Pebble Mill Grinding. Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.
To mill or grind raw materials like sand, kaolin clay, feldspar and other materials in ball mill. Ball mill is a large container in which raw materials and water are mixed and ground into liquid, which will subsequently be sent to a spray dryer via high pressure pump. It is cylindrical in shape and is made of very thick steel sheet.
