HRM Vertical Mill applies to grind coal, coke, cement raw material, gypsum, barite, phosphorite, calcite, kaolin and other medium degree hardness solid material. HRM series vertical mill is integrated with crushing, drying, grinding and separating. Process flow is easy. Compared with tube mill, vertical mill has many advantages. High grinding efficiency; Reducing 20-30% electricity consumption; Big drying ability; Material moisture can be 15%; Material in-size is bigger; Degree of product fineness is easier to adjust; Chemical composition is steady; No steel ball impact; No direct touch between metals; Low noise; Low wear; There is separator in mill, no need to match powder concentrator; Small cover area; Grinding rollers can be taken out of the mill; Easy maintain and so on.

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..
