Grinding Mills - Blogger

High-energy vibration mills can grind materials to surface areas of around 500m2/g, a degree of fineness, which is impossible in a conventional mill (Russell, 1989). Vibration mills are made with capacities up to 15t/h, although units of greater capacity than about 5t/h involve considerable engineering problems.
