DC centrifugal crushers can be used for crushing, grinding and granulation of ore materials and nonmetallic materials of any strength, difficult-to-machine abrasive materials included.

The crushers are successfully used in the manufacture of crushed stone, building sand at the final stage crushing when basic quality characteristics of finished products are being formed.

The impact fracture of materials is realized in DC centrifugal crushers and mills making it possible to increase considerably the productivity of crushing and grinding processes and to obtain high-quality products with the required parameters, high profitability and effectiveness rates which are difficult to be achieved by the other known methods.

 

The failure of the material by impact taking place in DC centrifugal crushers comparing to that of cone, jaw, hammer and rotary crushers has a number of advantages:

• ·          the material is mainly cubiform;
• ·         the strength of the crushed material increases;
• ·         selectivity disclosure of mineral grains;
• ·         a high degree of mechanical activation of freshly crushed material.

The centrifugal crusher DC allows a high degree crushing of the materials to be gained which is hard to get in other crushing equipment similar in action in principal. It is achievable thanks to a high speed discharge of the material. The high speed is provided by the system of «gasostatic support» - a unique development of OJSC «NPO Center» specialists.

The application of the gasostatic support permits a high speed rotation of the crusher operating parts without vibrations at tangible unbalances and ensures a high reliability.

Advantages

Impact-centrifugal crushers make possible:

• * breaking of the material of any strength and hardness; 
• * considerable increase of reduction ratio; 
• * extension of control range of fractions in the product; 
• * changing of crushing and grinding correlation towards crushing and consequently – lower general costs for the final product obtaining; 
• * feed size reduction of grinding equipment at further stages of enrichment  rocess and the improvement of grinding process performance by no less than 30%; 
• * starting of enrichment at the stage of crushing at the cost of selectivity of impact fracture;
