Magnetic drum pulley are installed at the head of the conveyor belt where the discharge takes place and remove metal pollutants from the product on the conveyor belt. It is incorporated into the system for automatic 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 result of the magnet disappears and the undesired pollutants fall from the underside of the belt into a different collecting container. This type of magnet acts as additional defense against metal parts that have penetrated deep into the product and were not drawn out throughout the first separation by a hanging magnet. This improves the quality and pureness very much of the processed material.
The industrial applications are procedures with dry materials such as plastics, powders, grains, wood drum pulley waste, rubber, and so on.
Magnetic drum pulley are offered with the needed connecting shafts according to client specifications. If the client requests, the roller provides special functions such as spherical surface areas that can be integrated into the design. The production of the roller in the form of a barrel has the extra advantage that the conveyor belt keeps the direction on the roller more exactly. Particularly, this is very important if there is no tensioning system in the conveyor that manages the sideways motion of the belt. The roller can also be provided with a rubber finishing that is glued to the surface, which prevents the rubber conveyor belt from sliding over the roller.
A magnetic drum pulley can be incorporated as part of a totally brand-new system or as a customized item into existing conveyor systems. In both cases, assembly is very easy. A great deal of rollers are made from 304 SS stainless-steel with strong rust resistance. The ferrite roller normally has a density of 1,500 - 2,000 Gauss. The greatest uncommon earth magnet for this application with high energy density has a strength of 3,500 Gauss and can remove the smallest particles from the product.
The magnetic drum pulley at the material outlet of the conveyor belt has another fantastic benefit: thanks to its self-cleaning system, no or only 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 quickly as possible, the metal parts are released, into a waste chute. That makes the conveyor belt a self-cleaning magnet.
The steady and long-term properties of the magnetic drum pulley suggest that no external energy source is required for operation and the typical loss of magnetic field http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/magnetic drum strength of less than 5% throughout a year is minimal (unless the roller is exposed to heat, shock or vibration). In order to guarantee a better final product, the roller will be a cost-efficient solution
