Size Reduction Materials are rarely found in the size range required, and it is often necessary either to decrease or to increase the particle size. E.g. when the starting material is too coarse, and possibly in the form of large rocks, and the final product needs to be a fine powder, the particle size will have to be progressively reduced in.

The biggest rollers do not necessarily give the best throughput, especially when budget is factored in. If the goal is to run creams or lotions at a decent-size volume, a three-roll mill of 50 mm diameter would be sufficient. For media, such as pastes, which may require a stronger machine, a 65 mm diameter three-roll mill would be suitable.
