A Professional Sand Dry Magnetic Separator is a specialized device used to separate magnetic minerals from non-magnetic materials in dry sand or other granular mixtures. It is widely used in mining, construction, recycling, and other industries to purify materials or recover valuable magnetic components.
Key Features of a Professional Sand Dry Magnetic Separator:
1. High-Efficiency Separation – Uses strong magnetic fields to effectively separate ferrous particles (e.g., magnetite, ilmenite) from sand.
2. Dry Processing – Operates without water, making it ideal for arid regions or where water conservation is essential.
3. Adjustable Magnetic Intensity – Allows control over separation strength for different material types.
4. Durable Construction – Made with wear-resistant materials for long-term reliability.
5. Low Maintenance – Simple design with minimal moving parts reduces downtime.
6. Environmentally Friendly – No chemicals or water required, reducing environmental impact.
Applications:
– Mining & Mineral Processing: Extraction of iron ore, titanium, and other magnetic minerals from sand.
– Construction & Aggregate Industry: Removing iron contaminants from silica sand for high-quality concrete.
– Recycling & Waste Management: Recovering metals from industrial byproducts or demolition waste.
– Foundry & Glass Manufacturing: Purifying raw materials by removing magnetic impurities.
Types of Dry Magnetic Separators for Sand:
1. Permanent Magnet Drum Separator – Uses fixed magnets to attract and separate ferrous particles.
2. Induced Roll Magnetic Separator (IRMS) – Suitable for fine particle separation with adjustable magnetic fields.
3. High-Intensity Rare Earth Roll Separator (RER) – For weakly magnetic minerals (e.g., garnet, chromite).
4. Overband Magnetic Separator – Used in conveyor systems to remove tramp iron from sand.
