PYB2100型标准弹簧圆锥破碎机的设计
摘要
当今社会在不断向前发展，原材料的需求也是与日俱增，然而富矿资源的储备是有限的，这就导致着矿石品位的日趋贫化。从目前我国的冶金行业的统计数据来看，铁矿石及锰矿石的平均品位在20%~30%之间。由于冶金行业对于炉料各方面的要求较高，所以绝大多数的原矿是需要破磨和选矿处理的。圆锥破碎机就此应运而生，作为金属矿山选矿厂的主要破碎设备，其具有生产效率高，破碎出来颗粒小且均匀等优点，可将直径350mm左右矿岩破碎至l0mm以下，以满足入磨粒度的需要。
国内圆锥破碎机的研究起步较晚，上世纪50年代，在原苏联弹簧圆锥破碎机的基础上仿制开发而成了自己的弹簧圆锥破碎机。该类型破碎机靠动锥单向挤压和弯曲研磨破碎物料，而产品粒度则依赖于排料口大小，存在的不足之处就是物料之间相互作用很小，几乎是没有选择性的破碎过程。
近些年来，随着科学技术的快速发展，最新研发的新型圆锥破碎机其可破碎的物料类型及种类正在不断扩大，而破碎出来的颗粒度也在不断减校大型高效、实用可靠、节能减排和自动化是目前圆锥破碎机的发展方向。
本文主要研究了PYB2100型标准弹簧圆锥破碎机，在熟悉其工作原理及结构特征的基础之上，对结构参数和工作参数进行了选择计算，确定了动力方案并对所设计的关键零部件进行了校核计算。

Abstract
As society advances, the increasing consumption of raw materials, leading to the depletion of high-grade ore resources growing, increasingly depleted ore grade. China Metallurgical to mine, for example, the average grade of 31% of iron ore, manganese ore 22%. Thevast majority of undressed ore broken grinding and milling needs to be dealtwith after the furnace charge. Circular cone Breakers production efficiency, small size and homogeneous Pai expected to be broken mine rock from 350mm to the different levels of particles lOmm, meet the skills needs of granularity,so Circular cone Breakers became the major equipment of Metal mines plants.
20th century the early 1950s, on the basis of the spring-loaded Breakers of former Soviet Union,developed its own domestic Breakers.The most basic design concepts of this Breakers is control products’ granularity by the size of the mouth. Broken materialway is by moving conewinding equipment and one-way squeeze role broken materials,weak interaction between materials, Broken processvirtually no selectivity.
And the recent development of new highly efficient circular cone Breakers broken expanding the scope of application of materials, broken products granularity small, broken remarkable results. Currently circular cone Breakers is toward large, efficient, reliable, energy conservation, consumption and automation direction.
This paper mainly studied the type PYB2100 standard spring cone crusher, on the basis of familiarwith itsworking principle and structure characteristics, selected and calculated its structural parameters andworking parameters, determined the motivation scheme and checked calculation of the key parts that designed.
