Drum Type Magnetic Separator

Drum Type Magnetic Separators are used for Automatic separation of Magnetic Particles from Fine Powder. Drum Type Magnetic Separators are available in two designs.

Magnetic drum separators provide an efficient means for extracting ferrous material from dry, bulk products in free-flowing processing systems.

Magnetic Separators are comprised of a stationary permanent magnet, either standard Ferrite Magnets or High Power Rare Earth Magnets enclosed in a non-magnetic stainless-steel drum. Magnetic Separators diverted so that it falls onto the top and flows across the surface of the drum. Ferrous matter contained in the product flow is drawn to the drum's surface (and held against it) by the powerful magnet housed inside.

While non-ferrous products falls from the side of the drum in a normal manner, ferrous metal clings to its surface. As the portion of the drum with the ferrous material rotates to the side opposite the product flow, the magnetic field is reduced so that the ferrous matter falls from the drum into a collection container. The end result is purified product ready for processing without the worry of costly damage caused by tramp metal.

Rare Earth, Neodymium is 5 times stronger than Ceramic Magnets and can remove micron sized particles.

Drum Separators can be provided as the drum only or as a complete assembly with the housing and drive included. A variety of sizes and strengths are available for many applications.

Features :

• Drum magnets are powerful magnet assembly combined with high surface holding power.
• The magnets have greater magnetic pole area.
• Magnetic Separators require minimum space and are simple to operate.
• They are flexible enough to be applied for various purposes
• Drum magnets have steel support bearings

Specifications :

• The materials normally used for housing drum magnets are stainless steel, flanges etc.
• The magnetic materials preferred for drum magnets are either ceramic magnets or rare earth magnets.
• Magnetic Separators are available in different sizes and face width.
• Normally the drum magnets have self cleaning design.

Operating Principle :

Permanent magnetic drum is designed and manufactured in such a manner that only half of its side is magnetized. An empty stainless steel 304 shell which surrounds the magnet rotates freely. The magnet is stationary. Ferrous particles which get attracted are collected separately as shown.

Application :

The magnetic drum separator is most ideal for separation of iron particles from granules and powders. It is widely used in Glass, Ceramic, Chemical, Foundry, Fertilizer, Plastic and Food Industry.

Magnetic drums up to 600mm diameter and 1500mm length (Ferrite and Super power) can be supplied on short delivery basis. Please send details of your requirement to offer the most appropriate size for your plant.

Advantages :

• Helps in removing ferrous particles from any non ferrous powder and crystals
• Ideal for plastic, food, fertilizer, pharmaceutical, chemical, glass and continuous process plants.
• Provide utmost protection to crushers, grinders, pulverizes, and allied equipment.
• Can be used for mining and ore dressing industry.
• Eliminate fire hazards and explosions in plants dealing with explosive material.
• Saves money, time and labor by reducing beak-down time and improving the quality.

Suspension Magnet/Over band Magnetic Separators

Suspension Magnets and Over band Magnetic Separator are back bone of continuous process industry.

The permanent magnetic suspension magnets are suspended over conveyor line and are used to remove iron impurities mixed with product moving on conveyor belt. It can also be used for any other material feeding system to avoid damage to the crushers, grinders and other material handling equipments. These magnets can be made in self-cleaning design if required (Over band Magnetic Separator).

Application :

Suspension magnets and Over band Magnetic Separator find wide applications in mining, coal/power generation plant and also in chemical/ food/plastic/ ceramics industries.

Construction :

The magnetism in a permanent suspension magnet is produced by internal assembly of magnets enclosed in a non-magnetic stainless steel housing. The magnet is suspended by turnbuckle, dee shackles, wire ropes and suspended hooks.

The magnetic power in suspension magnet is designed according to material depth/belt speed of the conveyor. Operating heights up to 400 mm, are possible. The suspension magnet can also be used in conjunction with magnetic pulley to achieve 100% results.

In Over band Magnetic Separator the Conveyor belt rotates round the Permanent Magnet and iron impurities picked up are thrown off and collected separated.

Selection :

The design of magnet depends on the feed material, size and feed depth. The design also depends on width and speed of your belt conveyor.

Suspension Magnet, Over band Magnet can be introduced in existing system. Please send details of your product with sketch of existing system.

Coolant Magnetic Separators

The Coolant Magnetic Separators is designed and developed to clean the coolant liquid from very fine ferrous particles which the conventional filters cannot remove. The usages of coolant magnetic separator assures uninterrupted flow of pure coolant liquid which is very much needed for any precision grinding operation. The performance of the machine is improved for the incorporation of the coolant magnetic separator for better surface finish of the jobs.

OPERATION :

The used coolant in the grinding machine is passed through the filter to remove course sediments and then discharged into the coolant magnetic separator inlet. The coolant drum that has the permanent magnets, rotates at slow speed and in the opposite direction of the liquid flow. The fine iron particles get attracted to the strong magnetic poles present in the separator drum. A brass scrapper is attached at the other end of the machine that helps in scrapping the ferrous particles from the magnetic poles. Iron impurities get collected in the special box provided with the machine.
