The Great Wall High-pressure Suspension Mill is used to grind materials in the fields ofconstruction, mining, metallurgy and chemical industry. The materials should benon-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 (400kinds of materials). The materials should have the hardness less than 9.3 inMoh's scale and humidity less than 6 percent. The granularity of the endproducts can be changed from 30 to 425 meshes.

Working Principle:
It has the same working principle as Raymond Mill, but its grinding deviceis fixed with 1000 - 1500 kg pressure springs. When the machine works, thegrinding 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 thanthat of Raymond mill given an identical condition and its output may increase20% to 30%;When the grinding roller and grinding ring reach a certain degree ofabrasion by adjusting the length of high-pressure springs to keep the constantgrinding pressure between grinding roller and grinding ring, stable output andfineness are guaranteed.
