摘   要

     為了提高加工效率，本課題設計了一種出料粒度為15～20mm的立軸式破碎機，根據要求設計了錘擊部分和反擊部分。物料由進料口進入破碎腔，經過錘頭的沖擊、剪切、劈碎、折斷，實現物料的中碎；錘擊的物料沖擊到安裝在破碎腔內的反擊板上，又經過物料與反擊板、物料與物料的互相沖擊,從而實現了物料的細碎。本機融合了錘式破碎機、反擊式破碎機與立軸式破碎機的優點,降低了生料和熟料的入磨粒度，較好地達到了設計要求。
關鍵詞：破碎機；反擊板；錘頭

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
