Magnetic Separator

Capacity:0.5-180t/h
Material
Widely used in mineral processing, coal washing and chemical industries for strong magnetic minerals that wet classification size ranges from 0 to 6 mm, and divides the minerals into magnetic and non-magnetic materials. It often processes strongly magnetic materials such as magnetite, magnetic pyrite etc.

Features

Magnetic system is compounded of ferrite and permanent magnets; the average magnetic induction intensity of cylinder surface is 100～600mT
The same cylinder can be equipped with three types of tank adapting to different dressing process.
Small area taken, good separation for magnetic mineral, reduce the load of next process

Working Principle

After the ore pulp flows to the magnetic groove via the feeding box, the mineral particles in the loose status enter the feeding zone driven by the current of the feeding spray pipe. In the magnetic separator, the magnetic particles gather together to form a magnetic group or magnetic chain which moves toward the magnetic pole in the pulp’s magnetism effect and is absorbed to the cylinder. As the polarity of the magnetic poles is arranged alternately along the cylinder rotating direction and is unchangeable during the operation, the magnetic group or the chain rotating with the cylinder will mix with each other because of the alternate magnetic pole. Non-magnetic materials like the gangue mixed in the magnetic group or chain will split away during the rotation and be absorbed to the cylinder surface, thus producing the concentrate. The concentrate turns to the weakest position of the magnetic system edge and then is washed away to the concentrate groove by the water sprayed form the ore unloading pipe. If the magnetic roll is the complete magnetic one, we will use the brush roll to unload the minerals.
