Ultra fine vertical roller mill
CLUM series ultrafine vertical roller mill was produced by Shanghai Clirik Machinery Co., Ltd. Relying on 12 years of experience in the production of ultrafine powder and based on German and Taiwan ultrafine vertical mill technologies. The top technical team members were joined this project. Besides, high-quality wear-resistant parts are used to develop milling equipment which in a real sense marks the first secondary classifying technology in mainland China, having product fineness of 400-6000 mesh.
The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high effiency classsifer.The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.
Working Principle of Vertical Roller Mill
l) High efficiency
Features of ultra fine vertical mill
Under the same finished final size and the same motor power, the capacity of stone micronizer is twice as much as jet mill, mixing grinder and ball mill.
2)Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3)High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4) High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5)Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
