prediction of ball mill media wear in sag mills . We have prediction of ball mill media wear in sag mills Traditionally mill media wear rate is evaluated by measuring the media level in the mill or by removing media charge and weighing it after a certain number of hours As mentioned above the mill was stopped after 24 h one cycle with a total of 24 cycles for each ceramic ball type

The wear rate exponent for SAG milling was experimentally determined to be n = 2.8.Grinding Media & Lining Media Liner Wear Rate Modelling, · An equation given by Mortsell, for the rate of metal wear, is. where is the total weight of balls, Wt' is the wear per unit time, d is as before and K is a constant which generally fills ...

prediction of grinding media wear in sag mills. SAG mills grinding media includes some large and hard rocks, filled rate of 9% - 20% SAG mill grind ores through impact, attrition, abrasion forces In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills.

Mill Steel Charge Volume Calculation. We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill The % loading or change.

Nov 12, 2016 Grinding Media & Lining Media Liner Wear Rate Modelling & Prediction. The cost of replacement of the metal worn from the working surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance.

Mill (grinding) - Wikipedia SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in . Related items: Mortar and pestle, Expeller ...

Grinding Media Wear Rate Calculation in Ball Mill Apr 29, 2017 Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T

Ball Mill Media (kg/kWh) = 0.0944*Ai^0.299 Aidan Giblet and J. Seidel published a paper on the 2011 SAG conference (MEASURING, PREDICTING AND MANAGING GRINDING MEDIA WEAR) and they obtained Ball Mill Media (kg/kWh) = 0.0817x (Ai)0.498 the two equations are very similar.

Because SAG mills rely both on the ore itself as grinding media (to varying degrees) and on ore-dependent unit power requirements for milling to the transfer size, throughput in SAG circuits are variable. Relative to other comminution machines in the primary role.
