The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by.

For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency . Output = Input x Efficiency In a ball mill circuit, the output can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies.

### Ball Milling Material Milling Jet Milling Aveka

Jan 31, 2015 Bigger balls helps in size reduction if the feed particles are bigger in size like chunks. If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling.Particle size reduction, screening and size analysis Schematic representation of the crushing mechanism in a ball mill In wet grinding, the surrounding medium is liquid, as opposed to dry grinding. Wet grinding should time required for the particles to settle a known distance in a fluid of known viscosity and density.
