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.

Read OnIn mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
