I.Mining Grinding Mill Usage and Application
Grinding Mill is used to grind materials in the fields of construction, mining, metallurgy 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, coal, ceram, slag and so on (400 kinds of materials). The materials should have the hardness less than 9.3 in Mohs scale and humidity less than 6 percent. The granularity of the end products can be changed from 30 to 425 meshes.

II.Mining Grinding Mill Working Features
This grinding mill has the same working principle as Raymond Mill, but its grinding device is fixed with 1000 - 1500 kg pressure spring. When the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of Raymond mill given
