Advanced Gypsum Vertical Mill Gypsum Powder Making Machine With Dynamic Classifier | 80-325 Mesh Adjustable
Core Advantages of Vertical Gypsum Mill
High Efficiency and Energy Saving
- The power consumption for grinding is 30%~50% lower than that of traditional ball mills, as the rolling principle achieves
higher energy utilization efficiency.
- Integrates drying, grinding, and powder selecting functions, reducing the number of equipment and floor space.
Stable Finished Product Quality
- The fineness of the finished product can be precisely controlled by adjusting the rotation speed of the classifier
(usually 80~325 meshes).
- Materials stay in the mill for a short time, avoiding over-grinding and ensuring the activity of gypsum (such as the
strength of β-hemihydrate gypsum).
Strong Adaptability
- Capable of processing desulfurized gypsum (with 10%~15% moisture), natural gypsum, phosphogypsum, etc.
- High-moisture materials can be dried simultaneously through the hot air system.
Environmental Protection and Low Noise
- The fully enclosed system reduces dust spillage, and the emission concentration is less than 30mg/m³ when equipped
with a dust collector.
- The operating noise is lower than 85dB, which is lower than that of ball mills.
【Working Principle】
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. 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.

Typical Application Scenarios
Production of Building Gypsum Powder Grind and calcine natural gypsum
or desulfurized gypsum into β-hemihydrate gypsum (building gypsum powder), which is used in gypsum boards, putty, etc.
Resource Utilization of Desulfurized Gypsum Desulfurized gypsum from power plants has high moisture content. The vertical mill
can simultaneously dry and grind it to produce raw materials for building materials.
Phosphogypsum Treatment Grind and modify phosphogypsum, a by-product of phosphochemical industry, for use as cement retarders
or subgrade materials.
