  • Overflow VS Grate Discharge Ball or Mill Why Retrofit

    Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills

  • How a Grate Discharge Ball Mill Works

    Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to

  • Overflow Versus Grate Discharge Ball Mills: An

    A set of experimental test work has been carried out in a continuous pilot ball mill of 0.41m X 0.56 m (diameter X length) at different mill speeds, percent solids and discharge mechanism.

  • Converting a ball mill from overflow to grate discharge

    Jun 23, 2020· Conversion costs. The potential benefits of converting an overflow mill to a grate discharge will frequently far outweigh the downsides. In operations needing improved grinding circuit performance, the ability to fully utilise the available installed ball mill power will enable higher throughput, a finer grind, or a combination of the two, which will lead in turn to increased production and a
