Vibration ball mill, also known as a vibrating ball mill or vibratory ball mill, is a kind of ball mill machine that uses the high-frequency vibration of the cylinder to make the grinding medium in the cylinder impact the material by inertial force.. Vibration ball mill is a new type of high-efficiency and energy-saving grinding equipment. It has obvious advantages over traditional rotary ball ... The design applied here is mainly a ball mill with an agitator, the movement of the agitator making the beads move and impact or friction the particles to be milled. Design using a loose reduction media can be found, mainly in long horizontal mills but other designs, more efficient are actually using a compact vertical bead bed, agitated.
