Magnetic Separator

Technical Parameters

Structure of Magnetic Separator

The magnetic separator is mainly composed of cylinder, roller, brush roller, magnetic system, tank body, and transmission part. The cylinder is welded by a 2-3mm stainless steel plate, and the end cover is a cast aluminum piece or workpiece, which is connected with the cylinder by stainless steel screws. The motor drives the cylinder, magnetic roller, and brush roller to rotate through the reducer or directly using a step-less speed regulating motor.The magnetic system is an open magnetic system, which is installed in the cylinder and exposed to full magnetism. The magnet block is installed on the bottom plate of the yoke with stainless steel bolts, the shaft of the yoke extends out of the cylinder, and an arm is fixed at the shaft end. The magnetic deflection angle can be adjusted by pulling the crank arm, and it can be fixed by the pull rod after proper adjustment. The working area of the tank body is made of stainless steel plate, and the frame and other parts of the tank body are welded with ordinary steel.

Working Principle of Magnetic Separator

After the pulp flows into the tank body through the feeding box, the ore particles enter into the feeding area of the tank body in a loose state under the action of the water flow of the mine spray pipe. Under the action of the magnetic field, the magnetic particles gather to form a "magnetic cluster" or "magnetic chain". The "magnetic cluster" or "magnetic chain" moves to the magnetic pole in the pulp under the action of the magnetic force and is adsorbed on the cylinder. Because the polarity of the magnetic pole is alternately arranged along the rotation direction of the cylinder, and it is fixed during operation, the "magnet cluster" or "magnetic chain" will produce a magnetic stirring phenomenon due to the alternating magnetic poles when the cylinder rotates, and the gangue and other non-magnetic minerals mixed in the magnetic pole fall off during the overturning, and are finally attracted to the surface of the cylinder is the concentrate.The concentrate is transferred with the cylinder to the weakest position on the edge of the magnetic system and is discharged into the concentrate tank under the action of the flushing water jet from the discharge pipe. The discharge is carried out by the brush roller. Nonmagnetic or weakly magnetic minerals are left in the pulp and discharged out of the tank with the pulp, which is the tailings.
