Ball Mills
8.3.2.2 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1.5 times the shell diameter Figure 8.11 The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.

The physics of cricket
The force on the ball has to slow it down to a complete stop and then accelerate it back in the other direction all in the space of 0.001 seconds Suppose that a 0.16 kg cricket ball hits a bat at 100 km/hr and then comes off the bat at 100 km/hr in the reverse direction Imagine a car accelerating from 0 to 100 km/hr in 0.001 seconds.
