Description

Task of KG classifying complexes is the separation of granular and powder uniform-sized particles according to their density or fineness.

KG screening complexes are efficient in producing fine fraction crushed stone, building sand, and mineral fillers from the grinding screened material, which is accumulated as crushing and screening production wastes.

KG classifying (screening) complexes include the sequential technological classification system based on the modular units that are notable for:

low power consumption,
ease of operation,
low spatial requirements,
high performance.
Accuracy of separation at Ural-Omega screening complexes reaches 95%.

In the course of KG classifying (screening) complex work it is possible to produce 2-3 classes of the narrow fraction finished products with the fineness of 0-5(10) mm. Complex productivity is 1 – 60 t/h.

KG screening complexes’ operation is based on the cascade-gravity material classification principle, which consists in the particle segregation by an air flow according to their density or fineness.

Freedom from mechanical screen sizing systems and sieves is an important feature of KG classifying (screening) complexes. Material screening is carried out entirely due to air flows and multiple duplication of sections and chambers of the classifier.

Classifying complexes do not require service maintenance. All units are free from lubrication systems and wear parts, due to which the complex use factor reaches the value of 0.95.

Currently there are more than 25 KG classifying (screening) complexes operating on the territory of the Russian Federation and CIS countries, which are allocated to different tasks, such as: production of fine aggregates, building sand, mineral fillers, ore and non-ore materials roughing, as well as sand fractionating and screening, crushed stone dedusting, removal of powdery wastes from the abrasive materials, elements extraction of useful from the industrial wastes.

KG classifying complexes are the fully automated up-to-date equipment. Standard equipment set includes frequency converters that control safe units operation.

Operation of the complexes is equipped with a feedback system for finished product preset quality parameters, which enables the immediate ACS (automated) response for changes in the initial parameters of the material.
