Vibratory drum mills

Vibratory drum mills — represent a cylindrical or trough-shaped housing, about 80% of its volume loaded with grinding balls (sometimes grinding rods). The vibratory mill operates like a ball mill, but the grinding media inside it is in a swaying trough-shaped gutter suspended on a spring. The grinding efficiency depends on the gutter vibrations frequency and amplitude caused by rotation the eccentrically applied cargo.
