170-280 TPH Drum Type Magnetic Separator Ore Dressing Machine Stable

high quality magnetic separator stable and reliable ore dressing machine

Magnetic Separator is a device which is designed to assist with the purification and separation of process streams. The heart of each separator is magnetic system, which adopts high quality ferrite materials and rare earth magnets, the average magnetic induction intensity on the shell surface is 100~600mT. This product has the advantages of simple structure, big processing capacity, convenient operation and easy maintenance.

Features

1. The strength of magnetic field is large in the surface of tube;
2. Large wrap angle of magnetic system;
3. The strength of magnetic field is stability;
4. The transmission system is stable and reliable;
5. Can significantly improve the grade of ore before it is into the mill.

Working Principle

The pulp flows into the trough from the pulp box, and under the water flow of the feeding spray pipe, the ore particles will go into the feeding area of the trough in the loose condition. In the magnetic field, the magnetic ore particles will have magnetic gathering and form magnet group or magnet chain which is influenced by the magnetic force inside the pulp and moves to the magnetic pole, finally can be attached to the cylinder.
Since the polarity of the magnetic pole along the rotary direction of the cylinder is alternately arranged and fixed when working, when the magnet group or magnet chain rotate with the cylinder, it will have magnetic mixing due to the alternation of the polarity, as a result of which, the non magnetic ore such as gangue mixed up with the magnet group or magnet chain will drop down during the rolling process, and the magnet group or magnet chain that is finally attached to the surface of the cylinder is concentrate. The concentrate rotates to the edge of the magnetic system where the magnetic force is the weakest along with the cylinder, and under the water flow of the discharging spray pipe, it will be discharged to the concentrate chute. If the roller is all magnetic roller, the ore discharging is completed by brush roll. The non magnetic and weak magnetic minerals are kept in the pump and are discharged from the chute with the pulp to become gangue.
