SHREENATH was the first to introduce indigenous High Intensity, High Gradient Magnetic Roll SeparatorFor use of dry material in indian Market. It is capable of separating a wide variety of material from diffrent industries is an effciant and economical manner. SHREENATH uses high energy Rare Earth Neodymium Permanent Magnets assembled in a proprietary configuaration to generate forces of magnetic attraction, which can be used for processing any material from ferromagnetic to weakly paramagnetic.
The exceptionally high magnetic gradient achived by the unique SHREENETH design result in extremely large separation forces, exceeding those of any electromagnetic induced Roll Separators. SHREENTH incorporates improved design features resulting from an ongoing product development philosophy combined with extrensive operational experience.

SuspendedPermanent Magnetic Overband Separatorsare designed to eliminate tramp metal from the product carried by belt, vibratory feeders or inclined planes.Over bands are mainly used to protect Machine such as Crushers, Shredders and others, to remove ferrous particles and purify products ( Industries like Foundries, Coal Mines, Cement Works, Food, Sponge Iron, Char coal, Glass, Chemical Industries and Domestic waste recycling Plants.)The permanent Magnetic Overband Separators are used when an automatic Removal of ferrous contamination is necessary. If not, fixed Permanent Suspension Magnets are more suitable.

Applications:
Five type of Separators Re designed to operate at a predetermined working gap over the conveyor : 100, 150, 200, 250 and 300mm.
Idler and drive drums will be rolled steel construction fitted with high tensiled steel shafts and mounted in self lubricated dust sealed plumber blocks. Adjuster screws would be fitted to provide tensioning take up on idler drums.

Construction:
Two U-section pieces are fixed on the Magnet by Fastening ears and are supporting bearings of Drums. Drums are equipped with shafts mounted on removable hubs. All bearings equipped with stakes for tightening the belt.
The belt is driven by a Reduction Gear Coupled to Electric Motor / Geared Motor by Vee- belts.

Magnet Unit:
The Magnet is made of High Intensity Stroncium Ferrite Magnets and is guaranteed for the Magnetic Power through out the life of installation. A Non -Magnetic Stainlesssteel Plate is provided to cover the poles of Magnet. There is no need for any electrical supply or maintenance.

Installation:
These units can be installed either inline over the terminal head pulley (Fig - 1. ), or transversal to the conveyor (Fig - 2). In both cases, it is necessary to foresee Non- Magnetic products under the Magnetic Field.
The most effective position is inline (Fig - 1) over the head pulley. The material being conveyed is in virtual Suspension and Tramp Iron is therefore more readily extracted.
Very good results are obtained by combining a Permanent Magnetic Overband with Permanent Magnetic Pulley at discharge end.

Shreenth were the first to introduce Indigenous High Intensity. High Gradient dry permanent magnetic roll separators in the Indian market. These machines which are manufactured are base on the popular Permanent roll Technology which has been used successfully in hundreds of Industrial minerals applications around the world. The machine incorporates high energy rare earth neodymium permanent magnetic roll assembly which is manufactured and assembled under proprietary specifications to generate unsurpassed magnetic field gradients. Under this high intensity magnetic field, weekly magnetic contaminants can be easily removed efficiently. The magnetic rolls can be structured to treat particle sizes ranging from 200 mesh up to 50 mm

Permanent Drum type Magnetic Separator is most useful for separating tramp iron from non magnetic material processed in bulk quantity, for the purity of end products, recovery of metal having commercial value and protection of processing plant and machinery. These are widely used in all the processing industry for separation of iron contamination from Minerals, Chemicals, Food, Flour, Plastics, Grains, Sand, Cement, Fertilizers, Abrasives, Glass, Slag, Ores, Rock, Refractory and many other products.

Triple Drum Type Magnetic Separators are available for highest purity. The material passes through the magnet three time in Triple Drum type Machine. These are widely used for separation of iron contamination from Minerals, Chemicals, Refractory and many other products. High power permanent Magnetic plate is provided at material outlet. Modern an Isotropic Permanent Magnets are used having highest coercivity and everlasting magnetic strength. Machines are available with vibrating material inlet Hopper and totally enclosed design to avoid dusting and pollution.

Salient Features:
DRUM CONSISTS OF HIGH COERCIVITY MODERN ANISOTROPIC PERMANENT MAGNETS.
STRONG & RUGGED CONSTRUCTION.
AUTOMATIC SEPARATION OF IRON IMPURITIES.
COMPLETELY ENCLOSED DESIGN TO AVOID DUSTING AND POLLUTION.

Working Principal & Magnetic System : The permanent Magnetic Drum consists of stationery permanent Magnetic assembly having uniform and everlasting Magnetic field across the entire width of the drum, which is effective over approximately half the drum circumferences as shown in fig. Drum shell made of non magnetic stainless steel revolves around the magnetic filed. As the material fed evenly from the chute falls over the drum , powerful magnetic, field attract & holds ferrous particles to the revolving shell. As the revolving shell carries the iron particles through the stationery magnetic field, the non magnetic material falls freely from the shell while ferrous particles are firmly held until carried beyond divider 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. SizeRange:The Permanent Drum Separators are available in standard drum diameters of 300 mm. 400 mm, 450 mm, 500 mm, 600 mm, 800 mm Drum width range from 300 mm to 1500 mm. Other sizes can be made as special to your requirement. the larger the diameter and width of the drum the greater is the volume of material which can be handled. Magnetic Materials :Magnetic separators are offered with two different type of magnets. Ferrite Magnet :The magnetic separator with ceramic magnet are useful for the application where free and larger iron particles are to be separated. The average magnetic intensity on the magnetic drum surface will be 1500-2000 Gauss. Rare Earth Magnet :The magnetic separator with high intensity Rare Earth Nd-Fe-B (Neodymium- Iron- Boron) magnets are useful for removing magnetic contamination with low magnetic properties and fine iron particles are to be separated. The average magnetic intensity on the drum surface will be 3500 - 5500 Gauss.

Double Drum Type Magnetic Separators are available for highest purity. The material passes through the magnet twice in Double Drum type Machine. These are widely used for separation of iron contamination from Minerals, Chemicals, Refractory and many other products. High power permanent Magnetic plate is provided at material outlet. Modern an Isotropic Permanent Magnets are used having highest coercivity and everlasting magnetic strength. Machines are available with vibrating material inlet Hopper and totally enclosed design to avoid dusting and pollution.
