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.

Experimental Study on the Grinding Rate Constant of a Ball Mill .

3 and have been widely investigated especially on ball mills. When a grinding rate is examined in terms of mate- rial balance, there are two basic functions: the selec- tion function, which indicates the fracture probability of a particle, and the breakage function, which shows the size distribution of fractured particle.

Cement mill - Wikipedia

A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Contents. [hide]. 1 History; 2 Materials ground; 3 Temperature control; 4 Ball.
