PRODUCT DESCRIPTION

The Roll Magnetic Separator is a type of dry magnetic separator featuring high magnetic field intensity, permanent magnets, and a roll-type design. It is used for the beneficiation and purification of low magnetic susceptibility materials with particle sizes ranging from 0.1 to 25 mm.
The magnets used are made from rare earth alloy materials, offering significantly stronger magnetic performance compared to conventional magnets. Because of this feature and the special magnet arrangement, very high magnetic forces are generated on the magnetic roll. These high magnetic forces enable the efficient separation of fine and weakly magnetic minerals at high yields.

​

WORKING PRINCIPLE

The machine consists of a supporting frame, feed hopper, feeder, magnetic and non-magnetic rolls, conveyor belt, drive motor, and control panel. Roll Magnetic Separators are typically used after crushing and screening processes. Minerals reduced to -25 mm in size and with a maximum moisture content of 5% are fed in a controlled manner onto the conveyor belt via the feed hopper and feeder.

​

As the conveyor belt moves over one magnetic and one non-magnetic roll, the material reaches the magnetic roll. Non-magnetic particles are thrown away by centrifugal force and directed to the non-magnetic discharge chute. Magnetic particles, however, remain attached to the belt due to the magnetic attraction of the roll and continue to travel until they exit the magnetic field. Once released, they fall into the magnetic discharge chute.

APPLICATION AREAS

Roll Magnetic Separators are used for removing iron impurities from ceramic and industrial raw materials as well as in ore beneficiation processes. They are also used in:

• High-purity quartz cleaning

• Magnesite beneficiation

• Processing of beach and mineral sands

• Limestone and dolomite purification

• Foundry sand cleaning

• Refractory raw material purification

• Boron beneficiation

• Chromite beneficiation

• Bauxite and feldspar purification

• Clay purification

• Glass sand cleaning

ADVANTAGES

• Antistatic Kevlar belt
• Direct-coupled motor or coupling-connected gearbox drive system
• Inverter-driven (variable-speed) drive unit
• Adjustable stainless-steel scraper blade
• Adjustable-speed vibratory feeder for uniform material distribution or feed roll for fine materials
