the ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm to product size in the range of thus determining the ball mill work index the work index calculations across a narrow size range are conducted using the appropriate laboratory work 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 overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the total charge filling level to
wet-grinding ball mill: wet grinding is mainly used in ore beneficiation wet means that we add water and form a slurry, and that slurry is going to occupy 50% of the ball mill volume. In a wet ball mil, approximately 15% water may form slurry which is a mixture between water and the crushed ore, sometimes also referred to as pulp.circulating load calculation formula. for example your ball mill is in closed circuit with a set of cyclones the grinding mill receives crushed ore feed the pulp densities around your cyclone are sampled and known over an our shift allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tonsday or tonshour this is solidsdensities based circulating load
