The ore powder produced by our company's vertical roller mill can be used in the field of cement. Not only can the ore powder be widely used, but it can also ensure the quality of the cement, and also obtain great economic benefits. The vertical mill has a large output and low energy consumption, which fully meets the measurement requirements for the construction of large-scale milling stations. Vertical mill production process, slag fine powder production line, a large number of slags will be generated during the opening of the crushing yard and ore mining. After long-term accumulation, the number of slags generated will be innumerable. If they are not used, they will waste recycling resources. Therefore, in recent years, the rational treatment of slag has become one of the problems that have been solved. With the development of the domestic economy and the continuous improvement of related technologies, slag has also been effectively solved. The vertical mill is a necessary equipment for processing high-hardness ore, and it is also a necessary equipment for slag processing. This equipment is a deep processing equipment developed by SBM for industrial waste processing, making it well used in slag deep processing applications. To achieve the goal of zero pollution and zero emissions, this equipment can fully meet all the requirements of slag processing, and has not brought large profits to investors. The following is the structure principle of SBM heavy machinery slag vertical mill: The raw slag of the slag vertical mill enters the feeding bin through the grabber, and is fed by the conveyor belt into the screw feeding device and fed into the SBM roller vertical mill. After the measurement, the material rotates with the grinding disc from the center to the center under the action of centrifugal force. The edge moves. After the process of compaction, deaeration and grinding, the material is taken up by the hot air entering from the air ring on the edge of the grinding disc and dried instantly. The finer particles are taken to the classifier for sorting, and the coarse powder is returned. Grind the disc again. 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.
