Low Wear Rate Vertical Cement Mill 330 - 380m² / Kg Specific Surface Area

cement vertical mill

Vertical mill is an ideal d, widely used in cement, electric power, metallurgy, chemical, non-metallic minerals and other industries. It integrates crushing, drying, grinding and grading and conveying. It has high production efficiency and can grind the bulk, granular and powder raw materials into the required powdery materials.

advantages

• High grinding efficiency: Advanced grinding principle saves up to 20% to 30% in power consumption compared to ball mills. As the moisture content increases, more and more electrical energy can be saved.
• Strong drying capacity: It can be dried by high-temperature exhaust gas in the kiln, and can dry and grind raw materials with water content up to 15%.
• The volume is small and the process flow is simple: crushing, drying, grinding, separating and conveying.
• Low noise and less dust: there is no direct contact between the grinding roller and the grinding disc. Therefore, metal impact is avoided, and the noise is 20 to 25 decibels lower than that of the ball mill. The vertical raw mill operates with a fully enclosed negative pressure so there is no dust during operation, which helps to keep the production environment clean.
• Low wear rate and low metal contamination: metal wear is only 5~10g / t.
• With a stable chemical composition and uniform particle size, the product is easy to calcine.

working principle

The motor drives the grinding disc to rotate through the reducer, and the material falls from the feeding opening to the center of the grinding disc, moves to the edge of the grinding disc under the action of centrifugal force and is crushed by the grinding roller, and the pulverized material overflows from the edge of the grinding disc and is simultaneously from the nozzle ring ( Wind Ring) The high-speed upward hot air flow is brought to the high-efficiency classifier integrated with the vertical mill. The coarse powder is sorted by the separator and returned to the grinding disc for re-grinding; the fine powder is ground with the airflow and is collected in the system. Collected in the dust device, that is, the product. The coarse-grained material that has not been taken up by the hot air flow and the accidentally entered metal parts fall from the wind ring, are scraped off by the scraping plate, and are fed again into the grinding mill by the externally circulating bucket lifter.
