Eriez Magnetic Flocculators

Compact, powerful units use magnets to speed settling of magnetic solids from slurries and liquids for easier recovery and separation.

Magnetic Flocculators



Eriez Magnetic Flocculators

Eriez Permanent Magnetic Flocculators aid in the separation of minute magnetic particles from liquids and slurries. Used widely in the iron and coal mining industries to speed settling of fine magnetic particles in ore slurries and heavy media slurries, they are finding new use in steel and other industries for agglomerating fine magnetic contaminants in quench water, cooling oils, etc.

  • Vertical or horizontal flow
  • No operating costs
  • No moving parts to wear out
  • Minimum maintenance required

Principle of Operation

Flocculation occurs when a slurry or liquid containing magnetic particles passes through the magnetic field. The fine particles become magnetized and attract each other, forming larger particles or “flocs.” These larger particles are less affected by flow turbulence and have enough mass to cause them to settle out of the slurry at a much faster rate than individual unflocculated particles.

Engineered for Specific Applications

The magnetic floculator can be engineered for any specific application. Design variables include the magnetic field strength, retention time in the magnetic field, and the overall size of the flocculator. These features allow installation on existing pipework as well as new applications.
