    Application & Operation

    Magnetic separators / magnetic filter automats are systems for separating ferromagnetic particles from liquid media.

    Application areas

    The main application areas are grinding, honing and lapping machines. It is often possible to integrate the magnetic separators directly into the machines.

    Operating modes:

    Decentralized media processing: To paper band filter, collection tank or tank
    Full or partial flow: Flexible operating options
    Small systems: With few liters per minute
    Central systems: With several thousand liters per minute

    Suitable media:

    EmulsionsOilsCleaning solutions

    Construction & Design

    Main components:

    Stable housing made of stainless steel (V2A or higher grade)
    Magnetic roller with high-quality permanent magnets
    Wear-resistant scraper blade made of V2A
    Drive station
    Optional with/without pre-filter

    The magnetic roller is flow-optimized and ensures an excellent balance between separation performance and flow volume.

    Operation & Influencing Factors

    Process flow:

    1
    Contaminated medium is calmed (laminar) over the entire system width and fed to the pre-filter
    2
    Medium flows through the working gap of the magnetic separator
    3
    Ferromagnetic particles are attracted by the magnetic roller
    4
    "Layer formation" also enables separation of non-magnetic particles
    5
    Separated particles are pushed over the magnetic roller onto the scraper blade
    6
    Scraper blade is mounted ascending - liquid can flow back

    Factors influencing separation performance:

    Viscosity of the medium
    Flow behavior: Laminar / Turbulent
    Flow velocity
    Shape and size of particles
    Operating temperature

    Magnetic Rollers & Special Applications

    Various magnet types for different requirements and special cases.

    Magnetic roller types

    Hard ferrite (Standard)

    Sufficient for most applications, very robust and durable.

    Proven for coarser ferromagnetic particles
    Cost-effective solution
    High service life
    High-Performance

    Neodym (NdFeB) - Rare Earth

    Significantly more powerful in terms of separation performance.

    Remanence: approx. 12,000 Gauss
    Main application areas:
    • Media with increased viscosity
    • Separation material with particle size ≤ 70 μm
    • Demanding applications

    Special case: Grinding wool

    If grinding wool or chip bundles arise from grinding operations or other factors, this must be taken into account when designing the magnetic filter automat.

    Special features:

    Chip bundles have a relatively low Fe content in relation to the total volume
    Use of a neodym magnetic roller highly recommended
    Individual testing with sample material possible

    Practical tips

    Medium discharge

    Cycling the magnetic roller is the most effective means of reducing medium discharge. Suitable intervals can be coordinated with you based on your application.

    Adhesion on the scraper blade

    If the separated particles tend to stick or adhere in connection with the medium and temperature, the scraper blade can also be executed with a steep decline (30°).
