摘   要

     为了提高加工效率，本课题设计了一种出料粒度为15～20mm的立轴式破碎机，根据要求设计了锤击部分和反击部分。物料由进料口进入破碎腔，经过锤头的冲击、剪切、劈碎、折断，实现物料的中碎；锤击的物料冲击到安装在破碎腔内的反击板上，又经过物料与反击板、物料与物料的互相冲击,从而实现了物料的细碎。本机融合了锤式破碎机、反击式破碎机与立轴式破碎机的优点,降低了生料和熟料的入磨粒度，较好地达到了设计要求。

The designe of Vertical spindle type breaker
Abstract: In order to enhance the processing efficiency, this topic has designed one kind of material granularity is 15 ~ 20mm vertical spindle type breaker, according to requested to design has hammered the part and the counter-attack part. The material by enters the broken cavity, after the hammer head impact, cuts, chops into pieces, breaks off, the realization material center is garrulous; Hammers the material attacks installs in the broken cavity on the counter-attack board, also passes through the material and the counter-attack board, the material and the material mutual impact, thus has realized the material fragmentation. This machine fused the hammer type breaker, the counter-attack type breaker and the vertical spindle type breaker merit, reduced the crude material and the chamotte enters rubs the granularity, has met the design requirements well.
Keywords: breaker; counter-attack board; hammer head
