Grinding Mill Processing Technology

LM vertical grinding system is made of raw material feeding system, grinding system, drying system and final-products transportation system, etc. For special materials, the auxiliary system is optional, such as explosion protection system. The drying system include two types, the pulse dust filter open circle system (without hot air) and pulse dust filter open circle system (with hot air). Raw materials in the hopper are lifted by elevator and pass though air-lock device, enter into the grinding chamber. Ground by the LM grinding mill, powders are collected and transported to silo. The advantages of this system are that it has simple structure, low investment and operation cost. For there is no heat source, it is suit for grinding dry material, the moisture should below 4%.

Working Principle of Grinding Mill

Motor drives millstone-device through reducer and the hot air comes into the machine from the air inlet. When the materials are fed to the centre grinding plate, they move to the edge of grinding plate under the action of centrifugal force. Then the material are grinded by the grinding rollers when they pass through the grinding zone. Crushed materials continue to move to the edge of the grinding plate until taken away by the airstream. The big ones fall down and the process of grinding continues. The qualified ones pass through the separator and are gathered by the collector.If there are some irons or some other sundries, they will fall down from the grinding chamber under the action of gravity when they move to the edge of millstone device. Finally, the scraper will clear them from the grinding machine.
