Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor. The paper will propose possible operating

The F.C. Bond Ball Mill is a small universal laboratory mill used in calculating the grindability of all ores. GRINDABILITY IS THE NUMBER OF NET GRAMS OF SCREEN UNDERSIZE PRODUCED PER REVOLUTION. This Ball Mill can be used for units of time (hours, minutes) or it can be used for any number of revolutions, according to the type of grind desired.

bond f c crushing and grinding calculations Based on the above considerations for crushing and grinding the energy consumption for the clinker precrushing and ball milling can be estimated using the following Bond based model (9) W = W c + W m As precrushing product size P c is equal to the mill feed size F 80 then (10) W = A F 80 W i 10 P 80

The efficiency of the reduction machine may also influence the operating work index. For instance, a ball mill grinding an ore from 80 per cent-14 mesh to 80 per cent- 100 mesh will have a lower operating Wi value with 1.5-in. grinding balls than with oversize 3-in. balls.

The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load. The standard procedural outline of the test is stated in (Bond) 1961. The work index for a ball mill, Wi, is then calculated from the following equation.

Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.
