The POITTEMILL pendulum roller mill is a vertical mill that works by compressing the material bed. The pendulums mounted on a star wheel are driven by a vertical shaft. Each pendulum is fitted with a grinding roller that rotates upon its axis.

The rotation of the star wheel combines with the articulation of the pendulum to generate a centrifugal force at the grinding roller level.
The product is ground between the grinding roller and the fixed bull ring.

The raw material is introduced into the machine through the feeder and falls to the bottom of the mill. Rotating plows scoop up the raw material and project it between the roller and the ring where the grinding takes place.

Air enters the mill though ports in the base under the grinding ring, and sweeps the fines and medium fines upwards. The grinding chamber acts as a first classifying stage.

The particles mixed with air enters into the classifier above the grinding chamber. The ground material is classified and the oversized particles returned to the grinding chamber for further reduction.

The fine particles are carried to the cyclone collector or the air-filter, separated from the air and discharged.
