EP Service

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.

Solution

Power industry
