Applications

• The SGCP grate magnet separator is designed to provide efficient separation of ferromagnetic particles in dry bulk product flows. It is part of a complete range of magnetic purification solutions designed to guarantee material purity in demanding industrial environments.
• This grate magnet separator meets the requirements of industries where material purity is essential, particularly food processing (flour, sugar, cereals, spices), but also the chemical and pharmaceutical sectors (powders, granules).
• Installed in a free-fall line, it secures production lines while ensuring consistent quality of your material. It effectively protects industrial equipment against metal contamination and helps ensure compliance with standards.
• This grate magnet separator is particularly suited to materials with a particle size below 5 mm, for which fine magnetic separation is required.

Typical industrial applications

The SGCP is used in powder transfer lines, dosing systems, silos and packaging installations. It is ideally suited to environments requiring continuous separation without production interruption, particularly in the food industry.

Operating principles

• The SGCP grate magnet separator operates with neodymium magnetic tubes arranged in grate magnets on two levels.

• The material flow enters from the top of the unit and passes through these grates in free fall. Ferromagnetic particles are attracted by the magnetic field generated by the magnets and remain held on the tubes, while the purified product continues on its way.

• The system is equipped with a pneumatically actuated cleaning device that automatically discharges contaminants into a collection bin without dismantling. This ensures efficient separation while maintaining production throughput.

Magnetic technology used

Neodymium magnets provide high magnetic intensity, enabling the capture of fine metal particles. This technology is now a benchmark for industrial magnetic equipment.

Operating recommendations

• To ensure optimum performance of the grate magnet separator, it is essential to ensure even distribution of the material over the grate magnets. A uniform flow significantly improves separation efficiency.
• The grate magnet separator must be installed on a free-fall line with controlled throughput to avoid any overload that could reduce the capture capacity for ferromagnetic particles.
• The choice of magnets must be suited to the material being processed, in particular with regard to temperature and process constraints. High-temperature versions are available for specific materials.
• Preventive maintenance is recommended: checking the pneumatic system, emptying the collection bin and inspecting the magnetic tubes. This ensures the durability of the equipment and consistent performance.

Best practices for optimising magnetic separation

Correct installation of the magnetic separator optimises separation, reduces pressure drop and ensures smooth integration into the existing process.

General specifications
