Vertical roller mill is an energy-saving mill equipment that combines mature vertical mill technology, successful experience of internationally renowned companies, and technological innovation and upgrading of Baichy Heavy Industry. It is a comprehensive large-scale grinding equipment that integrates crushing, grinding, powder selection, drying, and material transportation. It has many characteristics such as centralized process flow, small footprint, low investment, high efficiency, energy saving, and environmental protection. It can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals, and other industries, and focuses on the three major fields of non-metallic minerals, coal powder and slag.

Roller Mill
Finished product fineness: 80-425 mesh
Feed size: ≤65mm
Production capacity: 10-320t/h
Product features: It integrates multiple functions into one, making production safer and more reliable, and the production capacity more outstanding.
Vertical roller mill mainly consists of the roller assembly, disc assembly, hydraulic station, transmission arm assembly, powder selector, main reducer, motor, machine body, main reducer lubrication station, hydraulic station, PLC electric control cabinet, and other parts.
When working, the main motor drives the disc to rotate through the reducer, and hot air enters the vertical mill body from the air inlet. The material falls from the discharge port to the center of the disc and moves evenly from the center to the edge of the disc under the action of centrifugal force. When passing through the roller grinding area of the disc, the large pieces of material are directly crushed by the grinding roller, and the fine particles are squeezed to form a material bed for inter-particle crushing. The crushed material continues to move to the edge of the disc until it is taken away by the strong airflow at the wind ring, and the larger particles fall back to the disc to continue to be crushed. When the material in the airflow passes through the upper separator, the coarse particles return to the disc for grinding under the action of the rotor blades, and the qualified fine powder is discharged with the airflow, collected and discharged by the system's powder collector as the finished powder. When iron blocks and other debris mixed in the material move to the edge of the grinding disc with the material, they fall into the lower cavity of the mill due to their own weight and are scraped into the slag discharge port by the scraper plate installed at the bottom of the grinding disc and discharged out of the machine (commonly known as slag spitting).
1. It integrates crushing, drying, grinding, grading, and conveying in one, with a compact layout and small footprint.
2. The whole machine works under sealed and negative pressure, without dust spillage; it has a limit device to avoid destructive impact and vibration noise; the transmission system uses a planetary gear reducer with low noise.
3. The material stays in the vertical roller mill for a short time, reducing repeated grinding, and the product particle size and chemical composition can be better controlled, which is convenient for stabilizing product quality.
4. The grinding roller and the grinding disc are not in direct contact, and the iron content in the product is low, which effectively ensures the whiteness and purity of the material.
