Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal C3 is the correction factor for mill diameter and is given as; 3 = (3) However, it is important to note that C3 = vessel used in producing the ball mill was got from a
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill
Calculation Of Material Charge For A Ball Mill Ocgd3 . Woa1 Method For Estimating The Ball Charge In the present invention a method apparatus and computer program are presented with which the amount of balls among ore material contained in a grinding mill is estimated as a percentage by volume of the total volume of the mill preferably the invention relates to semiautogenous mills in

Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In todays global markets, expanding mining groups are trying
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). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to
#0183;#32;1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of
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
