Magnetic Roller Separator for Mineral Powders

Fine mineral powders can present different separation challenges compared with coarse mineral particles.
Fine particles may have:
Different flow behaviour
Higher surface area
Greater tendency to adhere to surfaces
Different particle-to-particle interactions
Greater sensitivity to feed distribution
Therefore, a magnetic roller separator for mineral powders should be designed with attention to both magnetic and mechanical factors.
Important parameters include:
Powder particle size
Feed rate
Bulk density
Moisture
Flowability
Magnetic particle size
Material-layer thickness
Belt surface
Splitter geometry
For fine mineral powders, uniform feeding can be particularly important.
