Calcite Vertical Mill | High-Efficiency Calcite Grinding Mill for Mineral Processing

Maximize the Value of Every Gypsum Source

Our gypsum vertical mill is more than a grinder—it's a precision processing system engineered to transform diverse raw gypsum (including natural gypsum, desulfurized gypsum, and phosphogypsum) into high-value, consistent powder. It is the cornerstone of modern, profitable production lines for building gypsum, gypsum boards, and other advanced materials.

By seamlessly integrating grinding, drying, and classification in a single, efficient process, it unlocks significant value from both primary and byproduct gypsum, turning potential waste into revenue and ensuring superior end-product quality.

Four Stages of Intelligent, Integrated Processing

Experience a seamless workflow where efficiency is engineered into every stage, dramatically reducing energy consumption and operational complexity compared to traditional systems.

1. Precision Feeding & Distribution: Crushed gypsum is steadily metered and fed to the center of the rotating grinding disc, ensuring a stable and uniform material bed for optimal grinding.

2. Efficient Material-Bed Grinding: Hydraulically-controlled rollers exert precise pressure on the material layer, utilizing the efficient "material-bed grinding" principle to crush with minimal energy waste and wear.

3. Simultaneous Grinding & Drying: Hot air (from a dedicated furnace or cost-saving industrial waste heat) is introduced from the bottom, fluidizing the material and instantly evaporating moisture as grinding occurs.

4. Closed-Loop Classification: An integrated dynamic classifier ensures only powder of the specified fineness leaves the system. Oversized particles are instantly rejected and returned for re-grinding, guaranteeing a perfectly consistent final product.
