Open circuit grinding to a given surface area requires no more power than closed circuit grinding to the same surface area provided there is no objection to the natural top-sie. If top-sie must be limited in open circuit, power requirements rise drastically as allowable top-sie is reduced and particle sie distribution tends toward the finer sies.

The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of sie of the grinding product. Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given sie of grinding product, the value of the work index Wi, which is determined by experiments, is not known.

Ball Mill Ball Consumption Calculation

This problem is considered in this paper and some solutions are put forward. Experiments were made on copper ore, andesite and limestone, and it was found that the change of the mass passing a test screen G could be related to the aperture sie Pk of the screen by the formula GK1Pk. The grinding-product sie, P, in a Bond ball mill, which is given by the aperture sie which passes 80 of the grinding product as a function of the aperture sie of the test screen Pk, can be expressed by the formula PPkK2.
