The purpose of the machine is 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 Moh's scale and humidity less than 6 percent. The granularity of the end products can be changed from 30 to 425 meshes.
It adopts a working principle similar to the Raymond mill. Its grinding assembly is equipped with high-pressure springs with a bearing capacity of 1000–1500 kg. During operation, under the combined action of high-pressure springs and centrifugal force, the grinding roller rolls tightly against the grinding ring. Its rolling pressure is 1.2 times higher than that of a Raymond mill under identical working conditions, and the output can be increased by 20%–300%. When the grinding roller and grinding ring suffer a certain degree of wear, adjusting the length of the high-pressure spring maintains constant grinding pressure between them, ensuring stable output and product fineness.
