The permanent Drum Separators are available in standard drum diameters of 300 mm, 400 mm & 450 mm. Drum length range from 300mm to 1200mm. Other sizes can be made as special to your requirement. The larger diameter and length of the drum the greater is the volume of material Which can be handled.nirmalmagnet industries

Working Principle & Megnetic SystemThe Permanent Magnetic Drum consists of a stationary Permanent Magnetic assembly having uniform and everlasting Magnetic field accross the entire width of drum, which is effective overapproximately half the drum circumference as shown in Fig. Drum Shell made of non Megnetic stainless steel revolves around the magnetic field. As the material fed evenly from the chute falls over the drum, powerful magnetic field attracts and holds ferrous particles to the revolving shell as the revolving shell carries the Iron particlesthrough the stationary magnetic field the non-magnetic meterials falls frelly from the shell while ferrous particles are firmly held until carried beyond devider and out of magnetic field. The strength of the permanent magnetic drum is guaranteed to be greater than corresponding electromagnetic drum, The Permanent magnets used are everlasting magnets and its strength does not diminish during normal use and can be used through out the life of the installation.

ApplicationsSeveral types of separators are developed to operate at pre determined working space over the conveyor i.e. 100, 150, 200, 250 and 300 mm. while choosing the over band, the speed of the belt, the nature of the product, its density, its granulometry and size of the particles, which have to be extracted are the main parameters to be taken into consideration.

Construction2 “U” Section pieces are fitted on the magnet by fastening ears and are supporting bearings of drums and the drum are equipped with shafts mounted on removable hubs. All the bearings are equipped with stakes for tightening the belt. Reduction gear coupled Electric Motor/Geared Motors by vee belts drives the belt.

Magnet UnitThis Magnet is developed from high Intensity Strontium Ferrite Rare Earth Magnets and guaranteed to give full magnetic power in the entire life span of installation. One Non Magnetic Stainless Steel Plate is supplied to cover the poles of the magnet. No need for electrical supply or maintenance.

InstallationThese Magnetic separator can be installed either inline over the terminal head pulley (Image-1) or traversal to the Conveyor (Image-2). For both cases, it is required to foresee Non-magnetic products under the magnetic filed. Most suitable position is inline (photo-1) over the head pulley. The material being conveyed is in virtual suspension and tramp iron is therefore more readily extracted. Good results are obtained by combining a permanent Magnetic over and with permanent Magnetic pulley at discharge end.

• Vibrating Equipment
• Conveyor System

More concerned about customer satisfaction we adopt different policies for customer care.  Each of our products is subject to strict quality control measures to ensure that only the best in terms of quality and design reaches the market.  We believe that our clients know us for the quality that we provide and are fully aware of our responsibility of catering to their needs and requirements in this regard. Half Hump Magnets:Our Half-Hump Magnets can be applied where Hump Magnets will not fit due to height restrictions. Like its full version, the Half-Hump housing directs the material flow over the single high-strength permanent magnet and breaks up aggregated material to Dis-lodge and capture the embedded metal contaminants.

Operating MethodA Short conveyor belt envelopes the Magnetic Roll and tensioning the Ideal Roll. An efficient Feeder discharges material on the Belt. The Ferro Magnetic and Para-magnetic particles adhere to the Belt while the nonmagnetic particles flow freely off the end of the Conveyor.

FeaturesMagnetic Rolls are available in 65, 75 & 100 mm dia and widths upto1200mm . There are three different Magnetic Strengths i. e. 8000 Gauss, 20, 000 Gauss and 22, 000 Gauss. The Roll is driven by a 0.5 HP, variable speed DC/AC geared Motor drive adjustable from 0 to 100 RPM. For the purpose of Feeding, Vibratory Feeder with Control is provided. The Machine is provided with Abrasion resistant endless conveyor Belts of 0.8mm thickness.

ApplicationsNirmal Machines are most suitable for various types of Industrial Minerals applications i. e. Abrasive, Refractory and Ceramic Raw Material beatification, Alumina, Silica, Carbide, Magnetic, Quartzite, etc. Glass Raw Materials, Clean Silica Sand, quartz, Feldspar, Dolomite etc., Ultra High Purity Quartz Cleaning, Graphite Upgrading, Manganese Orebenification, Bauxite Upgrading, Diamond ore benification, Selective Separation of Garnet / Ilmenite/Rutile, Zircon, Benification of Iron ore, Recovery of Metals from Slag, Removal of Ferro Silicate from Limestone, Megnesite etc.
