Using the data in Table 1, an example CSE calculation for a typical reverse fed ball mill circuit where 75 μs is the circuit (cyclone overflow) target P80 follows: 1. From the ball mill feed size distribution calculate the %+75 μ as: 100 – 19.3 = 80.7% +75 μ. 2. From the ball mill discharge size distribution calculate the %+75 μ as: 100

Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes. Toxic substances can be ground, as the cylinder is closed system. installation, operation and labour costs are low.

Size reduction increases as the number of rotations and time taken for ball milling increases. Meshes of larger aperture should be used in sieving to obtain a complete curve of particle size distribution. Some particles were lost when transferring them out of the ball milling, which results in lighter weight obtained after ball milling

I often buy the somewhat coarser and less expensive perchlorate and chlorate and then run them through my mill until they are the mesh size I want. It also allows for the addition of any anti-cake you might want to use. I see no problem with doing this with homemade chlorate. I STRONGLY recommend that you use a dedicated mill jar and media for doing this, and not trying to clean the jar and

Mill Speed. No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation.

On account of their size in relation to that of the bubbles, particles larger than 48 mesh generally have too great a tendency to drop out of the froth and escape in the tailing, while the lower limit is determined by the fact that grinding finer than 200
