Magnetic drum pulley are mounted at the head of the conveyor belt where the discharge occurs and remove metal pollutants from the product on the conveyor belt. It is integrated into the system for automated continuous separation and brings in the metal parts throughout the roller rotation while the cleaned product emerges. As quickly as the conveyor belt leaves the roller, the impact of the magnet diminishes and the unwanted impurities fall from the underside of the belt into a different gathering container. This type of magnet works as additional security against metal parts that have permeated deep into the product magnetic roller and were not extracted during the very first separation by a hanging magnet. This enhances the quality and purity quite of the processed product.
The industrial applications are processes with dry products such as plastics, powders, grains, wood waste, rubber, and so on.
Magnetic drum pulley are available with the needed linking shafts according to customer specs. If the consumer requests, the roller provides special features such as round surfaces that can be integrated into the design. The production of the roller in the form of a barrel has the additional advantage that the conveyor belt keeps the direction 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 likewise be supplied with a rubber finish that is glued to the surface area, which prevents the rubber conveyor belt from moving over the roller.
A magnetic drum pulley can be incorporated as part of a completely brand-new system or as a tailor-made product into existing conveyor systems. In both cases, assembly is very easy. A great deal of rollers are made of 304 SS stainless steel with strong corrosion resistance. The ferrite roller generally has a thickness 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 remove the tiniest particles from the product.
The magnetic drum pulley at the product outlet of the conveyor belt has another terrific advantage: thanks to its self-cleaning system, no or just minimal maintenance is required. The cleaned up material falls straight 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 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 required 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 better end product, the roller will be an economical option
