Which is the best of  limestone vertical roller mill manufacturers? Limestone has become an indispensable material for modern construction projects, affecting the implementation of various projects, the limestone is mainly composed of calcium carbonate, lime and limestone used in large quantities Building materials are important raw materials for many industries. Limestone is processed into stone and stone powder through limestone crushers and limestone mills and can be applied to related industries. Our country has abundant limestone resources. Our company's limestone mill has brought a gospel to the limestone investment processing industry. The limestone powder application area is extensive, which stimulates the development of limestone milling industry and brings limestone mill manufacturers Economic benefits and development space.

vertical roller mill

Raw limestone enters the feeding silo via a grab machine, and after measurement, which is conveyed by a conveyor belt into a screw feeding device and fed to a roller type vertical mill, and the material in the grinding wheel moves from the center to the edge under the action of the centrifugal force as the disc rotates. After the compaction, degassing, and grinding processes, the material is brought up by the hot air that enters from the air ring at the edge of the disc, and it is instantaneously dried. The finer particles are brought to the classifier for sorting, and the coarse powder is returned to the disc. Grinding. The fine powder is brought into the baghouse and the product is collected and gas-powdered. After the finished product is collected, it is transported into the finished product bulk warehouse, and the exhaust gas is discharged after being silenced by the fan. Part of the hard-to-grind large-grained materials (and iron tumors, iron slag) enter the outer circulation system through the slag discharge port at the wind ring, and after being de-ironed, they are fed into the grinding mill again by the elevator.
