Reliable Gypsum Vertical Roller Mill Natural Gypsum Vertical Mill Superior Grinding Performance
Gypsum Vertical Roller Mill
The Gypsum Vertical Roller Mill has a wide range of applications, covering multiple dimensions such as raw material characteristics, industry applications, and finished product uses. The following provides detailed explanations from different perspectives:
1. Applicable types of raw materials
Gypsum
Including dihydrate gypsum (CaSO ₄ · 2H ₂ O), hard gypsum (CaSO ₄), etc., it can be directly ground into gypsum powder of different fineness.
Industrial by-product gypsum
Such as desulfurization gypsum (a byproduct of industrial waste gas treatment in power plants), phosphogypsum (a byproduct of phosphate fertilizer production), fluorogypsum, etc., can replace natural gypsum in production after treatment.
Gypsum ore and derivatives
Gypsum ore, gypsum blocks, gypsum waste residue, etc. can be efficiently processed into powder that meets the requirements through the integrated function of vertical grinding and drying.
2. Structural composition
Separators: are important components that ensure product fineness, consisting of a speed regulating motor, reducer, housing, air outlet, etc.
Grinding roller: The main component for rolling materials, consisting of roller sleeves, roller cores, shafts, bearings, etc.
Grinding disc: fixed on the output shaft of the reducer, the grinding disc has an annular groove, which is the rolling groove for grinding materials.
Pressure device: an important component that provides grinding pressure, consisting of a high-pressure oil station, hydraulic cylinder, rod, accumulator, etc.
Motor and reducer: The motor drives the grinding disc to rotate through the reducer, which plays a role in reducing speed and transmitting power.
3.【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.

4. Performance characteristics
(1) 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.
(2) 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.
(3) 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.
(4) Excellent environmental performance: low noise, minimal dust, equipped with an efficient dust removal system, which can effectively reduce dust emissions and meet environmental requirements.
(5) High degree of automation: stable and reliable operation, capable of remote monitoring and automated operation, reducing manual intervention and improving production efficiency.
