Range of Application :Star Trace Overband Magnetic Separation and Magnets have become primary requisite in many industries for a decade. Our products are used to remove magnetic parts from non-magnetic materials for projecting crushers, mills, processing plants etc. against too much wear and damage. Our range of Overband Magnetic Separations is used for nonmagnetic bulk goods with iron contamination, for instance cleaning of foundry sand, coal and the like. These products are also applicable for recovering magnetic material from ore, steel mill slag etc.
Generally, Overband Magnetic Separations and Suspension Magnets are installed above conveyor belts, vibratory feeders or chutes because these capable to pick up ferrous metal parts from the bulk goods. In most of the cases, magnets can also be installed in an existing installation without much expense. During use of Overband Magnetic Separations and Suspension Magnets, many factors must be considered for the various applications, and it is impossible to list them all in a brochure. Each application, material and kind of conveying involves different problems.
Owing to the shape (demagnetization factor), long, bar-shaped and large iron parts can be better separated than short, cube shaped bulbous and small iron parts. The efficiency of the Overband Magnetic Separator or Suspension Magnet fully depends on the pole size, pole distance, field intensity in the conveyor burden, lines of the material to be separated. Large burden depths, large lump sizes, sticky or humid material render the separation more difficult.
Rectangular Suspended Magnets:Our company,
Star Trace has been using the most advanced technology to design the performance of their Suspended Magnets over any belt conveyor, vibratory feeder or inclined chutes. It ideally perfect for removing tramp iron in quantities where continually discharging magnetic separators are necessary. Iron is extracted against gravity from the flow of material and held firmly to the magnet face until the magnet is de-energized. The best position for installation is it an angel over the conveyor head pulley or at the discharge point of a feeder, where the material fans out and is loose.
In this position the magnet will remove more iron belt speeds looking at it cost wise. This installation provides the best tramp iron removal for the money invested. Other installations have been made with the magnet suspended parallel to and above the conveyer. In such applications it is necessary to use a stronger magnet because tramp iron must be pulled through a fairly stable bed of material. Cleaning is simple-the operator just swings the magnet away from the conveyor, turns off the current and the tramp iron drops free.
In-Line and Cross-Belt Magnetic Separators: The In-Line or Cross Belt Magnetic Separators give at continuous and automatic discharge of collected tramp iron. A cleared belt revolves around stationery rectangular electro magnet suspended over the belt. Any iron coming on the conveyor is attracted by the magnet and discharged automatically by the cleared. Rubber canvas belt has its own independent drive. This is especially desirable where the magnet removes large quantities of tramp iron and hence never requires cleaning or stopping of the main conveyor.
The in-line suspended separator automatically discharge tramp iron in the same direction as the conveyor travels installed at an angle over the material discharge, and has added advantages of removing long pieces of iron such as rods.
Electro Magnetic Separations Design: (A) Natural Air Cooled Magnets: Star Trace’s Suspension Magnets is consisted of a magnet body and the exciter coil. Cross sections, shape and size of the magnet body are specially designed for magnetic coil and power input. Thus despite compact construction, low weight and low power input, high efficiency is reached.
The magnet body is a welded steel construction of high permeability. The standard exciter coil consists of an aluminum conductor and is manufactured by using insulating materials of class 'H' and mounted into the magnet body. If specially requested we can also supply coli wound with copper conductor, the coil is covered by a non magnets plate.
Suspension lugs and one set of turn buckles and suspension rod with bull ring are normally supplied. Electric Connection is by a terminal box. The entrance for cable fixing is fitted with a suitable cable gland.
(B) Oil Cooled Magnets:We offer a wide range of Oil Cooled Suspends and Overband Magnetic Separations. These magnets are generally shorter in height and lighter in weight as compared to the equivalent Air cooled magnets. As a result, they are more economically priced.
In addition to the construction featured of the Air Cooled Magnets, these magnets are also provided with a pressure relief value, filling hole, drain plug and an oil level gurge. Furthermore, if increased magnet power is desired, a heat exchanger can be mounted on the magnet to accelerate the cooling of the oil. A 10-15% increase in magnet power is possible with this feature.
Overband Magnetic Separators made by us are consisted of an Air Cooled or Oil Cooled Suspension Magnet, supporting structure for the discharge belt with drive drum, tail drum, and 2 additional idlers where necessary. The drums, idlers are mounted on suitable self aligning bearings. A suitable geared-motor or motor coupled to gear box is used to drive the discharge belt. The discharge belt is a rubber/canvas or rubber/nylon belt with several piles and cleats. For retightening the discharge belt, the fixed axle of the tail drum is fitted with a tensioning device. We offer a wide range of standard Electro Suspension Magnets and Overband Magnetic Separations, which is perfect for belt width upto 2500 mm and operating heights upto 1100mm.
Permanent Magnet Separation Design:Our company offers Permanent Magnetic Overband Separators and Suspension Magnets, which are powered by ceramic focused -flux, Strontium Ferrite Magnets for superior coercive force. The Magnetism in this equipment is produced by an internal assembly of the above magnetic material. This assembly is enclosed in a non-magnetic housing. Our design concentrates attractive power on the surface where it is needed most. The magnetic strength of the Permanent Magnet will match that of the corresponding size of the electromagnet used for the same application.
Combination Units :- For extra protection from tramp iron
- For increased product cleaning
- For heavy duty separation applications
System1 :System 1 consists of an Overband/Suspended Magnet Separator for removing the initial iron, which is combined with a magnetic head pulley for removing even fine iron that may be trapped below.
System3 :It consists of two metal detectors one preceding the magnet and the other succeeding the magnet. The magnet will operate at low voltage just sufficient to hold the tramp iron. On receiving signal from metal detec
