The effect of grinding conditions was studied by changing the solids feed rate, the feed slurry density, the weight of ball charge and the mill rotation speed. The optima of these variables in terms of energy consumption and production rate of fine fractions were determined individually for each tested ore.
Abstract Different ores containing soft minerals as the main components were ground in a continuously operating ball mill at laboratory scale. The effect of grinding conditions was studied by changing the solids feed rate, the feed slurry density, the weight of ball charge and the mill rotation speed.

Grinding mill is made of wear resistant steel ball, there are many factors influence the ball grinding productivity. Generally speaking, the same specification of steel balls’ density is of high productivity and low density is of small productivity. mining industry Now brief analyses the effects of ball density on the grinding.1.First is the material
Increasing pulp density in a certain condition, the viscosity of ore pulp will strengthen, making it easier to adhere to ball mills, thus enhance the mill productivity to improve the grinding outcome. But when the pulp density is too high, the ropy ore slurry will have buffer action on ball mills grinding operation. Higher feeding speed can
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill),
