Magnetic drum pulley are installed at the head of the conveyor belt where the discharge happens and remove metal contaminants from the product on the conveyor belt. It is incorporated into the system for automated constant separation and attracts the metal parts during the roller rotation while the cleaned up item emerges. As soon as the conveyor belt leaves the roller, the result of the magnet subsides and the unwanted impurities fall from the underside of the belt into a different gathering container. This type of magnet acts as extra security against metal parts that have penetrated deep into the product and were not extracted during the first separation by a hanging magnet. This enhances the quality and pureness very much of the processed product.
The commercial applications are procedures with dry materials such as plastics, powders, grains, wood waste, rubber, and so on.
Magnetic drum pulley are available with the required linking shafts according to client specs. If the customer requests, the roller uses special features such as spherical surfaces that can be incorporated into the design. The production of the roller in the kind of a barrel has the additional advantage that the conveyor belt keeps the direction on the roller more exactly. Particularly, this is really crucial if there is no tensioning system in the conveyor that manages the sideways motion of the belt. The roller can also be supplied with a rubber finishing that is glued to the surface area, which avoids the rubber conveyor belt from sliding over the roller.
A magnetic drum pulley can be integrated as part of an entirely brand-new system or as a custom-made product into existing conveyor systems. In both cases, assembly is extremely simple. A great deal of rollers are made of 304 SS stainless-steel with strong corrosion resistance. The ferrite roller normally has a density of 1,500 - 2,000 Gauss. The strongest unusual earth magnet for this application with high energy density has a strength of 3,500 Gauss and can remove the tiniest particles from the material.
The magnetic drum pulley at the material outlet of the conveyor belt has another excellent advantage: thanks to its self-cleaning system, no or just very little maintenance is needed. The cleaned product falls directly from the magnetic drum pulley while the metal is still held on the belt. The belt moves away from the magnetic drum pulley as soon as possible, the metal parts are released, into a waste chute. That makes the conveyor belt a self-cleaning magnet.
The stable and permanent residential or commercial properties of the magnetic drum pulley conveyor head roller indicate that no external energy source is needed for operation and the typical loss of magnetic field strength of less than 5% throughout a year is negligible (unless the roller is exposed to heat, shock or vibration). In order to guarantee a much better final result, the roller will be a cost-efficient service
