Investigation Of The Effects Of Chrome Ball Charge On

Apr 01 comparison of the rheogram demonstrated that slurry density and fines content affected slurry rheology significantly while the effect of the chrome ball charge being negligible statistical analysis showed the effects of mill throughput and cyclone efficiency on the grinding index a term describing the overall

Investigation Of The Effects Of Chrome Ball Charge On

Apr 01 the mim copper concentrator employed two parallel ball mills d l5 m 63 m in the secondary grinding circuit to treat the product of agsag mills each ball mill was closed by two 660 mmdiameter cyclones during the surveys with the agsag product and the ball mill discharge combined to feed the cyclones underflow of the cyclones was the

Ball Mill Charge

Ball size and ball grade is determined by the feed ore size and hardness plus the ph level of the slurry the ball charge is determined by the operator targeting the balance between grind and throughput the higher the ball charge the more aggressive the milling becomes with softer oxide ores lower ball charges are usual however the harder sulphides does need more media energies to meet the p80

How Do You Calculate Ball Charge In Ball Mill

Calculate ball mill grinding capacity 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

Fluid Mechanics Of Slurry Flow Through The Grinding Media

Dec 31 this may be the only numerical technique capable of tracking the slurry free surface as it fluctuates with the motion of the ball charge the result is a prediction of the slurry profile in both the radial and axial directions hence it leads to the detailed description of slurry mass and ball charge within the

Slurry Ball Mill Silica Sand Ball Mill Coal Ask Ball Mill

Effects of slurry pool volume on milling efficiency tangsathitkulchai hypothesised that for an overfilled mill see fig 1 a pool of slurry 1 forms at the base of the ball mill charge a fraction of the ball mass 2 is submerged in the slurry this fraction works against the stationary suspension of slurry causing a liquid drag on the interstitial particles around the shoulder of the media

Amit 135 Lesson 7 Ball Mills amp Circuits – Mining Mill

For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r
