Cascade gravity classifiers









Linked profile in other language
Artsem Makarevich
NPO Center offers consumers cascade-gravity classifiers on the basis of a production agreement, is looking for partners to conclude an agreement on distribution services, as well as partners interested in purchasing technology for the production of cascade-gravity classifiers under a license agreement.
Cascade-gravity classifiers for the separation of coarse materials into specified fractions in an air flow in the size range from 0.1 to 5.0 mm.
The separation of materials occurs due to the action of the field of gravitational forces and air flow on the particles of the material. The design implements a cascade separation system, when the classification process is repetitive, which makes it possible to achieve high separation accuracy. Cascade-gravity classifiers can operate in a closed loop through air, that is, all or most of the air from the aspiration system returns to the classifier.

Innovative aspects of the offer - Getting marketable products from crushing screenings. Cascade-gravity classifiers can be used to separate any bulk materials, in particular, crushing screenings into several fractions and obtain building materials such as fine cube-shaped crushed stone, sands of a given size module, fine fillers for concrete and asphalt concrete, filter powders, abrasive powders, etc. . NS.
Advantages and Innovations
The design provides the ability to regulate the fractional composition during operation without stopping production. When separating materials larger than 1 mm, classifiers allow processing it without preliminary drying with material moisture content reaching 3%.
