APPARATUS FOR PROCESSING CARBON-CONTAINING WASTES OF MINES AND DRESSING FACTORIES Russian patent published in 2017 - IPC B03B7/00 

FIELD: mining.

SUBSTANCE: invention relates to separation of solid materials in recycling industrial wastes using combined methods, more specifically to a plant for processing carbon-containing wastes of mines and processing plants and can be used in complex processing of a significant amount of waste rock, in particular, from Moscow and Chelyabinsk coal basins, as well as for processing fly ash of thermal power plants to produce at output aluminium silicates, carbon and iron-containing minerals. Apparatus for processing carbon-containing wastes of mines and processing plants includes means for fractionation of raw material in separating medium. Means for separation of suspension of carbon-containing wastes by fractions comprise a screen for preliminary classification, first and second inputs of which are connected to outputs of loading hopper and roll mill. First and second outputs of screen are connected to inputs of roll mill and first hydraulic cyclone, first output of which is connected to first inputs of hydraulic classifiers and screw separator. Second output of first hydraulic cyclone is connected to first input of thickener, which is also connected with first outputs of screw separator and second hydraulic cyclone. Second input of thickener is connected to output of first accumulation vessel for flocculant, first output of thickener is connected to second inputs of screw separator and hydraulic classifier. Second output of thickener is connected to input of electrodynamic separator, first and second outputs of which are connected to inputs of second and third accumulation tanks for iron-containing minerals and aluminosilicate product. Outputs of hydraulic classifiers and screw separator are connected to first and second inputs vibration dryer, third input of which is connected to second output of second hydraulic cyclone. First and second outputs of vibration dryer are connected via pump with input of second hydraulic cyclone and input of fourth accumulation vessel for coal concentrate. Electrodynamic separator is made in form of inclined endless conveyor belt, installed on upper drive and lower driven drums with possibility of movement of working section of conveyor belt from below upwards and supply of separating medium in form of water to upper, and wastes of thickener to lower working part of conveyor belt. Lower driven drum of inclined conveyor is made hollow from dielectric material, inside of which there is a magnetic rotor with possibility of independent rotation.

EFFECT: high efficiency of deep complex processing of carbon-containing wastes of mines and concentrators.
