Small Ball Mills for SaleThe L/D ratios of ball mills range from slightly less than 1:1 to something greater than 2:1. The tube and compartment ball mills commonly used in the cement industry have L/D ratios :1 or more. The fraction of critical speed that the mill turns depends on the appliion, and most mills operate at around 75% of critical speed.
Introducing mechanochemistry | Feature | Chemistry WorldBoth compressive and shear forces are put on any molecules inside. Ball mills have been used commercially for a number of nonsynthetic purposes for over 100 years, and are now found anywhere where the controlled reduction of particle sizes is needed. They are ubiquitous in the mining, cement, chemical, pharmaceutical, wood and ceramics industries.
