Magnetic Separation: State-of-the-Art

Dear Bulkoholics,

I invite operators who have some experience, good or bad, and also equipment manufacturers of this technology, to present their latest problems and achievements in this very important field.

Please also have a look at this Google Search:

Thank you for your interest in our work.

The worldwide powder and bulk solids handling and processing community will appreciate your involvement.

Nice Thread

I agree with the thread starter that metal detection and seperation is a important part of Bulk Material Handling.

I am looking after 10MMPTA Coal Handling Project and know the importance of Metal Detection and seperation specially when my coal is going to Thermal Power Plant.

I have a query which I am sure someone here will solve for sure:

In our system, we have provided a set of Metal Detectors and in between them a magnetic Seperator.

The operation philosophy is that when the initial Metal detector detects a metal It will alarm and activate the magnetic seperator feilds so that the metal is taken off from the conveyor. But, somehow if the seperator fails, then one more detector is placed after seperator to again detect metal particals. If this second detector detects any metal - it will put a cross mark on the material where metal is present and its interlock will trip the belt for removal of Metal.

The OEM of Metal detector has asked to maintain sufficient distance of not less than 6 Meters from the Magnetic seperator as there are chances of wrong alarming dur to electromagnetic fields of magnetic seperator.

What exactly the reason may be?

what if the conveyor environment doesnt have any other practical location to place the other metal detector?

Please provide innovative & practical solution for same.
