High Intensity Magnetic Field Roll Separators for BIG pieces.
High Intensity Magnetic Field Roll Separators for Large Pieces
In various industrial sectors, particularly within mining, aggregates, and recycling, the efficient separation of large-sized ferromagnetic and even paramagnetic impurities is a critical challenge. Our High Intensity Magnetic Field Roll Separators are specifically engineered to tackle this demand, providing an exceptionally effective solution for processing materials where conventional magnetic separators might struggle due to the coarser nature of the particles.
Advanced Separation Technology for Coarse Materials
This product is a highly effective roll separator designed for the precise extraction of undesired materials. These can include basic iron, weakly magnetic minerals, and other contaminants, even when they are present in larger dimensions. The system excels at handling particles ranging from 20 mm to 40 mm, a size range that often proves difficult for standard magnetic separation technologies, ensuring robust and reliable separation performance.
The core of its superior performance lies in its sophisticated magnetic circuit design. After an initial triage process, the material passes over a special single-layer drum. This drum is meticulously engineered to generate an extraordinary magnetic field intensity, reaching up to 15,000 gauss directly on the drum surface. Furthermore, a consistent and powerful field of 14,000 gauss is maintained on the band that transports the material. This immense field strength is crucial for capturing and separating even weakly magnetic particles from the primary material flow, leading to a significantly cleaner end product and optimized operational efficiency.
Key Features and Operational Advantages
- Exceptional Magnetic Field Strength: Achieves 15,000 gauss on the drum and 14,000 gauss on the band for unparalleled separation capabilities.
- Optimized for Large Particles: Specifically designed to efficiently process material sizes from 20 mm to 40 mm, addressing a common industry gap.
- Robust Single-Layer Drum: Features a specially constructed single-layer drum for maximum magnetic flux density, durability, and consistent performance under heavy-duty conditions.
- Enhanced Product Purity: Ensures the effective removal of unwanted ferromagnetic and paramagnetic impurities, thereby increasing the value and quality of the processed material.
- Reliable Operation: Built with robust components to withstand the rigorous and abrasive environments typical of mining and heavy industrial applications.

This specialized Industrial High Intensity Roll Separator (Coarse Roll Separator) utilizes a massive, large-diameter roller packed with heavy Neodymium or specialized Ferrite blocks. It generates a deep, extremely powerful magnetic field designed specifically to extract large, weakly magnetic (paramagnetic) rocks, coarse ores, and heavy stainless-steel chunks from large-granule (e.g., 20mm to 100mm) bulk flows.
They are utilized in the coarse pre-concentration of weakly magnetic ores (like coarse hematite, manganese, and chromite), heavy slag processing in steel mills, and ASR (Automotive Shredder Residue) recycling to pull out heavy, crushed stainless-steel automotive parts before further shredding.
Overhead plates struggle to pull heavy, weakly magnetic pieces upward against gravity. A standard roll separator is too small and the big rocks would bounce off it. This specialized "Large-Diameter Roll" allows large rocks and heavy chunks to settle on the thick Kevlar belt. As the material cascades over the edge, the immense magnetic field holds the weakly magnetic heavy chunks just long enough to drop them into a separate waste chute.
Standard thin belts would be shredded instantly. For "BIG piece" processing, we utilize Heavy-Duty, multi-ply Kevlar (Aramid) or thick Polyurethane (PU) reinforced belts. Additionally, the feed mechanism utilizes heavy-duty vibratory pans and crash-plates (Hardox) to gently lay the heavy rocks onto the belt, eliminating high-impact drops.
Yes, they are engineered for brutal B2B mining conditions. The entire frame is constructed from heavy structural steel. The massive bearings are protected by multi-labyrinth dust seals (IP67), and the drive motors are heavy-duty, continuous-rated gearmotors designed to operate outdoors or in highly abrasive crusher environments.
While the permanent magnets cannot be turned down, the separation physics are highly adjustable. The factory operator can precisely control the belt speed via an inverter (adjusting centrifugal throw), modify the vibratory feed rate, and adjust the heavy-duty splitter blades to optimize the concentration ratio (grade vs. recovery).
Absolutely. We provide complete B2B engineering for coarse ore concentration. We can design single or multi-stage robust roll systems, perfectly matched to your primary crusher's output size (granulometry) and massive hourly tonnage requirements.
