Magnetic Separation Processing Flow

Magnetic separation process is a kind of magnetic separation process method of magnetite combined wet and dry beneficiation. The magnetic separation process is mainly to carry out three-stage magnetic separation of mineral powder, and then through wet material magnetic separation. The magnetic field strength selected for magnetic separation is 400 ~ 1200GS, the magnetic roller speed is 60 ~ 320 RPM, and the wet material is dehydrated into finished iron concentrate powder. 

General iron content in 35% of the ore, after this method of magnetic separation of iron concentrate powder iron content can reach 68 ~ 70%, the combined process method, ore utilization rate can reach 90%, less water consumption in the process, save water, reduce costs, reduce pollution, magnetic separation dust by the dust removal device, will not cause air pollution, this method is a high production efficiency, good product quality, Creative process methods without environmental pollution.

General Conditions

When mineral particles pass through the magnetic field of the magnetic separator, they are simultaneously subjected to the joint action of magnetic and mechanical forces (gravity, centrifugal force, medium resistance, friction, etc.). The magnetic force of the ore particles with strong magnetism is greater than the mechanical force, and the magnetic force of the non-magnetic ore particles is small, and the mechanical force predominates. Due to the different combined forces of magnetic and mechanical forces acting on various ore particles, their movement trajectories are also different, so as to achieve the final separation of minerals. In order to successfully separate the magnetic particle, the necessary condition is that the magnetic force of the magnetic particle must be greater than the combined force of the mechanical force in the opposite direction.

Main Process

The process of magnetic separation and beneficiation production line is roughly: 

(silo) – feeder – jaw jaw crusher, cone crusher, vibrating screen, ball mill, spiral classifier, magnetic separator (powder) can be obtained. The machines in between can be connected by conveyor.
