Description
Technical Field
The invention relates to the technical field of ore dressing, in particular to an ore grinding and blending method based on the grade of hard rocks.
Background
The main processes of mineral separation at present are ABC and SABC. The ABC process calls oversize materials discharged from the semi-automatic mill, namely difficult-to-grind ores as 'hard stones', the 'hard stones' are crushed by a cone crusher and then returned to the semi-automatic mill, undersize materials of the semi-automatic mill are classified by a cyclone, qualified materials enter the next link, and unqualified materials enter a ball mill for regrinding. The process of the SABC flow comprises the steps of carrying out primary crushing on ores through a gyratory crusher, and conveying the crushed ores to an ore storage pile through a conveying belt. Ore produces segregation effect in ore storage piles, ore blending and distributing are carried out through a heavy plate feeder, ore is conveyed into a semi-automatic mill through a belt conveyor to be ground, ore discharge of the semi-automatic mill enters a linear screen, and the product on the linear screen is hard rock. The hard rock returns hard rock buffering storehouse through the belt, and the feed belt feeder gives into cone crusher under the storehouse and carries out the breakage once more, and half autogenous mill feed belt is given into once more to the broken back product and is returned the mill once more and grind. Qualified products under the screen of the linear screen enter a pump pool, a slurry pump is used for pumping the qualified products into a hydraulic cyclone unit for classification, settled sand enters a ball mill through a dust and sand nozzle of the cyclone, ore discharge of the ball mill returns to the pump pool, the ball mill is fed into the cyclone again through the slurry pump for classification, and overflow products of the cyclone, namely the qualified products, enter a flotation link. Because the amount of the hard rocks is less and cannot meet the requirement of a cone crusher, the hard rocks directly return to the semi-autogenous mill feeding belt.
The two ore-distributing modes of the existing ore dressing have limited control capability on the self-load condition of the semi-autogenous grinding mill, ore feeding amount, block ratio, ball addition, concentration and the like, limited control capability on the grade and larger grade fluctuation.
