Gypsum is a monoclinic mineral whose main chemical component is calcium sulfate (CaSO4). Gypsum is a widely used industrial material and building material. Can be used for cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc. Gypsum board is an energy-saving and environmentally friendly product from the entire process of production, installation, and use. It can greatly reduce energy consumption and carbon dioxide emissions, and has become a new building material product that the country strongly encourages to use. Driven by a series of government bans on sticking and restricting stickiness, the application area of gypsum board is expanding. Previously, China's gypsum board had a sales growth rate of more than 30%, and it is expected that it will maintain a rapid growth of 10% -20% in the next ten years. At present, energy conservation and emission reduction has become China's basic national policy. This is not only the need to improve the quality of economic growth, but also the obligation of a responsible big country.
Many companies in the paper gypsum board industry do not implement national standards, their own standards are confusing, and gypsum powder is used instead of gypsum as a raw material to reduce costs. This new type of material with good market prospects has been promoted. A certain obstacle. For gypsum processing and reuse, the rigidity requirements of the gypsum vertical roller mill are relatively low. However, due to economic benefits, the stability and milling efficiency of the gypsum vertical roller mill are relatively high. Claim. Therefore, the gypsum vertical grinding mill requires that the gypsum vertical grinding mill has the highest possible grinding efficiency under the condition that the gypsum powder processing is stable and pure.
SBM heavy machine is China's large vertical grinding mill research and development and production export base, is an enterprise specializing in the production of micron powder grinding equipment. Including Raymond vertical grinding mill, vertical vertical grinding mill, high pressure suspension roller vertical grinding mill, European coarse grinding mill, well-known in the industry, it can be called a model of gypsum vertical grinding mill, gypsum vertical grinding mill The mill (European vertical roller mill) is used to process gypsum, which not only increases the output, but also has low power consumption. It is equipped with more advanced dust collectors and the dust emission concentration is completely lower than national environmental protection regulations, which greatly reduces production costs for enterprises.
Introduction to the working principle of gypsum vertical roller mill:
The raw slag of the gypsum vertical grinding mill enters the feeding bin through the grabber, and after feeding, it is fed into the helical feeding mill by the conveying belt into the screw feeding device. In the vertical roller mill, the gypsum material rotates with the grinding disc from the center under the action of centrifugal force. After moving to the edge, after the compaction, deaeration, and grinding processes, the material is taken up by the hot air entering from the air ring at the edge of the grinding disc and dried instantly. The finer particles are taken to the classifier for sorting, coarse powder Return to the grinding disc and grind. The qualified fine powder is taken into a bag dust collector, and the air powder is separated after the finished product is collected. After the finished product is collected, it is transported into the finished product bulk warehouse, and the exhaust gas is discharged after being silenced by the fan. Part of the hard-to-grind large-scale gypsum material enters the external circulation system through the slag discharge port at the wind ring, and is fed into the mill by the hoist again for grinding.
