effect of speed in ball grinding milling

Factors Affecting Ball Mill Grinding Efficiency

The 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. As well, mills with different

Effect of ball size and powder loading on the milling

01-12-2013· As the rotation speed (rpm) increases, kinetic energy of the balls increases, which, in turn, shifts the optimum ball size toward a smaller value because the negative influence is alleviated. As the powder loading increases from 1 to 35 g at a given rotation speed (rpm) and ball size, the milling efficiency decreases monotonically.

Mill Speed Critical Speed Paul O. Abbe

Too low a speed and little energy is imparted on the product. Too fast and inefficient media movement (known as cataracting) will generate high impact but also greatly increase mill wear. Even faster speed will result in the media centrifuging inside the mill and virtually no milling or movement of

Ball mill Wikipedia

The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies.
