"NPO Center" offers consumers centrifugal impact mills for dry grinding of ore and non-metallic materials under a manufacturing agreement and is looking for partners to conclude a distribution services agreement, as well as partners interested in acquiring the technology for the production of centrifugal impact mills under a license agreement.

Centrifugal impact mills are designed for dry grinding of ore and non-metallic materials of any strength and hardness.

Centrifugal impact mills MC can be used both as part of a grinding complex and independently of other elements of the complex, as a separate unit in existing process lines. To decide on the feasibility of using MC in a given line, contact the specialists of NPO "Center".

Operating principle.
A high-pressure fan creates air pressure to form a "gas bearing" (air gap) between the rotor and the stator. The engine drives the mill accelerator through a cardan transmission. The initial crushing product is fed through a loading hopper to a separating cone and distributed along the accelerator channels. Having received the required peripheral speed, the material enters the crushing chamber, where it is crushed due to impact with the lining surfaces and mutual collision of particles. In the air flow crushing chamber, the primary classification of the material is performed: separation of under-crushed particles for return to the mill. The crushed product is carried by the air flow into the built-in air classifier of the mill, where the process of fine separation of the obtained material takes place: the separated under-crushed particles are returned for additional grinding to the crushing chamber.

Particles that satisfy the specified size range, in the form of a dust-air mixture formed during the grinding process, are fed into the technological scheme of the grinding complex for separation by fractions and sedimentation of the finished product.

Unique design solutions embodied in the machines of NPO "Center" make it possible to rotate the working parts with large masses and speeds with significant imbalances. Classifiers included in the mills serve to remove material of the required size from the grinding zone and return the under-crushed product for additional grinding.

The equipment is characterized by:
- low material consumption;
- low vibration level, which allows it to be placed without foundations at any elevation of the production building;
- low capital and operating costs;
- ease of maintenance.

Centrifugal impact mills are successfully used at enterprises in Russia, Belarus, Kazakhstan, Ukraine and other countries.

The method of centrifugal impact grinding, implemented in the grinding complexes of NPO Center, allows to obtain a material characterized by quality indicators that are unattainable using other types of grinding.

The crushed product has a high specific surface area and physicochemical activity of particles, has a specified narrow granulometric composition.
