Permanent magnetic pulleys are ideal magnetic products used as head pulleys in belt conveyors for removing ferrous contaminants from material flow. The magnetic field of the pulley attracts the ferrous fines which are held to the belt until it reaches the underside. The separated ferrous materials pass out of the the magnetic field and are collected separately into a chute or bin. The cleaned material is discharged normally over the pulley in a vertical drop. The magnetic conveyor head pulleys are available in various sizes to meet requirements of most
conveyor system applications.
Magnetic pulleys have following features:
The magnetic pulleys can be installed easily at conveyor discharge.
They give complete magnetic protection over the entire face of the pulley for removing ferrous contaminants.
For different conveyors the magnetic pulleys of different sizes are available.
The pulleys either use ceramic magnets or powerful rare earth magnets.
Buyer before going for magnetic pulley must keep in mind the following considerations:
The width of the pulley must match with the width of your equipment.
The diameter of pulley and shaft must match the diameter of the equipment.
The pulley selected must fit into your conveyor system.
The outer face and the end plates of the magnetic pulley is made out of stainless steel.
The magnetic material is comprised either of high-density ceramic or rare earth magnets.
The magnetic pulley removes contaminants like nuts, bolts, wire, tools etc.
It protects equipment, and product from the hazards of tramp iron.
