Continuously charging grinding balls will allow your mill to maintain a consistent power draft, charge volume, ore feed rate, or consumption average (kg/t). Our system effectively mitigates the number of variables in the control formula of your mill to optimise the performance of your operation.
Dec 08, 2009#0183;#32;Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated. More simply and quite adequate is to keep a record of material ground and of charge

by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the balls and media. U is the fraction of the voidage that is filled by slurry. 3 v is the volume fraction of solids in the slurry. Let VB be the volume of steel balls in the mill, VMed be the volume of autogenous media and VS the volume of slurry. VB
Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:

The fraction of the mill volume occupied by the mill charge can be estimated based on a ratio of the crosssectional areas. The crosssectional area of the mill charge (A C ) can be determined from: A#226;C = H#226;B / 6W (3H#226;B#226;2 + 4W#226;2)
