Based on the standard procedure defined by Bond, the ball mill work index is determined by simulating a closed cycle dry grinding in a laboratory Bond ball mill until a stable circulating load of 250% is established (Bond, 1949, Bond, 1952, Bond, 1961). The ball mill work index is determined by Eq. (10). The recommendation is the ball mill ...
Ball consumption would, therefore, be ÷ = lbs. balls per KWH input to the mill. For the Pinto Valley concentrator ball consumption should, therefore, be x = pounds per ton. Ballmill liner consumption was again estimated from Copper Cities experience as pound per KWH of primary grinding energy.
Product Description. Ball mill balls are a type of ball used in ball mills, usually made of highhardness materials such as steel, ceramics, hard alloys, etc. Ball mill steel balls is an important part of the ball mill, its main function is to carry out the grinding operation in the ball mill, and the material is crushed into the required size.

The length of grinding time for each run is adjusted until the mass of the oversize fraction is consistently times greater than the undersize. Under those conditions, the Bond test is considered as a lockedcycle process as it mimics the steadystate grinding of a closedcircuit ball mill with a classifier performing at CL of 250%.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4 or 5in. balls are more commonly used for ballmill grinding.
