随着我国对水电、高速公路、铁路和飞机场等大型基础、交通设施投入的增加，对高强度、立方体状的砂石料需求量越来越大。这些物料均属于难加工物料，硬度高、磨蚀性大，加工后针片状含量高。以前，一些企业采用常规破碎设备加工，不仅设备投资大，加工费用高，且产品粒形难于 As China’s hydropower, highways, railways and airports and other large-scale infrastructure, transport facilities increased investment in high-strength, cubic-shaped aggregate demand for more and more. These materials are difficult to process materials, high hardness, abrasive, needle-shaped high content after processing. In the past, some enterprises using conventional crushing equipment processing, not only equipment investment, processing costs are high, and the product grain difficult
