Easy maintenance and low maintenance cost; 5. It can grind slag and mixed cement with high moisture; 6. Guarantee the stable quality of cement and it is easy for adjusting quality; 7. Long lifetime; 8. Mill is designed simple and tight; 9. Mature and reliable technology
Working Principle
The vertical mill is mainly composed of powder concentrator, grinding roller device, grinding disc device, pressurizing device, reducer, motor, shell, etc. The separator is an efficient and energy-saving powder separation device. The grinding roller is a component used to roll and crush materials. The grinding disc is fixed on the output shaft of the reducer, which is the place where the grinding roller rolls materials. The pressurization device is a component that provides grinding pressure for the grinding roller and provides sufficient pressure to the grinding roller to crush materials. After being crushed by hammer crusher, the large material becomes smaller and is sent to the storage hopper by elevator, and evenly sent to the distribution board on the steering board through vibrating feeder and inclined feeding pipe. The grinding disc is driven by a motor through a reducer. The material falls from the feed opening onto the grinding plate. The material is driven to the edge of the disc by centrifugal force and crushed into fine powder by roller. Then, the hot air of the nozzle converts the fine powder into efficient classification. The qualified powder is brought to the powder collector through air for collection, and the unqualified powder is sent back for regrinding.
