When the HGM series powder grinding mill machine begin to work,  the motor drives the main shaft and every turnplate through the reducer. Small material crushed by hammer crusher or jaw crusher is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turnplate evenly. The material falls to the grinding chamber under the centrifugal force and comes down to raceway of ring to be grinded  into powder. The blower inhales the external air into the grinding mill machine and carries the powder after third turnplate into powder-separator. Turbine in the separator makes the coarse powder drop down and regrinded and the fine powder shall go into cyclone powder collector together with air current and go down through discharge valve as final product.

The whole system for the grinding mill plant (This system normally include the crusher, bucket elecvator, electric magnetic vibrating feeder, HGM grinding mill machine etc)

1. Spring booster, increase grinding power, high productivity and high efficiency
2. Low energy consumption, in the case of the same yield and fineness, the system energy consumption is only one third of the airflow mill
3. Modular design of the powder separator, a wide range of applications
4. The new sealing structure, long maintenance period, more energy-saving, easy to maintain.
5. Pulse dust removal, automatic cleaning

The technology for the linkage of grinding rollers to boost pressure could make the machine operate steadily, increase the grinding pressure and improve the processing capacity obviously.

Adopting turbo-type analyzer and variable frequency motor, the machine has the following advantages: high efficiency of classification,low resistance and large processing capacity.

Adopt high-pressure centrifugal air blower to save energy and increase efficiency.
