CALCULATION OF THE POWER DRAW OF DRY ,

CALCULATION OF THE POWER DRAW OF DRY ,

Equation 1 is multiplied by the factor of 108 A multi-compartment ball mill consists of two or more grate discharge ball mills in seri The same equation is used to calculate the power that each ball mill compartment should draw The total power is the sum of the power ,

Ball Mill Design/Power Calculation

Ball Mill Design/Power Calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed .

How to Measure Grinding Efficiency

How to Measure Grinding Efficiency

The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills Figure 1 The first example is a comparison of two parallel mills from a daily operating report Mill size 503m x 61m (165′ x 20′ with a ID of 16′) This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power .
