MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING
• Ball mill specific grinding rate • Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values: 1. The dry ore feed rate to the circuit (t/h). 2. The % fines in the circuit feed. 3. The % fines in the circuit product. Use this equation to solve for circuit ...
CALCULATION OF THE POWER DRAW OF DRY …
To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is
THE OPTIMAL BALL DIAMETER IN A MILL
consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; Katubilwa and Moys, 2009; Erdem and Ergun, 2009). 330 N. Magdalinovic et al. A great number of explorers were dealing with the questions of determining the maximal ball diameter depending on the material ...
