative.

Present a variety of domestic and international market principle grinder, in particular

hammer and disc mill in industrial and agricultural production, has been widely used, and

application of simple operation, the two models in performance on the application

of

hammer machine widely used in materials and roughing, the disc-type machine

for

semi-intensive or finishing. To this end, the design will hammer and disc-style performance

advantages combined with excellent performance designed multi-function mill. The main

work done by graduate design and conclusions are as follows:

1, to understand and mill-related knowledge; familiar with the principles of jet milling

and classification, investigating a domestic situation and market prospects of

application

performance, multi-function mill clear meaning and basic principles.

2, through access to information, market research to determine the

overall

multi-function mill-related programs. Activities undertaken hammer and grinding structure;

dynamic and static slice install with screw fastening. Appropriate for different materials for

grinding or hammer.

3, independently of the main shaft, pinion gear shaft and a large part design, processing

technology designed shaft, pulley, grinding components design.

4, completed a detailed design specification and defense materials.

Key words: multi-functional, grinder, hammer, grinding style, design
