Grinding Media Wear Rate Calculation in Ball Mill 911 Metallurgist

Grinding Media Wear Rate Calculation in Ball Mill 911 Metallurgist

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

How Ball Mill Ore Feed Size Affects Tonnage Capacity 911 Metallurgist

How Ball Mill Ore Feed Size Affects Tonnage Capacity 911 Metallurgist

Hard ore Work Index 16 = 100,000/65,000 = kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

For example, for an 36′ × 17′ SAG Mill, with a power consumption of MW, operating at 73% solids, % balls charge and at 76% of the critical speed, with 50% of the feed in the size class −6″ +1″; it could be possible to increment in 2% the balls charge (to %), reducing the % −6″ +1″ to %, with no changes in the ...

Ball Mill Capacity and Power Consumption Relationship to Mill Speed

Ball Mill Capacity and Power Consumption Relationship to Mill Speed

The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D²)·f5 (πD c9 np/√D) = cs np As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.

How Steel Charge affects Ball Mill Power Draw Grinding ...

No, it is not normal to operate above 40 to 45% charge level. Unless the trunnion is very small or unless you are using a grate discharge ball mill, balls will not stay in the mill, and you will spend a lot on steel to add a small amount of power. Formulas given for mill power draw modelling are empirical, and fit around field data over the ...
