Permanent Magnetic Drum Pulley

Permanent Magnet drum pulley replaces the drive pulley at the end of conveyor belts. We have a wide variety of conveyor belt types, the drum pulley are supplied made to measure and it is ready for installation. As shown in the figure that magnetic head roller extracts the iron particles from the material flow and carries them to the underside of the belt where they are removed and collected. Head roller magnets for conveyor belt are supplied in permanent magnets.

The version with permanent magnets are fitted with powerful and An-Isotropic hard ferrite magnets / Rare earth magnets system is also available in two types: with longitudinal polar field distribution for use with low levels of iron contamination and thin mineral layers, and with lateral polar field distribution for greater material thickness and larger iron particles.

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

General Specification

• Flux density: 8500 ± 200 gauss
• Maximum operating temperature 450?C
• In all pulleys, best grade St. Ferrite/Rear Earth magnets are used for construction. The outer face and the end plates of the magnetic pulley are made out of stainless steel
• The magnetic pulley removes contaminants like nuts, bolts, wire, tools etc.
• It protects equipment, and product from the hazards of tramp iron

Types

• High Intensity – (NdFeb Magnet – 8500 Gauss)
• Low Intensity - ( Ferrite Magnet - 3500 Gauss)

Customized Pulley Designs

Shree Vishwakarma Magnets also makes custom designed Magnetic Pulleys to precisely fit customer’s application. Following information is required

• Type of material
• Conveyor belt width
• Belt Speed
• Size and concentration of the contamination
• Burden depth

Installation

Installation is often very simple. Four bolts on a set of pillow block bearings normally hold the pulley in place. Loosen the conveyor belt, remove the old pulley and install the magnetized pulley. This type of installation does not require electricity.
