Pendulum Roller mill
Pendulum Roller mill (PM)


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.


  • Low product residence time in the grinding section.
  • Absence of hydraulic system for the compression of the material.
  • Mechanical tightness via air pressure.
  • Greater internal ventilation than with other types of vertical mills.
  • Adjustable grinding to obtain required fineness with a minimum of over-grinding.
  • Low energy consumption.
  • Direct drying up to 20% product humidity.
  • Easy and efficient adjusting.
