Drum Type Magnetic Separators

A magnetic drum with close dense magnetic field is assembled on non-magnetic SS shaft. Magnetic pole shoes are projected out to form “fins”, for better magnetic field alignment around the drum. The drum is rotated very slowly by a geared motor drive.
A non-magnetic SS trough holds the dirty fluid close to drum. Magnetic dirt is picked-up by magnetic field & is attached to the finned drum.
Slow rotary motion dumps the dirt collected on closely contoured scrapers. Extended scraper dumps the dirt collected to a bin.
Size & number of fins is selected depending on the flow of fluid, viscosity of fluid & quantum of dirt to be handled. Positive rake scraper is selected for volatile fluid like water based emulsion while negative rake scraping is selected for oils. Negative rake scraper keeps the fluid away from bin.

Advantages:
• This is very simple separation device to separate magnetic dirt from metal working fluids.
• Absence of consumables makes it more attractive for a verity of uses.
