Ball mills are used to grind ore from which gold can be extracted. The rotation of the ball mill helps mix the ore with water and other chemicals, which then causes the gold to break out of the ore.

The screen reports to the grinding circuit, which consists of two ball mills. The sizes of the passing particles (P80) for these mills are 4000 and 75 μ m, respectively. A cyclone between the ball mills with a cut particle size of 1000 μ m is considered. The combination of the ball mill with the cyclone yields a particle size of approximately ...
The method of ball distribution for a ball mill can be summarized as follows: 1. Take all the ore samples from a ball mill (usually take new ore and returned sand samples, then match the samples in proportion) for sieving analysis. Divide them into several particle sizes, such as 1812, 1210, 108, 86, etc. Then weigh each particle size, and ...
