The purpose of the industrial mill machine is to mill materials in the fields of building materials, mining, metallurgies and chemical industry. The materials should be non-flammable and non-explosive. Examples of the materials are: quartz, feldspar, barite, fluorite, dolomite, garnet, carborundum, bauxite, zircon, marble, calcite, iron ore, rock phosphate and so on(400 kinds of materials). The materials should have the hardness less than 9.3 in Moh scale and humidity less than 6 percent. The granularity of the end products can be changed from 30 to 425 meshes (the minimum is 1000meshes).
