Drum Magnet – Principle of Operation
`
•
The drum consists of a stationary
magnet segment
and
a stainless steel non-magnetic shell
.
The drum shell is driven by a motor and resolves in the product. The magnet segment is stationary.
The Fe objects are attracted through the stainless steel shell and “stick” to the casing. The product,
which is non-magnetic, is not attracted and falls straight through to the bottom. The Fe objects are
transported to the non-magnetic part of the drum. Here the - no longer attracted - Fe objects will fall
off the drum, into the
Fe outlet
. To ensure that the Fe objects are pushed out of the powerful
magnetic field several
carriers (ribs)
are welded to the casing.
•
Raw product – contaminated with Fe – reaches the drum shell through the
product inlet
.
•
An adjustable
rubber slat
distributes the incoming raw product as close as possible towards the
drum shell. The rubber slat position can be adjusted from the device’s outside, by loosening the nuts
at the outside housing and then rotating it towards or from the magnet.
•
The filtered product leaves the device through the
product outlet
.
