how to calculate grinding rate of ball mill

InGrinding, selecting (calculate) the correct oroptimum ball sizethat allows for the best and optimum/ideal ortarget grind sizeto be achieved by yourball millis an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, theballused inball millsis oversize “just in case”.

Grate Discharge millswill not face this issue. C) This value represents the Volumetric Fractional Filling of the Voids in between theballsby the retained slurry in themill charge. As defined, this value should never exceed 100%, but in some cases – particularly inGrate Discharge Mills– it could be lower than 100%.

Dec 08, 2009· Re:how to estimatethewear rateforBall mill. Hey;Ball wearcan be measured by weighing an entire charge before and aftergrindinga known tonnage of materials. With newballssample of givensizecan be weighed before and aftergrindinga given tonnage and, assuming uniform wear per unit ofball surface, the total charge wear can be estimated.

Thepower calculatedon using equation 1, (Bond, 1961; Rowland and Kjos, 1978), relates to: 1)Rod milling– arod millwith a diameter of 2.44 meters, inside new liners,grinding wetin open circuit. 2)Ball milling– aball millwith a diameter of 2.44 meters, inside new liners,grinding wetin open circuit.

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

Thegrinding-product size, P, in a Bondball mill, which is given by the aperture size which passes 80% of thegrindingproduct as a function of the aperture size of the test screen P k, can be expressed by the formula P= P k K 2.

Improve The CrushingRate Of Ball Mill. Considering from thegrindingmedia, another method to achieve energy saving and consumption reducing is to accurate the diameter of steel balls, and make the steel balls with proper proportion and make thegrindingmedia has proper shape.
