How to Size a Ball Mill -Design Calculator & Formula. A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners).

### 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 you are designing for.

### How to design a Ball Mill Grinding & Classification

How to design a Ball Mill Grinding & Classification Circuits Metallurgist & Mineral Processing Engineer. E= 10 Wi (1/√P80- 1/√F80)E= Specific Energy, Wi= Work Index,P80= Output,F80= FeedAfter this we need to multiply certain factors such wet/dry Factor, Separation Factor, Dia. factor, Open/Closed Circuit Factor etc.. E= 10 Wi (1/√P80-

### Ball Mill Application and Design Paul O. Abbe

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

### Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

### Ball Mills an overview ScienceDirect Topics

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64.
