INDUSTRIAL HIGH INTENSITY HIGH GRADIENT DRY PERMANENT MAGNETIC ROLLER SEPARATORS
Industrial High Intensity Magnetic Roll Separators Introduction:
STAR TRACE High Intensity Magnetic Roller Separators are roll type dry intensity magnetic roll separators with fixed magnet having high field intensity and gradient. The roll type magnets used in the Roller Magnetic Separators are made of alloys of rare earth magnetic elements and more powerful as compared to other magnetic magnets. They generate high magnetic attraction forces on the magnetic roller due to their magnetic properties and special magnetic series. The obtained high magnetic attraction forces have low magnetic sensitivity and therefore they make it possible for this high magnetic force to separate very fine low magnetic minerals with a high recovery.
The most distinguishing property of Intensity Magnetic Roll Separators are used in roll magnets that are an alloy of rare earth magnetic elements produced domestically and more powerful magnetic force.. Magnetic Roll Separator Systems have a number of standard sizes in which the high gradient roll magnetic separators are produced, and all of this type require a low installation height. It is also possible to make a Magnetic Roll Separator system in accordance with customer specifications. Depending on the requirements made and the application, a choice can be made for a single stage Magnetic Roll Separator system or multiple stage magnetic roll separator under one another. This results in an even higher degree of iron separation.
Our latest developments in higher gauss value with star ultra super rare earth magnetics with highest intensity ,high gradient type magnetic arrangement in special proprietary configurations are now available after extensive research and development.
STAR TRACE is one of Asia's leading Magnetic Roll Separator manufacturing Company in Permanent Magnetic Equipments and Vibrating Equipments in Dry/Wet type Separation of minerals and metals. The Dry Permanent Intensity Magnetic Roll Separators systems are unique in nature and we are supplying similar magnetic equipments throughout the world and more than 1000 Industries are having our magnetic Equipments. In our past 25 years of experience, we can separate from Coal to Gold in all minerals and metals from anywhere in the world, depending upon on their mining location, we are able to provide you complete magnetic solutions to upgrade your metals, minerals and your processes in magnetics.
These Intensity Magnetic Roll Separators are highly effective of magnetic separation of para magnetic particles and weakly para magnetic particles separately. These Rare Earth Magnetic roll separators are made up of very high power specially developed Nickel, Iron Boron (Nd-Fe-B) with highest magnetic power available in the series to enable us to achieve very high gauss value compared to other similar products.
Right now, we have developed latest Magnetic Roll Separators with a diameter of 150mm which gives higher magnetic force and more contact area than the normal 100mm diameter magnetic rollers. This type of Magnetic Roll is specially configured with configurations of suitable magnetic material sizes and its magnetic properties.The Magnetic Roll Separators have been passing through the belt which the material is running, is made of different type magnetic materials with different thickness to suit effective beneficiation of separating minerals and metals.
These effective magnetic roll separators can be achieved with different type of thickness of belt ranging from 0.25mm to 2mm and some of the belt material which we have been using are having a non stick property and they are highly resistant to abrasiveness. Some of the belt material are coated with Nylon for its non stick property. These belts are basically made up of Kevlar, which is a Bullet Proof material and highest strength of its kind. These STAR TRACE Magnetic Roll Separators are having several passes to make sure of highest purity can be obtained by which several magnetic process repeatedly without much material handling. These Magnetic Roller Separators are primarily used in replacement of old magnetic technology of induced magnetic roller separators.
Rare Earth Roll Magnetic Separators Working Principle:
Magnetic Roll Separators consist of two rolls, one of which is magnetics. There is a belt between them to carry the ore into the magnetic field. The movement of the belt in the Magnetic Roll Separator is controlled by a motor fixed to one of the magnetic rollers. The rotational speed of magnetic rollers can be adjusted according to the magnetic material properties and type.
The material to be processed is conveyed to the belt by magnetic vibrating feeder at a required rate. Feeding rate can be controlled by adjusting the vibration on feeder. A magnetic Roller separators blade has been set in order to be able to collect separated magnetic products in different places and to adjust the product properties in a desired manner.
Magnetic Roll Separators Operating variables are:
- Magnetic Field strength (measured indirectly and controlled by amp adjustment of the electromagnet) typically up to 15,000 gauss.
- Pole gap (closer the gap higher the field strength), typically 2mm.
- magnetic Roller speed ( normally fixed and only adjusted by pulley and belt changes).
- Splitter position (determined by visual observation of the fan).
- Feed temperature will affect magnetic susceptibility.
- Feed rate typically 2.5tph.

Rare Earth Magnetic Roll Separators Uses:
Induced Magnetic Roll Separators are primarily used for magnetic separation or concentrating minerals or materials of low magnetic susceptibility.Uses include extraction of minerals of type iron or chromium bearing minerals from silica sand, the concentration minerals such as wolframite, the removal of paramagnetic minerals such as Iron Titanium Oxide (Ilmenite, FeTiO3), Iron Carbonate (siderite, FeCO3), etc., from valuable non-magnetic minerals, and purification of dry granular chemical compounds and abrasives.These self-cleaning magnetic roll separators selectively removes magnetic components out of a conveyed material and discharges them as distinct and clean material. Field intensity is adjustable for recovery of selective type. Very high magnetic gauss of 20,000 is achieved by the magnetic roller separators.
The throughput and degree of magnetic separation depends upon the following factors:
- The susceptibility of the magnetic fraction - throughput is reduced for materials of lower magnetic susceptibility.
- The particle size - for most materials the maximum size which can be satisfactorily treated is 3mm. For the treatment of dry materials up to 50 mm in size, electromagnetic multi-channel Pulley or Drum Separators are available (details available upon request). The presence of fine particles (particularly those less than 30 microns) reduces throughput.
- The bulk density - higher magnetic values increases throughput.
- The flow characteristics - these are determined by magnetic particle shape, surface condition and moisture content. Better flow characteristics increase throughput in the Magnetic Roll Separator.
- The proportion of magnetics - a high percentage of magnetics may reduce throughput.
