• Benefits
• Operation
• Mineral Processing: Feldspar, silica sand, and high-purity quartz purification
• Ceramics: Removal of fine iron from spray-dried ceramics
• Recycling: Processing of cullet, granulated steel slag, and plastic waste
• Urban Mining: Recovering Precious Metals from E-Waste
• During operation, a dry material mixture—with particle sizes ranging from 75 microns to 15 mm—is fed as an even monolayer onto a short, narrow conveyor belt.
• As the material moves into the separation zone of the magnetic head pulley, magnetically susceptible materials are held against the roll, while non-magnetic materials continue on their normal path.
• A carefully positioned splitter then separates the two fractions: magnetically susceptible minerals and non-magnetic materials. In certain applications, it is also possible to create a third ‘middlings’ fraction consisting of weakly magnetic materials.
• The trajectories of all fractions can be controlled and adjusted by changing the speed of the conveyor belt, which is controlled by an inverter located in the main control panel.

It uses powerful neodymium magnets to effectively separate weakly magnetic materials.

Processes particles ranging in size from 75 microns to 15 mm, suitable for various applications.

It offers adjustable roll speed, splitter position, and feed rates for optimal separation efficiency.

The Rare Earth Roll Magnetic Separator (RE Roll) is at the forefront of high-intensity magnetic separation technology, offering unparalleled performance in purifying dry minerals and waste materials. This separator uses powerful neodymium-iron-boron (NdFeB) magnets to generate an ultra-strong magnetic field, capable of separating weakly magnetic materials from non-magnetic materials.

Originally developed for the ceramics and glass industries, the RE Roll has expanded its applications to include the separation of stainless steel and brass from e-waste recycling processes. It can also be used to separate anode material from cathode material in electric vehicle batteries.

The RE Roll’s specialized head pulley ensures maximum separation efficiency. This advanced technology enables the extraction of even the least magnetic minerals, such as muscovite mica and iron-stained quartz.

Applications of rare earth rolls span multiple industries:

High-Intensity Separation: The Rare Earth Roll effectively separates weakly magnetic materials from non-magnetic ones, improving product purity and value.

Adjustable Parameters: Variable roll speed, feed rate, and an adjustable splitter plate allow for fine-tuning of separation efficiency to accommodate different material characteristics.

Versatile Application: Capable of processing particles ranging from 75 microns to 15 mm, making it suitable for a wide range of industries and materials.

Efficient Design: The unique roll configuration maximizes magnetic field strength while ensuring smooth material flow and high throughput.

Customizable Options: Available in various sizes and configurations to meet specific application needs and processing capacities.
