  • Converting a ball mill from overflow to grate discharge Converting a ball mill from overflow to grate discharge

    Jun 23, 2020 Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until

  • Ball Mills - Mineral Processing & Metallurgy Ball Mills - Mineral Processing & Metallurgy

    Feb 13, 2017 Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill

  • Difference Between Lattice Ball Mill and Overflow Ball Difference Between Lattice Ball Mill and Overflow Ball

    Aug 20, 2020 The main feature of the grid-type ball mill is forced ore discharge, so the production capacity is higher, but the product size is larger than that of the overflow-type ball mill. When the material of the overflow type ball mill is higher than the discharge port, it will automatically overflow, so the discharge particle size is finer, but the production capacity is low
