Particles in the vertical shaft impact crusher absorb and dissipate collision energy in the impact breakage. The distribution of the collision energy determines the breakage rate of materials and breakage energy consumption of the entire system. In this paper, the gas-solid coupling method is used t …
Impact crushers are utilized in aggregates production, mining operations, as well as in recycling applications. Depending on the type of an impact crusher, they are known for either high reduction ratios or capabilities to produce precisely shaped, cubical end products. Impact crushers can be used in all different stages of size reduction from …
