Rollers - Import export

The Cylinder mill, commonly known as the Roller Press works by crushing the material between two cylinders kept under pressure by a hydraulic system (2 to 10 T/linear cm). This mill uses a patented process of pulsating pressure that reduces the level of vibration and contributes in reducing energy requirements and prolonging the service life of wearing parts. It is able to treat high production capacities (up to 500 T/h) and produce fine particle sizes (10 to 1000 microns). Cylinder mills allow for energy savings of up to 30% compared with mills that use traditional crushing methods. The cylinders are equipped with an antiabrasive coating which combined with their slow processing speed provide the grinding solution with the longest service life on the market.

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.
