锤片式粉碎机设计项目说明指导书

1、锤片式粉碎机设计摘要饲料粉碎在生产过程中是非常重要一种程序。本次设计锤片式粉碎机就是当前粉碎机中最为广泛一种，它原理是运用高速旋转锤片来击碎饲料，低速物料在初次与高速锤片发生激烈撞击后，被撞击拉入加速区，在此颗粒速度能在很短时间内被提高到接近锤片末端线速度，并随着锤片一起作圆周运动，而在全速区逐渐形成物料环流层，同步物料也得到进一步粉碎。它不但有通用性广、效率高、粉碎质量好长处，并且尚有操作维修以便、动力消耗低等长处。本次设计对粉碎机每个零件都做了很详细地计算，例如锤片安装、主轴计算及筛片选取和计算。力求设计粉碎机有便于拆卸、操作简便、度产量高等长处。我想对此后先进锤片式粉碎机设计以及推广、进一步理论研究起到了一定作用。核心词：粉碎、饲料、锤片式粉碎机HammertypecrusherdesignABSTRACT：Theshatteringofthefeedintheprocessofproductionisveryimportantforaprogram.Thedesignofhammertypecrusherisoneofthemostwidelyincurrentpulveri。
