Effect of ball size and powder loading on the milling ...

2013-12-1  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. This phenomenon is interpreted to be resulted from (1) the increased viscosity, and (2) the increased cushion effect

Critical rotation speed for ball-milling - ScienceDirect

1999-8-3  Rose and Sullivan showed critical rotation speed Nc, to reach the final stage, i.e., centrifugal motion: (1) N c = 1 2π 2g D−2r where D is the inner diameter of a jar and r is the radius of balls. All throughout, they used the critical rotation speed as the constant value for given conditions of ball-mill [5].

Variables in Ball Mill Operation Paul O. Abbe®

The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.
