  • Types of Ball Mills Our Pastimes

    These ball mills are often called planetary ball mills. The rotating drums are not usually detachable -- the material is poured into the top and the cap is replaced like a kitchen blender. Like all ball mills the speed and ball size have an effect on how the vertical ball mill works. Cone milling is one of the most common methods of milling in the pharmaceutical food chemical and associated industries. They are typically used for size reduction and deagglomeration or delumping of powders and granules.. Generally used for reducing material to a particle size as low as 180µm (80 mesh) they produce less dust and heat than alternative forms of milling.
