Product Advantages

· Low Investment Cost

Integrates crushing, drying, grinding, classification, and conveying into one unit, with a compact layout and small footprint, suitable for outdoor installation, saving a large amount of investment cost.

· Easy Operation and Maintenance

The automatic control system can be remotely controlled, making operation simple; by servicing the hydraulic cylinder to flip the arm, roller sleeves and liners can be replaced, reducing downtime losses.

· Low Operating Cost

The grinding rollers directly crush the material on the grinding disc, reducing energy consumption; during operation, the rollers do not directly contact the disc, extending the service life of wear parts.

· High Drying Efficiency

Hot air introduced from outside enters the mill and directly contacts the powdered material multiple times inside, providing strong drying capability; the hot air temperature is adjustable.

· Stable Product Quality

Material stays in the mill for a short time, making it easy to monitor and control product particle size and chemical composition, reducing regrinding and stabilizing product quality.

· Environmentally Friendly and Clean

Low vibration, low noise, fully sealed system operating under negative pressure, no dust leakage, clean environment, meeting national environmental protection requirements.

Working Principle

The main motor drives the grinding disc through a reducer, while air enters the mill through the air inlet. Material falls onto the center of the grinding disc via the spiral feeder. Under centrifugal force, the material moves evenly from the center to the edge of the disc. When passing through the grinding roller track area on the disc, the material is crushed by the rollers; large pieces are directly crushed, and fine particles are compressed to form a material bed for inter-particle grinding. The crushed material continues moving to the edge of the disc until carried away by the strong airflow at the air ring. Larger particles fall back onto the disc for further grinding. Material in the airflow passes through the upper separator, where coarse particles are returned to the disc for grinding by the separator blades. Qualified fine powder exits the mill with the airflow and is collected by the system's dust collector, becoming the final product. Iron blocks and other impurities mixed with the material move to the edge of the disc but, due to their weight, cannot be blown away by the air and fall into the lower chamber of the mill, where scraper plates installed at the bottom of the disc scrape them into the slag discharge port for removal.

Vertical High-Pressure Roller Mill

The main motor drives the grinding disc to rotate through the reducer, while air enters the mill from the air inlet. The material falls onto the center of the grinding disc through the discharge port of the screw feeder. Under the action of centrifugal force, the material moves evenly from the center to the edge of the grinding disc. When passing through the grinding roller track area on the disc, it is crushed by the rollers. Large pieces of material are directly crushed, and fine particles are compressed to form a material bed for inter-particle grinding.
