  • Overflow VS Grate Discharge Ball or Mill Why Retrofit

    To illustrate the comparison of the grate discharge Ball Mill to an overflow type of mill we are showing on page 31 several actual case histories of installations where the performance of grate discharge mills versus overflow mills have been proven. In each such test, run for long periods of time, the ore characteristics and size of feed were maintained identical so that the tests could be

  • Grate Type Ball Mill With High Efficiency And Good Quality

    Ball-Rod Mills of the grate discharge type are made by adding the improved type of grates to a standard Ball-Rod Mill. These grates are bolted to the discharge head in much the same manner as the standard headliners. The grates are of alloy steel and are cast integral with the lifter bars which are essential to the efficient operation of this

  • Grate Ball Mill,Overflow Type Ball Mill,Ball Milling

    The grate and overflow type ball mills are the most universal equipment in the mineral plant. The grate type is usually used in the first segment of the two stages, or place of discharging the rough ore. Porcelain Lined Ball Mill. Peanut shells are byproducts of peanut. The effective utilization rate of peanut shells is very low, because they are burnt directly or are used to feed animals

  • What are the differences between ball mill and rod mill

    Grate discharge ball mill. Grate discharge ball mill can discharge material through sieve plate, with the advantage of the low height of the discharge port which can make the material pass quickly so tha t to avoid over-grinding of material. Under the same condition, it has a higher capacity and can save more energy than other types of mills; It is better to choose a grate discharge ball mill

  • 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. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of discharge flow mechanism. The experimental results are
