Double Roller Mill

Crushing with shear and compressive forces

Crushing & Milling in the double roller mill is carried out by two counter-rotating rollers, which draw the ground material into the roller gap and crush it using pressure and shear.

The double roller mills are equipped with smooth rollers as standard, which limits the maximum particle size due to the frictional intake conditions. To improve the feed conditions, profiled rollers are required, which we can also offer. The double roller mill can usually achieve a comminution ratio of 1:2 … 1:5 up to a maximum of 1:20.

An infinitely adjustable roller gap

One of the two rollers is rigidly arranged, the second roller can be adjusted manually, motorized or hydraulically via a spindle. The set roller distance can be read off a scale or recorded digitally via a sensor.

A reversible overload protection

Spring assemblies allow the movable roller to evade smaller, non-breakable materials.

High force transmission into the movable crushing roller

by mounting them on a rocker, high compressive forces can be generated in the roller gap.

Low-wear/low-contamination Crushing & Milling with crushing rollers made of

Cast steel, tungsten carbide or all-ceramic

Further options

  • Measuring the forces in the roller gap and recording the torques of the rollers.
  • Variable-speed direct drives or V-belt drives. Machines for installation in hazardous areas, with the option of inerting the grinding chamber.
  • Specific surface quality requirements are also part of our range of services.
