### The effect of ball size on mill performance - ScienceDirect

The specific rates of breakage of particles in a tumbling ball mill are described by the equation Si = axαi(Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases. This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by xm = k1d2.

### Design, Construction and Performance Analysis of a 5 KgLaboratory .

Abstract- In this study, a 5 kg laboratory ball mill has been designed, constructed, and its performance analysed. This was achieved by using Bond's equation to calculate the specific and shaft powers required to drive the mill at the specified capacity, and also to size the mill. After the fabrication of the ball mill, grinding test.
