We bring forth a quality range of Magnetic Roll Separators in the market. Magnetic Roll Separator, offered by us, is suitable for very fine low magnetic minerals. These Magnetic Roll Separators use magnets in various sizes made up of domestically produced alloys of rare earth metals. These Magnetic Roll Separators feature automatic belt tensioning and tracking, and tool free belt change. Working PrincipleRoll Magnetic 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 is controlled by a motor fixed to one of the rolls. The rotational speed of rolls can be adjusted according to the material properties. The material to be processed is conveyed to the belt by vibrating feeder at a required rate. Feeding rate can be controlled by adjusting the vibration on feeder. A separator blade has been set in order to be able to collect separated products in different places and to adjust the product properties in a desired manner. Technical Features

• Standard 2.5, 2, 1.5, 1, 0.75, 0.5 and 0.25 meter wide magnetic roll. Also available in a laboratory scale model with readily interchangeable rolls of 100 mm length.
• Supplied with a vibrating feeder to suit the roll width.
• Simple conveyor belt tensioning and tracking system accessible at the sides of the machine.

• Pole gap (closer the gap higher the field strength), typically 2mm.
• Roll speed ( normally fixed and only adjusted by pulley and belt changes).
• Splitter position (determined by visual observation of the fan).

UsesInduced Roll Separators are primarily used for separating or concentrating minerals or materials of low magnetic susceptibility. Uses include extraction of 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 separator selectively removes magnetic components out of a conveyed material and discharges them as distinct and clean material. Field intensity is adjustable for selective recovery. Very high gauss of 20, 000 is achieved by the magnetic separator. The throughput and degree of 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 values increases throughput.
• The flow characteristics - these are determined by particle shape, surface condition and moisture content. Better flow characteristics increase throughput.
• The proportion of magnetics - a high percentage of magnetics may reduce throughput.

Wet Drum Magnetic Separators offered by us, are available in the diameters of 1200 mm and 916 mm with lengths up to 3000 mm. This Wet Drum Magnetic Separator offers enhanced metallurgical performance. It has components such as tank, drum with magnet yoke, and drive package which make it efficient. Also, these Wet Drum Magnetic Separators are available with us at competitive prices. STL's wet permanent magnetic separators are offered in sizes of dia.1200 mm and 916mm in Lengths of up to 3000mm. Three basic separator designs are available for cobbing, roughing and finishing/cleaning applications. Each type can be supplied in single drum or multiple drum stages of taco nite or magnetite and also for recovery for magnetic medium in dense media plants. The stationary magnet yoke is an assembly of strontium-ferrite permanent ceramic magnets. The rotating drum is available with optional rubber or stainless steel covers. The magnetic flux pattern will match the tank configuration for optimum performance. STL's magnetic wet separator dia 916 x 300 mm is the smallest full scale separator in the 916 series and is primarily used for pilot plant tests. The separator can be delivered in concurrent, counter current and counter rotation versions. STL's magnetic wet separator for laboratory use have drum dimensions dia. 600 x 285 mm and dia. 200 x 100 mm and are suitable for batch or continuous testing. The test results from the STL laboratory separators correspond closely to those obtained in full scale operation. STL's magnetic wet separators have been developed in close cooperation with the Swedish mining industry for treatment of magnetite. A prime consideration in its advanced engineering design has been high capacity, improved metallurgical performance and highest availability. The separator is constructed as a separate unit consisting of drum with magnet yoke, tank and drive package, all mounted on a heavy-duty frame. The design of the frame allows any number of units to be connected in series as multi-stage installation. This design offers a flexible flow sheet layout.

STAR TRACE Magnetic Drum Separator is primarily designed and manufactured as low field intensity type separator. They have an open magnetic system with the magnetic poles located in one plain. Low field intensity separator is employed for separating iron particles from bulk material whenever foreign iron disturbs the subsequent process sequences. It is also used for removing or enriching strongly magnet content of dry type minerals. Working of Permanent Magnetic Drum Separator: After the ore slurry tank into the tank after the water pipe water to the mine under the influence of mineral particles into the tank was loose state of a mine. The role of the magnetic field, magnetic mineral particles to the magnetic pole movement magnetic agglomeration occurs, and be attracted to the cylinder. The polarity of the magnetic poles along the alternating direction of cylinder rotation, and at work be fixed, due to alternating magnetic pole magnetic stirring produced the phenomenon of non-magnetic minerals in the turning off, and eventually the suction surface of the cylinder is a concentrate. Concentrate along the edge of magnetic cylinder to the weakest at the magnetic system, mineral water spray in the unloading effect of flushing water was discharged into the concentrate tank, if it is full magnetic magnetic type roller, brush type roll unloading ore is carried out with . Non-magnetic or weakly magnetic type minerals are left with the pulp slurry in the discharge groove, that is tailings.

PrincipleDrum Separators are primarily designed and manufactured as low field intensity separators. They have an open magnetic system with the magnetic poles located in one plain. Low field intensity separators are employed for separating iron particles from bulk material whenever foreign iron disturbs the subsequent process sequences. It is also used for removing or enriching strongly magnetic content of dry minerals. The most widely used application of drum separators is by deflection separation in which the bulk material is fed onto the top of the drum. This must be spread evenly over the entire width in order to ensure optimum utilisation of the drum. The use of a vibratory feeder is appropriate for feeding the material tangentially onto the drum. This operating procedure ensures minimum wear to the outer drum and guarantees constant-speed application. At normal feed speed of 0.2-0.3 m/sec. using vibratory feeders, the material is spread and distributed quickly over the drum, which rotates at a speed of 0.6-0.8 m/sec. The material is reduced to 1/3 - 1/4 of the feed layer height. On permanent drum separators rectangular magnetic blocks generally made of sintered hard ferites are radially magnetized and mounted on a soft iron plate. The magnetic drum is connected to a rigidly fixed shaft, the position of which is adjustable. The outer drum made of high-grade steel or manganese steel rotates around the axis supported on roller bearings. Construction
