Fast Moving Parts
External circulating system (basically used for cement raw meal final grinding and clinker semi-final grinding)
Adopt external circulating elevator for material. circulation, reduce the system air pressure, significantly reduce energy consumption of the syetem .
Single stage dust collecting system 1
The dust collecting device is adopted with explosion-proof bag filter and the discharge air enters into dust collector directly. This system reduces installation of numbers of equipments simplifies system configuration.
Single stage dust collecting system 2
The dust collecting device can be adopted with a high concentration. EP or bag filter, the discharging air enters directly into the dust collector. This system reduces the number of equipment and simplifies the system configuration.
2nd stage dust collecting system
Cyclone dust collector is adopted for collecting product. This arrangement is helpful to reduce the system's negative working pressure and air volume passing through the dust collector. EP or bag filter can be used as final dust collecting equipment..
Scope of Application
The materials to be ground range from highly wet to dry materials, from exceptionally difficult to easy to grind materials, and the product fineness ranges from coarse to fine, with a wide range of grinding fields and abundant grinding types.View more >
HRM vertical mill series vertical mills are widely used in different industries such as electricity, metallurgy, chemical and nonmetal mineral for the grinding of cement raw meal, clinker, mining slag, steel slag, coal,gypsum, calcite, pyrophyllite, bentonite，bauxite，quartz and limestone powder for sulfur treatment in power plant, etc.
HRM slag vertical mill is widely used in steel and mines for efficient pulverization, no need for two-stage grinding, saving more than 40% of electricity than ball mill! Steel slag, water slag, limestone large-scale production, with drying hot air, the fineness of the product to more than 500m2/kg....
