Step 2. Since the grinding was carried out in a wet overflow mill in closed circuit, the value of k should be taken as 350 ( Table 7.2 ). Substituting data into Equation (7.16), we get the replacement size of grinding balls as. d B = 25.4 6250 350 0.5 2.4 × 12.8 75 3.281 × 1.5 0.5 0.33 = 61 mm. Step 3.

Wet grinding mills also referred to as media mills are used to reduce particles in liquids. The mills make it possible to break down, what are known as agglomerates into their finer individual particles. This increases color development, gloss transparency, particle size distribution and can even increase chemical activity.

The vibration can be generated by springs, electromagnets, air cushions or unbalanced mass. These mills also have application in fine (45 microns) grinding. High-energy vibration mills can grind materials to surface areas of around 500m2/g, a degree of fineness, which is impossible in a conventional mill (Russell, 1989).

Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials). The production of fines is low and consequently a rod mill is the right machine when a steep particle size distribution curve is desired. A product with 80% minus 500 microns can be obtained in an economical manner.

Area of contact is partly related to severity of operation in that it considers the area of contact between the work and the wheel. When a wheel is applied to the work, the force applied is distributed over all the cutting points in the grind zone. The larger the area of contact, the lower the force per grain.
