ADVANTAGES

MILLING EFFICIENCY

The accuracy of setting the gap between the casing blades and the rotor blades provides shear deformation during grinding.

PRODUCT PARTICLE SIZE AJUSTMENT

There are 4 ways to adjust the particle size of the product:

  • installation of grates with various openings;
  • installation of various number of blades;
  • connection of the dust collector;
  • change of rotor speed.

EASY MAINTENANCE

Hinged loading hopper provides quick access to the milling chamber for inspection and replacement of blades and grates, and cleaning of the chamber. Easy adjustment of V-belt drive.

VARIOUS UNLOADING MODES

Design of CM 250 cutting mill allows 2 modes of material unloading:

  • Unloading into collecting container;
  • Combined unloading: large particles precipitate in the collecting container, small particles precipitate in the dust collector.

COMPATIBLE WITH DUST СOLLECTOR

Ability to connect to dust collector to:

  • increase the output (up to 20%);
  • lower the temperature in the milling chamber;
  • lower the content of dust fraction in the product;
  • separate the material into three fractions: precipitated in the receiving container, cyclone and bag filter.

OPERATIONAL SAFETY

The end switch excludes start-up with loading hopper removed. The size and configuration of the loading hopper preclude access to the milling chamber. Bumpers in the hopper exclude the material ejection from the milling chamber. All rotating parts and assemblies are covered by the casing.

 

QUALITY SPARE PARTS

Knives are made of hardened tool steel. Increased service life of the blades due to the possibility of sharpening. Discharge grates are made of 5 mm steel. CM 250 is equipped with blades template and puller.

DESCRIPTION OF THE DEVICE

In a cutting mill, comminution occurs due to cutting — shear deformations. The structure of CM 250 cutting mill includes: a frame, a housing, a loading hopper, a rotor, a folding support, a discharge grate, a collecting container and an electric motor.

The mill with loading hopper is mounted on the frame. The main working body of the mill is the rotor, which has a three-beam shape. It has three moving blades. On the casing two fixed blades are mounted. In the lower part of the body there is a folding support with discharge grate. The size of grate openings determines the size of the product particles. Torque from the electric motor is transmitted through a belt drive. In the lower part of the frame the collecting container is installed.

CM 250 cutting mill can be equipped for two unloading modes:

  • with the standard collecting container;
  • with a shutter for the cyclone dust collector connection (for combined unloading).

OPERATING PRINCIPLE

The material fed through the loading funnel into the milling chamber. Milling (cutting) of the material occurs when particles enter between the casing blades and the rotor blades. The milled material passes through the openings of the discharge grate into collecting container.

When cyclone dust collector is connected, small particles of the comminuted material are captured by the air flow. The air flow passes through the shutter into dust collector, where material is precipitated in the cyclone and air is filtered in the bag filter.

PRODUCTION OPTIONS

  • Complete with a shutter for the cyclone dust collector connection or complete with cyclone dust collector with hood;
  • Complete with equipment for various unloading modes:
    • Unloading into collecting container;
    • Combined unloading: large particles precipitate in the collecting container, small particles precipitate in the dust collector.

SPECIAL OPTIONS:

  • Complete with a frequency converter;
  • Complete with increased height frame;
  • Complete with increased height loading hopper.
