Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s The basic construction of a ball mill is a cylindrical container with journals at its axis The cylinder is filled with grinding media (ceramic or metallic balls.The sample feed size depends on the mill and can be as large as 8 mm If the feed size is larger than this then the sample must first undergo preliminary size reduction Milling – Jaw Crushers – Rotor Mills – Cutting Mills – Knife Mills – Mortar Grinders – Disc Mills – Mixer Mills – Planetary Ball Mills.The CryoMill is a laboratory ball mill specifically designed for this application It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process Thus the sample is embrittled and volatile components are preserved size reduction mixing homogenization cell.
