About reducing energy consumption during the sands concentration process

The article analyzes the results of the production study of the effect of sand-size segregation in the conical screen underflow pipeline. These results lead to the identifying of the main requirements to the construction of tapering chute. The work gives the results of the laboratory study of the tapering chute model. The results prove the possibility of sand benefication without using additional energy. The schematic diagram of sands enrichment technology in tapering chutes in the gravity hydrotransport process with the expected quality indicators is offered.
