### Grinding Media Wear Rate Calculation in Ball Mill

In any mill the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is seen to be Kick s law.

### Ball Nose Milling Strategy GuideIn The Loupe

Ball Nose Milling Without a Tilt Angle. Ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry the manufacturing of turbine blades and fulfilling general part radius requirements.To properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life and part finish follow the 2-step process below (see Figure 1).

### Grinding control strategy on the conventional milling

milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped without any further water addition to the first ball mill. The ball mill discharges to a sump where water is

As such when the product is sticky rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30 of the power used in a ball mill.
