The MAGQUIP PERMAPULLEY is a range of standard permanent magnetic head pulleys for integration into conveyor belt systems acting as both the head/drive pulley as well as continuously separating metal, tramp iron and any ferromagnetic/paramagnetic minerals.
Magnetic head pulleys can provide high separation efficiency coupled with ease of installation and maintenance, with very low capital and ownership costs. This is why magnetic head pulleys remain one of the most popular types of magnetic separators.
Occupying no more space than standard drive pulleys and when being integrated into existing systems using conventional drive pulley size standards, they can be considered truly “plug and play” separators.
The MAGQUIP PERMAPULLEY range complies with standard belt conveyor drive pulley dimensions.
The magnet elements available are: Axial (transverse) pole type and radial steel pole type
In Standard Diameters from 200 mm to 500 mm, there is the option of strontium ferrite (SrFe) or rare earth (NdFeB). Permanent magnets pulley diameters 630 mm and 800 mm only available with SrFe permanent magnets.
Pulleys with ceramic ferrite permanent magnets are used for general tramp iron removal, with rare earth permanent magnets being used for more difficult fine size tramp iron removal or for applications which require stronger magnetic force such as the removal of paramagnetic material such as banded ironstone from diamondiferous gravels or the recovery of charge chrome from slag-chrome mixtures.
The pulleys are of a robust mechanical construction with shaft steel EN8 end plates mild steel shell AISI 304 stainless steel lagging 6 mm or 10 mm diamond back rubber.
The shaft is attached to the magnet element and the end plates with Bikon or similar locking devices. The shaft’s external dimensions are made to suit client’s choice of plummer block bearings and gearmotor.
