反击式破碎机用于硬岩破碎时的产品粒度特性

The characteristic of size of product of impact crusher for crushing hard rock

介绍了反击式破碎机用于硬岩破碎时其产品粒度随破碎机类型、板锤冲击速度、板锤磨损量、反击板开状及排料口完度等因素的变化关系,以期为破碎机的设计,使用及改进提拱有益的经验。

In the paper, the varidtions of product size of an impact crvsher for crushing bard rork are depended on the factors, such us, the type of a crusher, the blast velocity, wear and tear of blow bars, the shdpe of the impact plate plate and the width of discharge opening. All these, which are valuable to design, use and improve a crusher are described in the paper.
