摘要：破碎机在很多产业中都有着不可代替的作用，有了破碎机后能够在陶瓷，化工，建筑，园林，制造业等等行业中起着重大的作用，是在这些行业中必不可少的一项。因为每个物质都有每个物质自己独有的特性，而且每个物质之间的差异也是十分大的，在结构上也是各有不同，为了能够满足各种需求，破碎机的样式也是十分丰富，目前破碎机的种类有很多例如：环锤式破碎机、反击式破碎机、辊轮式破碎机、颚式破碎机、环锤式破碎机。破碎机的破碎比较小、破碎的效率十分低下、对于能源的损耗比较高，这些缺点会让破碎机在某些方面没有办法很好的适用。比如在造路中，因为石料对应于针片状的承受颗粒能力很差，如果含量过高，就会产生由于承受不住而产生的断裂从而影响路面的质量，容易发生危险，这就需要我们来改善破碎机，能够改良出能够更高效的完成破碎机了。反击式破碎机的功能比较容易符合我们的目标。反击氏具有破碎质量高、比例小，颗粒好、效率高、耗能低、方便维护等优点。目前反击氏破碎机正以极快的速度开始取代其他种类的破碎机。这正是能够高效完成破碎的完美设备。47336

Counterattack crusher support cabinet design PF - 1415
Abstract: the crusher has the effect that cannot replace in many industries, after a crusher can in ceramics, chemical industry, architecture, landscape, and so on the manufacturing industry plays a significant role, is an essential in these industries. Because each material each material has its own features, and the difference between each material is also very big, is also different in the structure, in order to meet the demand of various, the style of the crusher is also very rich, at present there are a lot of the kinds of crusher such as: jaw crusher, counterattack crusher, roller roller crusher, cone crusher, ring hammer crusher. The relatively small crusher broken, crushing efficiency is very low, for the loss of energy is higher, these weaknesses will make crusher apply in some ways there is no way to good. For instance in road building, because corresponding to the needle flake stone particles under ability is very poor, if the content is too high, can produce the result of the overwhelming fracture so as to affect the quality of the pavement, prone to danger, this needs us to improve the crusher, can improve the to perform more efficient crusher. Counterattack crusher function is easy to meet our target. Counter's crushing quality high, scale is small, good particles, high efficiency, low energy consumption, convenient maintenance, etc. At present's crusher is at an extremely rapid rate began to replace other kinds of crusher. It is able to efficiently complete the broken perfect equipment.

1.1引言
  反击式破碎机，历史悠久，最早可追溯到1850年代，湖北的破碎机已有很长的历史。随着社会的发展，以及对破碎技术的要求，颚式破碎机很难满足要求，然后，在颚式破碎机的基础上，设计了反击式破碎机。 PF-1415反击式破碎机支撑箱体的设计+CAD图纸:http://www.751com.cn/jixie/lunwen_49253.html
