Overflow discharge mills are used when a product with high specific surface

  • Ball Mills Mineral Processing & Metallurgy

    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. The discharge trunnion can be furnished with trommel screen.

  • 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 stone has allowed stone manufacturers to

  • Slurry flow in mills with TCPL — An efficient pulp lifter

    The GDM include autogenous (ag), semiautogenous (sag) and grate discharge ball mills. The purpose of the pulp lifters is simply to transport the slurry passing through the grate holes into the discharge trunnion. The performance analyses of conventional design of pulp lifter have shown that a large amount of slurry flows back from pulp lifter into the mill. The degree of slow-back depends on

  • Peripheral Discharge Ball Mills -Theory and Practice

    This will be discussed under capacity. Conditions Affecting Ball-Mill Capacity. Capacity of ball-mills depends upon the following factors: fineness of grinding, weight or volume of ball charge, hardness of material, size of grate openings, and size of balls, other factors remaining constant.
