In recent years, due to advances in powder processing technology, gray calcium powder products with a fineness of 600 mesh or higher have been available on the market. So how to choose hammer crusher and slag vertical roller mill for processing ore and slag? The following SBM heavy machine recommends comprehensive processing equipment for you. SBM heavy machine ore high pressure mill is suitable for crushing various ore chemicals Grinding of non-metal raw materials such as raw materials, such as iron ore, pulverized coal, blast furnace slag, desulfurizers for power plants, coal injection by boilers, white ash, feldspar, quartz, gypsum, barite, limestone, ceramics, Non-flammable and explosive mining, metallurgy, chemical, building materials and other industries with more than 280 materials with high Mohs hardness of 9.3 slag and no more than 9.3 hardness and humidity of less than 6%. Adjustment (fine 1000 mesh). The processing fineness of SBM heavy machine slag vertical roller mill is finer than that of high pressure mill, and the fineness can be adjusted arbitrarily between 300 mesh and 3000 mesh.

The residue after ore beneficiation or smelting is called slag. The slag is widely used after being processed by slag vertical roller mill equipment. In industrial production, slag plays an important role, especially some major factories. The slag is made into slag cement, slag fine powder, slag powder, slag portland cement, slag cotton, blast furnace slag, granulated blast furnace slag powder, copper slag, and slag vertical roller mill. Saved energy. The main component of gray calcium powder is a mixture of Ca (OH) 2, CaO and a small amount of CaCO3. It is a refined product of lime. It is a natural high-quality limestone with CaCO3 as the main component. It is selected, partially digested, and then pulverized by a high-speed air-selection hammer mill, and its appearance is white and delicate.

The working principle of SBM heavy machine slag vertical roller mill: The raw slag of the slag vertical roller mill enters the feeding silo via a grabber, and after measurement, it is fed by a conveyor belt to a screw feeding device and fed into a ZJTL roller vertical roller mill. The rotation of the grinding disc moves from the center to the edge under the action of centrifugal force. After compaction, degassing and grinding, the material is taken up by the hot air entering from the wind ring at the edge of the grinding disc and dried instantly. The finer particles are brought to the The separator is used for sorting, and the coarse powder is returned to the grinding disc for grinding. 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. Some difficult-to-grind large-grain materials (and iron knobs and iron slag) enter the external circulation system through the slag outlet at the wind ring. After removing iron, they are fed into the mill by the hoist and ground again. The hot air required for mill drying and ventilation is provided by a hot blast stove, and the shortfall is supplemented from the atmosphere by a cold air valve. The system has large air volume and strong drying capacity, and the moisture of the material into the mill can reach 8-15%
