The invention belongs to the technical field of mechanical processing, in particular to a complex ore beneficiation process containing magnetite. The crushing and beneficiation device used comprises a frame body. a conveyor belt; an airbag is arranged in the first conveyor belt and a fixing plate is fixedly connected to the outer surface; a second groove is formed in the fixing plate; the insertion rod and the push plate are arranged in a staggered manner in the second groove; The push plate and the plunger are hinged to the sixth shaft, and a cylinder is fixedly connected to the inner wall of the second groove; the outer surface of the crushing roller is provided with a first groove, which passes through the third shaft, the fourth shaft and the fifth shaft. , the collar, the insertion rod and the second conveyor belt form the first crushing roller and the second crushing roller; the surface of the crushing roller and the grinding roller is fixed with a magnet; this process can cut the ore before it is crushed, and magnetize it during grinding. Selection, improve work efficiency, prevent waste in the transportation process, resulting in waste of raw materials. |
