Cement production equipment

Vertical mill, ball mill, cement mill, tube mill ' slag grinding, grinding of raw materials, raw mill ' air swept coal mill, air swept mill, coal mill, can be widely used in electric power, metallurgy, building materials, chemical industry, coal pulverizing system, suitable for grinding bituminous coal medium hard materials, especially large for burning bituminous coal pulverizing system. The machine has the general medium speed coal mill low unit power consumption, small occupation area, coal pulverizing system, low noise, simple operation and reliable characteristics, but also has big crushing ratio, long service life of grinding parts, the whole operation period output variation is small, the material has wide application range, high, low load has good applicability unique advantages.

Coal grinding machine three roller by rotation of the disc drive for milling operation. The grinding material by the center for coal drop pipe falls on the disc, the centrifugal force generated by the rotating disc it is being transported to the mill roller bed grinding. Grinding pressure by a spring or hydraulic pressure device to produce, through static three point system, the milling force and uniformly onto the three roll, by pressurizing the system pressure to the foundation. Pulverized coal drying and conveying by using hot air to. The hot air passes through the nozzle ring is uniformly distributed on the disc around, the milled material drying and transported to the upper part of the separator mill. Material thickness powder this separation, fine powder discharge mill, coarse powder returned to mill grinding. Material in some can not be broken material through the mill lower deslagging mouth. Coal grinding machine is mainly composed of a basic part, reducer, rack, rack machine, grinding, grinding roller, compression device, separator, positive pressure air sealing device, the steam blowing device and other components, is also equipped with a main motor, a lubricating oil station, a hydraulic station and a sealing air fan and other ancillary equipment, another with slow drive device, installation and maintenance special tools, escalator platform, pulverized coal distributor, fast valve and other ancillary equipment for users to choose. Coal grinding machine with hydraulic pressure system, in the operation of grinding pressure can be adjusted, and has better passing-iron protective performance. In the original basis of the standard model to increase the grinding roll out device, and improves the grinding body antiknock ability.
