The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at critical speed. Result #2: This mill's ...

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.

maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent
