Get PriceThe following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.

Get PriceA 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), wind or water ().

Get PriceThe ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed. Blending of explosives is an example of an application for rubber balls.

Get PriceAssuming that balls in the grinding mill rotate at the same peripheral speed as the mill wall, the rotation speed of the balls was estimated to be 400 rpm. Hence, the rotation speed of 400 rpm was chosen to estimate the total corrosion current in oxygen atmosphere from the polarization curves.
