1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

The operational controls are also reviewed for optimized mill operation. Every element of a closed circuit ball mill system is evaluated independently to assess its influence on the system. Figure 1 below is a typical example of inefficient grinding indicated by analysis of the longitudinal samples taken after a crash stop of the mill.

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.

12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
