Xinhai’s beneficiation equipment provides peace of mind with supply, installation and asset management and flow sheet solutions all managed by experts in their fields.
In terms of iron ore beneficiation, a complete set of iron ore beneficiation equipment includes jaw crusher, ball mills, classifiers, magnetic separator, flotation machine, thickener mining, and dryers. Elevator, belt conveyor, etc.
1.Large raw iron ore for primary crushing are fed into the jaw crusher by Plate feeder and are reduced to 8 inches or smaller. After first crushing, the material will transferred to cone crusher by belt conveyor for secondary crushing; the crushed iron ore stone will then transferred to vibrating screen for classifying. After classifying, the parts whose size below the mesh size will be transferred away as final products, while the other parts will return to cone crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement.
2.The smaller crushed iron ore is fed to ball mill for grinding. Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls.
3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore (~-0.074 mm) going to froth flotation cells for recovery of iron.
4.In magnetite processing plant,the process of flotation separation is replaced by magnetic separation. The minerals are conveyed to the permanent magnetic dewatering tank for concentrate and then concentrate will enter permanent magnetic drum for a second magnetic separation. The concentrate after filtration and drying are conveyed to warehouse for storage.
