Slurry Roller Magnetic Separator, Suitable For Metallurgy And Mining Coal Preparation And Other Industries
As a critical solution for metal contamination in wet processes, the Slurry Magnetic Separator delivers precision and reliability. Users should collaborate with suppliers to tailor magnetic systems, automation levels, and maintenance plans based on slurry characteristics and operational needs, maximizing efficiency and cost-effectiveness.
Working Principle
The separator employs a high-intensity magnetic field to attract and isolate ferromagnetic particles from slurries. The process includes:
Slurry Input: Contaminated slurry is pumped or gravity-fed into the separator’s chamber.
Magnetic Adsorption: Ferromagnetic particles are captured by magnetic poles (e.g., rods, drums, or grids) under a gradient magnetic field generated by permanent magnets or electromagnets.
Fluid Passage: Non-magnetic components (liquids, non-metallic particles) pass through the magnetic zone and proceed to downstream processes.
Impurity Removal: Adsorbed contaminants are manually or automatically cleaned via scrapers, high-pressure water jets, or demagnetization, enabling continuous or intermittent operation.
Selection Criteria
Slurry Properties: Viscosity, solid content, particle size distribution, pH, and temperature (-20°C to 80°C).
Flow & Pressure: Select models based on capacity (e.g., 1–100 m³/h).
Purity Standards: Target iron content (e.g., ≤50 ppm).
Installation: Explosion-proof requirements, space constraints, and mobility needs.
Maintenance & Precautions
Regular Cleaning: Prevent clogging and magnetic field weakening.
Seal Inspections: Avoid slurry leaks damaging magnets or electrical parts.
Magnet Protection: Shield permanent magnets from high temperatures (NdFeB tolerates ≤80°C) and impacts.
Sensor Calibration: Verify flow and pressure sensors to ensure automated cleaning responsiveness.
