Problem is that for the Bond work index suggested by contractor, size of mill will be short, Motor and gear box for the mill also get short There is a Play of money in ball mill sizing What are the problems plant people faces if we will go with Ball Mill selected on the basis of work index 1536kWH/t

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

The Ball Mill Charge: Clean the Ball Mill and accessory equipment before starting Count and weigh the Balls by sizing group Record the results on the Ball Count and Charge Weight Determination form Determine a charge weight made up of exactly 285 steel Balls

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material
