High Field Intensity Roll magnetic separators provide maximum efficiency, especially in the enrichment of iron ores with weak magnetic properties and in the removal of magnetic impurities in industrial raw materials.

The magnetic properties of iron minerals are very variable, of which magnetite is strongly magnetic, siderite, hematite and limonite are weakly magnetic and pyrite is non-magnetic. Important gangue minerals such as silica found in iron ores belong to the non-magnetic group.

RE (Rare-Earth) Roll Type Separators are used in the separation of anti-ferromagnetic (weak ferromagnetics: limonite, hematite, mica, biotite, siderite, etc.) from stone, quartz powder, magnesite, silicon carbide, etc. which are the most important part of mineral enrichment systems, providing high field intensity, especially for the enrichment of dry industrial raw materials, such as sea sand, feldspar (in ceramics), silica sand (glass production), calcium carbonate, kaolin clay, garnet, gypsum. It can easily separate nickel cobalt from titanium and zirconium.

Advantages;

• High Field Intensity Roll Separators made of permanent rare earth magnets are preferred because they have lower investment, operation and maintenance costs compared to electromagnetic separators.
• It can be easily embedded even in systems of already operating facilities.
• The cost per ton is lower.
• Its dimensions are small and light, as it does not require any power source to create a high-capacity magnetic field.
• It can be easily deployed even in existing facilities without the need for major modifications, with minimal maintenance costs.
• Permanent magnet magnetic separators made of rare earth elements, with high field intensity, have a very wide usage area because of their superior economic and technical features compared to electromagnetic separators. The use of permanent magnet magnetic separators with higher field strength and lower production cost is the most preferred magnetic separator, especially for the enrichment of dry industrial raw materials.

Working Principle:

Roll type magnetic separators separate the magnetic or weak magnetic grains passing over the magnetic roller from non-magnetic grains by deflecting their orbits with magnetic force.

The design of the Roll type dry RE magnetic separators is quite simple. This type of magnetic separators consist of two rolls, one magnetic in the front, a thin and durable tape that provides material transfer and a separator blade which separates magnetic and non-magnetic materials from each other. Feeding is usually done by an adjustable vibratory feeder and feedroll.

In High Field Intensity Roll Separators, the operating parameters affecting the magnetic separation are as follows:

• Roll rotation speed (Depending on demand, our systems can be made with a speed control panel where you can adjust the rotation speed of the drum.
• Feed grain size
• Divider blade adjustment
• Tape thickness
• Magnetic coil configuration and number of stages.

You can manage your raw material enrichment processes, which are very sensitive about glass, ceramic, porcelain, refractory production, etc. about body iron.
