Stirred media mills in the mining industry: Material

Jun 01, 2020· Stirred media mills. Efficient grinding of fine and ultrafine particles requires small media to increase the surface area and the consequent collision frequency, but ball mills are fundamentally limited in the momentum that can be applied to such small beads by the force of gravity, which sets a practical lower limit in media size.
