Small Ball Mills for Sale - 911Metallurgist

APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies. The power the mill draws is a function of the weight of the ...
