Cutting mills

Cutting mills are designed to comminute fiber, polymer and plant materials. 

In cutting mills, comminution occurs by means of cutting – shear strains of material particles between rotor blades and a housing.

The grain size of the comminuted product is regulated by the openings in the discharge grate and the physical properties of the material.

The CM 120 cutting mill is laboratory-class equipment designed for comminuting small batches of material with grain size up to 20 mm.

The CM 120 effectively comminutes fiber materials by crushing them with a plunger through a vertical shaft.

CM 120M is a tabletop modification of CM 120 cutting mill.

The CM 250 cutting mill is high-power equipment designed for busy laboratories or small production facilities.

* It is possible to batch load materials of an elongated shape, the size of which in one of the dimensions significantly exceeds the specified

** Depends on the physical properties of the material and the size of discharge grate openings

Advantages of VIBROTECHNIK Cutting mills:

  • Ability to obtain various comminuted material grain sizes by means of:
    • selecting the discharge grate opening size;
    • installing different numbers of blades in the housing;
    • cconnecting the Cyclone dust collector to CM 250.
  • Increased service life of blades as a result of sharpening and replacing housing blades (CM 120 / CM 120M);
  • Precise setting of minimum gap between the rotor blades and the housing provides shear forces on particles of the comminuted material;
  • Effective loading of loose and fiber materials in the CM 120 / CM 120M using a horizontal tray with a pusher and a vertical shaft with a plunger;
  • Equipment of the CM 250 with receiving containers for three discharge modes: to the receiving container, through a dust collector and combined;
  • Equipped with patterns, extractors and a special maintenance tool;
  • Uniform feed of loose material using a Vibratory feeder PG 1 (CM 120 / CM 120M);
  • Connection of CM 120 / CM 120M to single- and three-phase electrical circuits.
