Permanent magnetic separator

Comprehensive introduction of permanent magnetic separator series products

Permanent magnetic separator is a key equipment to automatically remove ferromagnetic impurities from non-magnetic materials by utilizing the strong magnetic field generated by high-performance permanent magnetic core. With advanced design, reliable performance and maintenance-free, this series of products are widely used in many industries such as coal, electric power, cement, mining, building materials, chemical industry, grain, etc. It is the necessary choice to protect the downstream crushing and grinding equipments and to improve the purity of products.

I. Product Series Overview

Core technology features

1. High performance magnetic system design

   • Composite magnetic circuit: adopts high-performance neodymium-iron-boron (NdFeB) and ferrite composite magnetic circuit optimization design, high magnetic field strength, large gradient, strong suction.

   • Magnetic field strength:

     • Suspended (CX): surface magnetic field ≥ 1200 gauss (GS)

     • Self-dumping type (RCYD): peak magnetic field ≥1500 Gauss (GS)

   • Excellent stability: special magnetic circuit sealing technology is adopted, the demagnetization rate of magnetic induction strength is <5% within 8 years, ensuring the equipment's long-lasting durability.

2. Robust mechanical structure

   • Suspension type (CX): adopts the whole welding frame, sturdy structure, can be directly suspended and installed, maintenance-free.

   • Self-unloading type (RCYD): Adopting waist drum roller design, with automatic deflection correction function, effectively preventing the unloading belt from deviating. Stainless steel scraper thoroughly removes iron parts.

3. Intelligent control system

   • Control mode: support local manual control and centralized automatic control (with the host equipment linkage start-stop) two modes.

   • Protection level: The standard protection level is IP54, applicable to general working conditions. Explosion-proof type (ExdIIBT4) is suitable for flammable and explosive environment.

Comparison of technical parameters

IV. Selection Guide

1. Suspended (CX) selection points

   • Belt width matching: the width of the iron remover should be 200-400mm larger than the belt width to ensure full coverage.

   • Magnetic pole height: the installation height (H) is usually 1.5 times the thickness of the material.

   • Typical applications: coal pre-treatment, primary selection of raw materials for building materials, grain processing, recycling of renewable resources and so on.

2. Self-discharging type (RCYD) selection points

   • Iron unloading capacity: according to the content of ferromagnetic debris to choose the right model and unloading belt speed (usually 0.8-2.5m/s adjustable ).

   • Environmental requirements: chemical industry, coal powder, dust and other flammable and explosive places, must choose explosion-proof type.

   • Typical applications: cement production line (raw material mill inlet), coal transmission system of thermal power plant, mining crushing production line, large-scale sintering plant.

V. Installation and Maintenance

• Installation specification:

  • Suspension type: the lifting angle should be ≤30°, and the height from the belt should not exceed 80% of the rated value.

  • Self-unloading type: ≥1.5m clean space should be reserved on the side of unloading iron, and the power box is ≤10m away from the equipment body.

• Maintenance points:

  • Daily inspection: remove the adsorbed iron and impurities every week; check the bolt tightness every month.

  • Regular maintenance: test the magnetic field strength once a year; replace the roller bearing grease once every 2 years for self-discharging iron remover.

VI. Industry Solution Examples

VII. Service and Commitment
