45 OCW 30 oil cooled Electro Magnetic Crossbelt. Suitable for use over a 900mm (35.43”) wide belt, with a product depth of less than 150mm (5.91”). The Crossbelt produces in excess of 480 Gauss at suggested operating gap of 250mm (9.84”). Full set of guards provided to prevent access to magnet and belt when in operation. Also features continuously rated oil immersed transformer rectifier to convert the 460V, 3Ph, 60Hz AC supply to the necessary DC current required for magnet operation.

Bunting Magnetics Co. Crossbelt Design Features:


Magnet System: Specially designed by computer to maximize efficiency, is made up of a mild steel core wound with Nomex covered aluminum wire. The magnet system is totally immersed in oil to ensure maximum heat dissipation and minimum temperature rise. Special ducts in the winding allow the oil to circulate within the windings and therefore allow greater heat dissipation compared to other magnet designs. Insulation is above class ‘H’. Magnet system is mounted onto a heavy-duty back plate and enclosed with thick steel side poles to provide optimum magnetic power directed at product stream and protected with an 8mm thick manganese base plate to reduce impact damage.
Cooling: Mineral based transformer oil to BS148:1998, Class 1 and IEC 296/1982 for both magnet and transformer.
Expansion Tank: Fitted to the magnet at high level, incorporating filler, breather and oil level sight glass.
Discharge System (Electric): A shaft mounted worm geared motor unit, fitted with electric motor, drives the 3-ply rubber belt with 5 and 1.5mm covers, fitted with vulcanized wiper strips to enable efficient material discharge
Guarding: Mild steel mesh guards fitted to topside of magnet and enclosing bottom pulleys to prevent access to the belt when in operation.
Crowned pulleys: To reduce tracking issues with the belt.
Substantial Framework: Welded construction provided with eyebolts for customer’s suspension slings.
Finish: All steel will have one coat primer and two coats of RAL 5019 high performance alkyd enamel.

Transformer Design Features:


Transformer: Double wound transformer to BS EN 60076 in a fully welded steel enclosure to IP65, with bolted lid for access to oil and components. Oil level gauge fitted to front of tank and drain plug provided for oil change.
Terminals: Incoming AC and outgoing DC terminals are located in the terminal chamber on the front of the tank. Taps are located inside chamber to change outgoing DC voltage by ± 5%.
Rectifier: Silicon diode, full wave bridge connected rectifier, stack mounted on an aluminum heat sink to BS 4417 ABCD.
Protection: Diode protection with fast acting semi-conductor fuses. Surge suppression fitted to protect diodes against surges from magnet coil upon switch off.
Finish: Epoxy powder coated blue finish.
