文档介绍：摘要
粉碎是粮食加工生产过程中一道至关重要的工序,对于原材料的充分利用以及动植物的充分吸收起到关键作用,能够极大地提高饲料的利用率;同时,粉碎原料粒度的小对后续工序(如制粒等)的难易程度和成品质量都有着非常重要的影响,而且,粉碎粒度的大小直接影响着生产成本,在生产粉状配合饲料时,粉碎工序的电耗约为总电耗的50%~70%。粉碎粒度越小,越有利于动物消化吸收,也越有利于制粒,但同时电耗会相应增加,反之亦然。
粉碎过程的实质是通过输入能量使得物料的比表面积增大的过程。在此过程中,能量消耗在表面积增大、颗粒变形、摩擦、组织结构的变化方面。对于不同性质的原料,不同的粉碎方式,不同的输入能量,粉碎过程也不同。
我国每年粉碎加工总量达2亿多吨。饲料粉碎机作为饲料工业的主要装备,对饲料质量、饲料报酬、饲料加工成本的形成是一个重要因素。所以,恰当地掌握粉碎技术、选用适当的粉碎机型是饲料生产不可忽视的问题。
本课题设计的是一种经济节能型锤片粉碎机。本锤片粉碎机用于玉米等物料的破碎,具有产能高,节约能源,破碎效率高等特点。操作简便,维修方便,使用寿命长。

Abstract
Grinding is a very important procedure in food processing production process, to make full use of raw materials and the animals and plants to play a key role fully absorbed; the same time, crushed raw grain have a very significant impact on the degree of small follow-up processes (such as granulation, etc.), the ease and quality of finished products; Moreover, the granularity of the size of a direct impact on production costs in the production of powdered formula feed, grinding process power consumption is about the total power consumption of 50% to 70%. The smaller the granularity, the more conducive to animal digestion and absorption, the more conducive to granulation, but power consumption will increase accordingly, and vice versa.
The substance of the crushing process materials through the input energy makes the process of increasing the specific surface area. In this process, the energy consumption in the surface area increases, the particle deformation, friction, anizational structure change. Crushing the raw materials of different nature, different input energy, the process of pulverizing.
China smash the processing of a total of more than 200 million tons a year. The feed mill equipment, as the feed industry and feed quality, feed efficiency, feed processing cost is an important factor. Therefore, the proper grasp of grinding technology, selection of the appropriate type of shredder feed production can not be ignored.
The subject of design is an eco
