MAGNETIC PULLEYS

INTRODUCTION:

STAR TRACE's Magnetic Head Pulley provides effective way to remove ferrous contaminant from powdery, schistose and granulate material, like ore, coal, waste, sand and etc. Magnetic head Pulley is composed of 360 degree magnetic core protected by rotatable stainless steel cover and a axis of rotation. In practice, surface of Pulley will be wrapped by belt, so as material flow over it. Ferrous contaminant will be attracted at belt and be conveyed out of material. In many applications, it’s possible to replace an existing head pulley with a permanent magnetic head pulley, on a size-for- size basis. A wide range of diameters, widths, and shaft sizes are available.

DESIGN ADVANTAGE:

STAR TRACE Magnetic head pulleys are built using our exclusive flux control magnetic circuit. This design ensures continuous magnetism around the entire circumference of the pulley-no dead spots. For less critical applications, a conventional magnetic circuit design is also offered.

TYPES OF STRENGTH:

Light duty

For general use with burden depths up to 50mm. Belt speeds to 1.8m/s. Good for secondary Clean up of misc. tramp iron and fines.

Medium Duty

For general use with burden depths up to 75mm. Belt speeds to 2m/s. Used in Construction & Demolition and Material Recovery Facility.

Heavy Duty

For general use with burden depths up to 100mm. Belt speed to 2m/s. Used in Mining, Foundry, and Heavy Duty.

Features

• The Magnetic head pulleys can be installed easily at conveyor discharge.
• They give complete magnetic protection over the entire face of the pulley for removing ferrous contaminants.
• The pulleys either use ceramic magnets or powerful rare earth magnets.
• Maximum magnetic induction on the pulley's surface is selected within the range of (1000-4500).
• Optimal conditions for magnetic separation are created due to the minimized distance between material and seperator’s effective surface.
• Unique magnetic systems are composed of powerful Rare earth magnets. Magnets are thoroughly tested to ensure that the required properties are present and to guarantee long equipment life and high performance.
• Magnetic head Pulleys come in different sizes, various diameters and widths are available on request. Shaft dimensions are to customer specifications.
• Four available Hub styles, Recessed Hubs, Flush Hubs Extended Hubs, or, No Hubs.
• Removable Steel Shaft.
• Powerful Permanent Magnet Circuit.
• Straight hub with keyway.
• Taper lock on some models, call factory to verify.
• Axial/Radial/Multi pole magnetic circuit design.
• Lifetime guarantee on magnetism.
• Heavy duty all welded construction.
• Heavy duty stainless steel shell.
• Uniform depth of field on face of pulley.
• Flat or Crowned Pulley Face.
• Smooth or lagged surface.
• Precision Machined keyways.
• Taper Locks and Set Screws.
• Fixed Shaft or No Shaft.
• Offered in Rare Earth Neodymium or strontium Ferrite.

Benefits

• No operating costs.
• Prevent costly breakdowns.
• Cost effective separation for material depth.
• Excellent for secondary separation after an overhead or drum magnet.
• Increases product purity in food, chemicals, plastics, glass by removing unwanted iron.
• Protect processing equipment like crushes, grinders, pulverizers, screens and other processing equipment from ferrous metal damage.
