Edge effect is a condition widely observed in High Pressure Grinding Roll (HPGR) operations that gives rise to reduced comminution at the edges of the roll surfaces. This effect is caused by a reduction in the local crushing pressure at the edges of the rolls resulting from the sliding friction between the static cheek plates and HPGR feed …
Due to the rapid development of the modern industry, people have higher and higher requirements on the rolling speed and quality of steel. The performance of conventional cast-iron roll cannot supply production demands because it contains higher chrome-nickel elements. The high-speed steel W6Mo5Cr4V2 with high service life, red …
