Electromagnetic Pulleys

Eriez provides the protection of a separator with a powerful uniform field over its entire surface. This field removes both large and small tramp iron from nonmagnetics traveling at various speeds in various burden depths on belt conveyers.

Electromagnetic Pulleys

These powerful Electromagnetic Pulleys are used for effective separating heavy tramp iron and fine iron contaminants from conveyor transported materials. They are ideal to help solve even the toughest iron separation problems involving high speeds, heavy burden depths and hard-to-separate materials.

Equipment Furnished:
The shaft, collector rings, brush holders with brushes and dust–resistant collector ring housing are furnished with each pulley as standard equipment. Lagging is available as an option. Only direct current is suitable for energizing electromagnetic pulleys. Standard voltage is 115V DC but other non–standard voltages can be supplied at slight additional cost. Where direct current is not available, suitable rectifiers can be supplied.

All shafts are steel and are amply proportioned to handle the required load. Shafts are carefully machined from oversize stock to required finished dimensions.

Insulation and Coils

Coils are layer–wound on cores that are designed to prevent movement of the coils. High dielectric insulating materials are used on all metal surfaces adjacent to the coils.

Collector Rings and Housing
Heavy cast bronze rings insulated by bakelite discs are used. Housing is of cast iron with a readily accessible interior.

Large carbon brushes insure positive continuous contact. The housing is equipped with grease and dustproof seals to prevent foreign matter from getting in.
