ELEKTROMAG has been a leading manufacturer of industrial magnetic and vibrating equipment in India since 1958.

FCB is one of the leading and most diversified industrial companies in France. It is a member of the highly reputed Fives-Lille Group which had and annual turnover of over 6 billion French Francs in 1991.

ELEKTROMAG has been manufacturing and marketing a wide range of dry high intensity electro-magnetic separators such as induced roll type, cross-belt type over the last 25 years. Most of these products are still working satisfactorily at numerous customer installations all over the country.

ELEKTROMAG has now entered into technical collaboration with FCB, France to manufacture the latest state-of-the art rare-earth permanent magnetic dry high intensity magnetic separators know as " Rollap".

Belt Type

---

The key components of the belt type "Rollap" rare earth roll separators are a powerful rare earth magnetic roll which also functions as a head pulley and a thin, high-strength, abrasion resistant conveyor belt.

The product to be treated is fed to the conveyor belt by an "Elektromag-AEG" electromagnetic vibrating feeder in which the feed rate can be steplessly controlled from 0 to 100% of capacity. As the product on the belt passes over the rare-earth magnetic roll, para-magnetic particles adhere to the belt while the non-magnetic particles fall freely off the belt into the non-magnetic chute due to centrifugal force. The retained paramagnetic particles then travel to the return side of the belt where they are discharged into the middlings/ magnetic chute depending upon their magnetic susceptibility. Adjustable splitters are provided to ensure an optimum magnetic /non-magnetic split. Roll speed is variable and can be adjusted from 40 RPM to 400 RPM thereby enabling the aid of centrifugal force in separation of the magnetics and non-magnetics.

Two standard roll widths are available: 200 mm for laboratory test work and 1000mm for industrial applications, equipment capacity depends on material characteristics and will be determined by test work.

Belts of varying width, thickness and material are available and the most suitable belt will be selected depending on customers application.

Brush Type

---

The key components of the brush type "Rollap" rare earth roll separator are an adjustable flow electromagnetic vibrating feeder which feeds directly, or through a tiltable chute and a rare earth based magnet roll. The speed of the feed material is equal to the peripheral speed of the roll.

The non-magnetic fractions are ejected off the roll surface under the combined effect of centrifugal force and gravity.

The magnetic particles which adhere to the roll are recovered back by a rotary brush revolving in the same direction as the roll.

The rotor is equipped with a continuously variable speed drive system which permits to optimise the treatment according to the magnetic susceptibilities and the particle size of the products.

• Rotor equipped with "Rare earth" magnets.
• Open type magnet field in the order of 22,000 actual gauss.
• Belt type version or brush type version (for materials free from any ferromagnetic elements)
• Quick belt replacement.
• Rotor driven by variable speed gear motor.
• Adjustable-angle flaps for product separation.
• Processing for particles from 40 micro m. upto 75 mm.
• Modular design allowing to superpose several separation stages, with belt or brush.
• Optional: Low-intensity presorting with ferrite rotor.
• Rotor diameter: 76 and 102 mm depending on the product to be processed and flow rate.

Abrasives, bauxite upgrading, beach sands, ceramic raw materials, chromite ores, coal, diamond ores, glass sands, graphite, iron ore, manganese ores, PET plastics, quartz, refractory, silica minerals and several other applications.

ELEKTROMAG offers FREE preliminary test work on customers samples on its laboratory models of both Belt and Brush Type ROLLAP available at its factory in Bombay. Customers are requested to send 5-10 Kgs. of samples for each type mineral to be tested.

Note : If the mineral to be processed contains highly magnetic (ferromagnetic) particles, it would be advisable to initially process it through a low intensity magnetic drum type / or chute type separators.

ELEKTROMAG also offers other rare earth magnetic products such as rare earth plate magnets, rods, grids, drums etc. as well as wide range of Dry & Wet low intensity magnetic separators.
