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 3 ways to adjust the particle size of the product:

  • installation of grates with various openings;
  • installation of various number of blades;
  • change of rotor speed when the mill is equipped with a frequency converter.

OPERATIONAL SAFETY

The end switch excludes start-up with open milling chamber and automatically cuts off the power supply to the electric motor when the cover is opened.

The shock absorbers reduce the vibration transmitted to the bearing surface.

LABORATORY APPLICATION

Due to its small size and low energy consumption, CM 120M is suitable for use in laboratories.

COMPACTNESS

The new base allows installing the mill on a table or a stand. There is a cavity in the base to store accessories: blades template, rotor puller, thin-nose pliers. CM 120M has a compact built-in control panel.

COLLECTING CONTAINER

CM 120M is equipped with the quick-detachable collecting container of 2 liters.

A rubber seal of the discharge funnel reduces dust during operation.

Installation of a special nozzle for continuous unloading instead of standard collecting container is possible.

BUILT-IN CONTROL PANEL

The built-in control panel is designed to start and stop the mill and provides:

  • automatic shutdown when a power surge or short circuit;
  • motor overload protection.

LOADING FUNNEL

Easy loading of loose and fiber materials:

  • horizontal hopper with a pusher;
  • vertical shaft with a plunger.

The vertical shaft provides the convenience of loading fiber materials.

The hopper lid eliminates material ejection during the operation.

HIGHER RESOURCE

Increased service life of blades due to replacing of the casing blades and sharpening of rotor blades.

QUALITY SPARE PARTS

Knives are made of hardened tool steel.

Discharge grates are made of stainless steel.

CM 120M is equipped with blades template, rotor puller, thin-nose pliers.

DESCRIPTION OF THE DEVICE

In a cutting mill, comminution occurs due to cutting — shear deformations. The structure of CM 120M cutting mill includes: a loading funnel, a casing with fixed blades, a rotor with moving blades, a discharge grate, an unloading funnel, a base and an electric motor. An electric motor is installed on the base, to the flange of which a hollow cylindrical body is attached. In the upper part of the housing there is a loading funnel. It consists of a vertical shaft with a plunger and a horizontal hopper with a pusher. In the lower part of the body, a discharge grate is installed. The size of grate openings determines the size of the product particles

The milling chamber formed by the inner surface of the casing and the motor flange is locked by the front cover. Inside the milling chamber there is a rotor and seven blades: four fixed on the casing and three moving blades on the rotor.

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 and enters the unloading funnel.
