The production High pressure suspension grinding mill of Shanghai Clirik Machinery Co., Ltd., is the first generation of high-pressure grinding mill products which is based on the Raymond Mill improvements, it not only increased the high-pressure spring to ensure the stable operation of the grinding mill equipment, but also improve the grinding fineness, and enhance the efficiency of the grinding mill. Therefore, the use of the appropriate internally developed equipment to the burning of coal mining equipment, not only can greatly improve the utilization rate of coal,they are still many aspects of energy saving, environmental protection, technology, philosophy has a huge advantage. A variety of other types grinding mill is also based on the works of Raymond Mill improvements, but in the process of research and development learn the more high pressure hanging roller mill performance.
