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.

McKissic et al. observed a temperature of 50 °C after 1 h milling in a Spex mixer mill and Takacs and McHenry reported milling ball temperatures of 66 °C [ 12, 13 ]. Comparably higher temperatures can be reached in planetary ball mills (PBMs), where temperatures from 60 to 600 °C can be measured, depending on the type of PBM, the grinding

An exact estimate of a golf ball’s weight is supplied by USGA. Ball weights do not have to exceed 1 ounce according to the USGA. The total weight of these products is 620 ounces. 93 grams. Adding 46 grams to the figure equals 46 grams in less than one unit, which are easier to figure out without figures that make up an equation from fractions.

The energy transferred to the substrate from one ball during one collision ( Δ E b) is given by Eq. 4: Δ E b = K a ( E b − E S) = 1 2 K a m b ( v b 2 − v S 2) ( 4) K a reflects the elasticity of the impact in which K a = 1 for inelastic collisions, and K a = 0 for elastic collisions (no energy will be transferred).

As a result of this, output of the mill is consistently high and the fineness of the coal ground is uniformly maintained at more than 80% passing through 200 mesh sieves as desired. Since the wear is uniform, rollers can be used up to 80 mm wear, without drop in the mill efficiency, output and fineness.
