Magnetic Head Pulley for Recycling Conveyor Systems

The AstraRoll Magnetic Head Pulley for Recycling Conveyor Systems is a heavy-duty separation component engineered to transform standard belt conveyors into continuous, self-cleaning magnetic recovery units. In modern material recovery facilities (MRF), metal recycling, e-waste processing, and bulk material handling, unwanted tramp iron and ferrous debris cause severe conveyor belt punctures, crusher jams, and equipment damage downstream.

Our high-performance magnetic pulleys replace standard conveyor drive or tail head rollers at the discharge point. As bulk materials travel over the pulley, non-magnetic materials drop freely into the main discharge chute via gravity. Ferrous metals and weakly magnetic particles are tightly attracted to the pulley's outer surface and carried underneath the belt past the magnetic zone, where they safely drop into a dedicated metal collection hopper. Engineered with high-gradient permanent magnets (Neodymium/Rare-Earth or Ferrite) enclosed in a sealed, wear-resistant stainless steel shell, AstraRoll provides seamless, 24/7 automated metal separation with zero energy consumption for the magnetic field.

Primary Applications & Industry Uses

E-Waste & Scrap Metal Recycling: Separates iron, steel, and weakly magnetic stainless steel fragments from crushed electronics, shredded cars, and mixed metal scrap.

Municipal Solid Waste (MSW) & MRF Plants: Extracts ferrous cans, nails, and tramp metal from municipal garbage streams prior to optical or air sorting.

Construction & Demolition (C&D) Waste: Protects downstream crushers and shredders by removing rebar, nails, and steel hardware from crushed concrete and wood waste.

Bulk Material & Mining Handling: Purifies raw materials such as coal, glass cullet, wood chips, slag, and aggregates to prevent downstream machine contamination.

Why Choose AstraRoll's Magnetic Head Pulleys?

Ultra-High Gradient Rare-Earth Magnet Circuit：Utilizes high-coercivity Neodymium (NdFeB) magnetic circuits to generate deep, penetrating magnetic fields, ensuring high capture rates even under thick material burden depths and high belt speeds.

Continuous Self-Cleaning & Zero Power Consumption：Unlike electromagnets, our permanent magnetic core operates continuously without power consumption, heat generation, or coil burnouts, delivering continuous 24/7 metal separation.

Hermetically Sealed Stainless Steel Construction：Encased in a heavy-wall AISI 304/316 stainless steel cylinder with precision-welded end flanges, protecting the internal magnetic core from moisture, abrasive dust, and harsh outdoor weather conditions.

Custom Shaft Geometry & Precision Dynamic Balancing：Every magnetic shaft is precision-machined to match your existing conveyor pillow block bearings and drive gearboxes, dynamically balanced to ISO G2.5 standards to guarantee smooth rotational performance.
