  • A closer look at increasing HPGR efficiency through

    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

  • Fluid Flow and Pressure in the Grinding WheelWorkpiece

    A model is presented for flow of grinding fluid through the grinding zone. It was found that the flow rate through the contact zone between the wheel and the workpiece is a function of fluid pressure in the grinding zone, delivery flow rate, fluid density, and wheel velocity. An empirical coefficient of value less than 1 is introduced. The coefficient
