DBGM Vertical Roller Mill Features
High Efficiency
Using material bed grinding technology, the grinding efficiency is much higher than that of traditional ball mills.
Energy saving
Low energy consumption, saving more than 30% energy compared with traditional ball mills.
Easy to maintain
Simple structure, easy replacement of grinding roller and grinding disc, small maintenance workload.
DBGM Vertical Roller Mill Features
- 1. Material Feeding: The material enters the crushing chamber through the feed port.
- 2. Extrusion and Grinding: The grinding roller rotates under high-pressure gas, squeezing and rubbing the material on the grinding disc into powder or particles.
- 3. High-Speed Rotor: The rotor inside the equipment rotates at high speed, generating strong centrifugal force.
- 4. Impact and Crushing: The material collides with the impact plate fixed on the inner wall, causing an impact and crushing effect.
- 5. Particle Size Control: The required particle size is controlled by adjusting the discharge port and rotor speed.
- 6. Recirculation Effect: Part of the crushed material enters the chamber again for further crushing until the desired particle size is achieved.
- 7. Automatic Protection: The system automatically shuts down in abnormal situations to ensure safety for both the equipment and operators.
- 8. Closed-Loop Circulation: The process involves feeding, crushing, screening, wind conveying, and finished product discharge, continuously crushing the material until the required particle size is reached.
