Gateways of fine filling, gateways of deep filling

Description

Gateway - sloping narrow and long rectangular trough for discharge from the pulp the particles of high density and size: heavy minerals sink to the bottom, keeping on rough surfaces or stencils. The resulting eddy currents contribute to the selective enrichment. After accumulating of material the gateway is washed (wash with powerful water jet of concentrate to a separate receiver). 

 

There are gateways of deep filling (stream height is greater than 30-40 mm) for the enrichment of material larger than 20 (16) mm and the gateways of fine filling for enrichment of material smaller than 20 (16) mm.
