Industrial Gypsum Powder Vertical Mill Vertical Roller Mill For Gypsum | 5-100tph Capacity

• Grinding Disc: A horizontally rotating circular disc structure where materials are crushed by rolling.
• Grinding Rollers: Usually 2-4 conical or cylindrical rollers, which press and crush materials through a hydraulic system.
• Classifier: A dynamic powder separator (located at the top of the mill) that separates qualified fine powder, while coarse powder returns to the grinding disc for re-grinding.
• Transmission System: The motor drives the reducer to rotate the grinding disc.
• Hot Air System (Optional): Introducing hot air can simultaneously complete grinding and drying (e.g., drying is required when the moisture content of desulfurized gypsum is high).

The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc for re-grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is ground together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

• Efficient and energy-saving: Adopting the principle of material bed grinding, the specific surface area of finely ground materials increases, and they come into full contact with hot gases, resulting in fast dehydration speed and low energy consumption.
• Good product quality: The particle size distribution is uniform, and the three-phase ratio of the product is stable, which can meet the quality requirements of gypsum powder in different application fields.
• The process flow is simple: It integrates functions such as grinding, dehydration, and drying. The process flow is short, the layout is compact, and it can reduce the footprint and equipment investment.
• Excellent environmental performance: Low noise, minimal dust, equipped with an efficient dust removal system, which can effectively reduce dust emissions and meet environmental requirements.
• High degree of automation: Stable and reliable operation, capable of remote monitoring and automated operation, reducing manual intervention and improving production efficiency.
