some thing we have to know in regards to the magneitc drum bofore purchase it

Magnetic drum pulley are installed at the head of the conveyor belt where the discharge takes place and eliminate metal impurities from the product on the conveyor belt. It is integrated into the system for automatic continuous separation and draws in the metal parts during the roller rotation while the cleaned item emerges. As quickly as the conveyor belt leaves the roller, the effect of the magnet wears away and the undesirable impurities fall from the underside of the belt into a different collecting container. This type of magnet serves as additional protection versus 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 purity quite of the processed product.

The commercial applications are processes with dry products such as plastics, powders, grains, wood waste, rubber, and so on.

Magnetic drum pulley are offered with the required connecting shafts according to customer specs. If the customer asks for, the roller uses unique functions such as spherical surfaces that can be incorporated into the design. The production of the roller in the form of a barrel has the additional benefit that the conveyor belt keeps the instructions on the roller more specifically. Particularly, this is extremely crucial if there is no tensioning system in the conveyor that controls the sideways motion of the belt. The roller can also be provided with a rubber covering that is glued to the surface, which avoids the rubber conveyor belt from sliding over the roller.

A magnetic drum pulley can be integrated as part of a completely new system or as a personalized item into existing Magnetic Head Roller conveyor systems. In both cases, assembly is very simple. A great deal of rollers are made from 304 SS stainless-steel with strong corrosion resistance. The ferrite roller usually has a thickness of 1,500 - 2,000 Gauss. The strongest rare earth magnet for this application with high energy density has a strength of 3,500 Gauss and can eliminate the smallest particles from the product.

The magnetic drum pulley at the material outlet of the conveyor belt has another excellent benefit: thanks to its self-cleaning system, no or just minimal upkeep 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 far 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 stable and long-term residential or commercial properties of the magnetic drum pulley mean 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 minimal (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 solution
