A laboratory ball mill is an indispensable tool when it comes to the rapid, reproducible pulverizing, milling or grinding of a large variety of materials. Depending on the configuration and choice of mill, samples can be soft, elastic or fibrous but also hard or brittle. RETSCH offers 11 different laboratory ball mill models (the largest
A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and
