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 sum of the power calculated for each of the separate compartments.
For Sepol Efficiency In Cement Mills
IntroductionConventionally multi-compartment ball mills are used in finish grinding of cement. However, they are relatively inefficient at size reduction and have high energy consumption, so it is increasingly common to find grinding technologies such as High Pressure Grinding Rolls HPGR, vertical mills and Horomill in cement plants.

Multiple Choice Questions on Mechanical Operations
2. Wear and tear in wet crushing is more than that in dry crushing of materials. 3. Size enlargement (opposite of size reduction) is not a mechanical operation. 4. A 'dust catcher' is simply an enlargement in a pipeline which permits the solids to settle down due to reduction in velocity of the dust laden gas. Correct.
