Gypsum Grinding

Which Gypsum Grinding Mill is good?

The Gypsum Grinding Mill is our company’s many years of experience in the production of various mills. Based on the Gypsum Grinding Mill, we have extensively absorbed the ultrafine grinding theory at home and abroad, and designed and developed advanced grinding equipment. It is a professional equipment for ultra-fine powder industry that completes ultra-fine powder grinding, grading and conveying in one time. It can be widely used in chemical, metallurgical and non-metallic mineral industries. It can be used to grind the Mohs hardness below 5, the density below 3.2, the compressive strength below 150Mpa, the non-flammable and explosive minerals, the non-corrosive brittle material granular and the powdery raw materials (325~2500 mesh). ) Ultrafine powder. Generally used for the following materials: calcium carbonate, calcite, barium sulfate, talc, wollastonite, pyrophyllite, dolomite, graphite, kaolin, limestone and the like.

Structural principle

The Gypsum Grinding Mill is mainly composed of an electric motor, a reducer, a grinding roller device, a grinding disc device, a pressurizing device, a classifier, a body, a petrol station, a host PLC electronic control system and the like. The main motor drives the grinding disc to rotate through the reducer, and the wind enters the Huainan cement clinker vertical mill body from the air inlet. The material falls through the feeding end of the screw feeder in the center of the grinding disc. Under the action of centrifugal force, the material passes from the center to the edge of the grinding disc. Uniform movement, when passing through the grinding roller area on the grinding disc, is crushed by the grinding roller, the bulk material is directly crushed, and the fine material is squeezed to form a material bed for intergranular pulverization. The pulverized material continues to move toward the edge of the disc until it is carried away by the strong airflow at the wind ring, and the larger particulate material is again dropped onto the grinding disc to continue pulverization. When the material in the airflow passes through the upper separator, the rotor Under the action of the blade, the coarse particles are returned to the grinding disc for grinding. The qualified fine powder is ground together with the airflow and collected by the system’s dust collector. The collected powder is the vertical grinding of Huainan cement clinker. product. When the iron and other debris mixed into the material moves to the edge of the grinding disc, it cannot be blown by the wind due to its own weight. It falls to the lower chamber of the mill and is scraped into the bottom of the grinding disc and scraped into the slag discharge port. . By adjusting the rotational speed of the rotor of the multi-head classifier, qualified products of different fineness can be obtained. The roller grinding pressure can be adjusted by adjusting the pressure of the hydraulic system, and the raw materials of different hardness can be adapted within a certain range.

Technical advantages

  • The principle of material layer grinding, the product has high whiteness and clarity. The Gypsum Grinding Mill adopts the principle of vertical abrasive layer grinding, and the material has a short residence time in the mill, which reduces repeated grinding. The product contains very little iron and is used to whiten or clear materials with high whiteness and clarity. The specially designed roll sleeve and liner grinding curve makes it easier to form a powder layer.
  • The grinding roller is separately lubricated and the double pump supplies oil. Huainan cement clinker vertical grinding roller lubrication uses a separate lubrication station, and a single grinding roller circuit uses a double pump, pumping at the same time working mode, even if the grinding roller bearing is fully lubricated and cooled, and can ensure the grinding roller bearing indoor There will be no leakage of oil and leakage.
  • German Alpine powder selection technology can achieve the required fineness at one time. The Gypsum Grinding Mill adopts the principle of German Alpine multi-head sorting machine. Each rotor can be frequency-adjusted and regulated. The fineness of the finished grinding products can be realized within the selected range, without the need of secondary air separation and classification. exist. The finished product has a particle size of less than 2μ m has a high content of particles, a high level of up to 70%, and a low residue of 325 meshes, and is also suitable for secondary separation of finer-grained finished products.
  • Automatic control, frequency control, energy saving and efficient. The grinding pressure control method is automatically controlled by PLC/DCS, and the grinding pressure is precisely controlled without manual operation. The host PLC electronic control system carries out orderly coordination and command work on the electrical components within the host range. The Huainan cement clinker vertical mill main engine speed adopts frequency conversion speed regulation, saving energy consumption by 30%~50% compared with any other type of mill. , economic benefits.
