Magnetic drum pulley are mounted at the head of the conveyor belt where the discharge takes place and remove metal pollutants from the item on the conveyor belt. It is integrated into the system for automatic constant separation and attracts the metal parts during the roller rotation while the cleaned product emerges. As soon as the conveyor belt leaves the roller, the result of the magnet wears away and the unwanted impurities fall from the underside of the belt into a separate collecting container. This kind of magnet serves as extra security against metal parts that have penetrated deep into the item and were not extracted throughout the very first separation by a hanging magnet. This improves the quality and pureness quite of the processed material.
The industrial 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 connecting shafts according to customer specs. If the customer requests, the roller uses unique functions such magnet conveyor as spherical surfaces that can be incorporated into the design. The production of the roller in the type of a barrel has the additional advantage that the conveyor belt keeps the instructions on the roller more specifically. Especially, this is really important 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 covering that is glued to the surface area, which avoids the rubber conveyor belt from moving over the roller.
A magnetic drum pulley can be integrated as part of a totally new system or as a custom-made product into existing conveyor systems. In both cases, assembly is really easy. A great deal of rollers are made from 304 SS stainless steel with strong deterioration resistance. The ferrite roller typically has a density of 1,500 - 2,000 Gauss. The greatest unusual earth magnet for this application with high energy density has a strength of 3,500 Gauss and can get rid of the tiniest particles from the product.
The magnetic drum pulley at the material outlet of the conveyor belt has another terrific benefit: thanks to its self-cleaning system, no or only very little upkeep is needed. The cleaned up product falls straight from the magnetic drum pulley while the metal is still hung on the belt. The belt moves away from the magnetic drum pulley as quickly as possible, the metal parts are launched, 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 suggest 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 ensure a much better end product, the roller will be an affordable option
