FIELD: mining.
SUBSTANCE: underground concentrating mill consists of crushing and sieving complex and concentration complex. The crushing and sieving complex consists of two or more similar sections each intended for processing of ore of the same quality. The receiving bins, the crushers and the sieve of each section are arranged one above another and connected by the same ore chute to provide gravity-flowing movement of ore. In the lower part of the mills flows of shredded ore of each section are integrated in one bin where ore is homogenised for subsequent concentration.
EFFECT: improvement of efficiency of underground concentration of ore, decrease of capital and operational expenses.
