机械毕业设计（论文）-超细破碎机的设计.doc

摘要
随着破碎机技术的不断发展,人们物料的入磨粒度大小的要求日益增高,这就要求现有市场上的破碎机能够高效率、高质量的对原材料进行加工。而入磨粒度大小是影响下一步工序的关键因素。同时在破碎加工过程中,由于入磨粒度的大小,也会对原材料的输出有影响。因此,去减小入磨粒度是破碎机生产中一道必不可少的工序。物料粉碎可增加物料比表面积可加快物料在参与反应中的反应速度;其次在加工大块矿石时也有十分重要意义;并未原料的下一步加工工作做准备或便于使用。现代工程需要越来越多的高纯超细粉碎,超细粉碎技术在高技术研究开发中将起着越来越重要的作用。本课题旨在利用现代的技术对超细破碎机的设计与研究。
目前国内生产的破碎设备主要分鄂式、立轴式、反击式和锤式等种类。大多数产品在针对具体行业时,一般能满足行业特定的要求。但超细破碎机确是今后的一个研究方向。目前国内的冲击式和锤式破碎机能将1000mm的大块物料,一次性粉碎至10-30mm以下。,即一台机器就能完成从粗碎到细碎及磨碎的整个工艺过程。
总之,近年来国内外对破碎机尤其是超细破碎机的研究依然比较热,主要针对解决减小入磨粒度提高原材料利用率等方面。据介绍目前世界上有约15%的电能消耗在粉碎作业中,而且逐年增加,加之目前能源短缺,急需不断改善粉碎研磨作业,如采用“多碎少磨”工艺特别是研制高效粉碎设备和改进现有研磨机械,对于达到优质、高产、低成本、低能耗具有十分重要意义。

Abstract
With the development of the technology of crusher, people of grinding material into the particle size of the rising demand, which requires the existing market crusher can high efficiency, high quality of raw materials for machining. And into the ground particle size is the key factor of affect the next step process. At the same time in crushing processing process, because of the size, particle size into the ground to the output of the raw materials have influence. Therefore, to reduce ground particle size is the production of a necessary crusher process. For material crushing can increase the material surface area can speed up the material in than in the reaction speed of response; Second in the processing of ore also have very important sense; Not the next step in the raw material processing prepare for work or easy to use. Modern engineering need more and more high purity superfine crushing, super fine crushing technology in high technology research and development will play a more and more important role. This project aims to use modern technology of ultrafine crusher design and research.
The current domestic production of broken equipment is mainly points the hubei type, vertical shaft type, fight back style and of hammer type categories. Most products in specific industry in gene
