High-Efficiency Vertical Roller Mill for Calcite Calcium Carbonate

Processing calcite into high-value ground calcium carbonate (GCC) powder requires a grinding solution that balances high efficiency, product quality, and operational cost. Our HVM vertical roller mill is specifically engineered to meet the rigorous demands of the non-metallic mineral industry, offering a cost-effective and reliable turnkey solution for GCC production lines.

Ultra-fine GCC powder (80 mesh to 1250 mesh) manufactured by Hefei Hengcheng serves as an ideal filler and additive for high-growth industries:

Paints & Coatings: Enhance product whiteness and weather resistance.
Paper & Building Materials: Deliver high-quality, consistent filler performance.
Plastics & Rubber Industry: Boost material strength and cut production costs.
Chemicals & Pharmaceuticals: Applied in special high-purity scenarios.

Our vertical roller mill is available in a range of models to suit different production scales from small to medium-sized operations, making it perfect for small-to-medium enterprises.

Core Advantages
Energy Efficient: Our vertical mill consumes 30-40% less energy than traditional ball mills. This is a direct saving on your operational costs .

Integrated Design: It integrates crushing, drying, grinding, classifying, and conveying into one unit. This simplifies your plant layout and reduces investment in auxiliary equipment.

Precise Product Quality: The advanced dynamic classifier ensures a narrow particle size distribution and consistent product fineness, critical for meeting strict downstream customer requirements. The product can achieve a d97 of 4-45μm, meeting high-value market specs.

Reliable & Easy to Maintain: Designed for 24/7 operation with low downtime. The hydraulic roller system allows for easy adjustment and quick roller replacement.

How It Works:

The motor drives the grinding disc to rotate via a reducer. Raw materials fall onto the center of the grinding disc through the feed inlet, while hot air enters the mill from the air intake.

Under centrifugal force, materials move toward the edge of the grinding disc. As they pass through the annular grooves on the disc, they are crushed and pulverized by the grinding rollers.

The pulverized materials are lifted up by high-speed airflow at the air ring around the edge of the grinding disc. Coarse particles fall back onto the disc for re-grinding.

Materials carried by the airflow pass through the dynamic classifier. Driven by rotating rotors, coarse powder falls back to the grinding disc for secondary pulverization, while qualified fine powder is carried out of the mill by the airflow and collected by the powder collecting device as finished products.

Moist materials are dried during contact with hot gas to reach the required moisture content of the finished products.
