MBZ Magnetic drum in housing
The magnetic drums are used for automatic and continuous removal of magnetic particles from bulk materials. The magnetic system based on permanent magnets is easy to operate, it reliably separates tramp metal and protects the subsequent machinery (e. g. shredders, mills, grinders) from damage. The drum separator in housing can be also equipped with a dust extraction flange for the connection to the external dust extraction system.
Design of the magnetic drum separator
The key part of the machine consists of a half-moon shaped magnetic nucleus (made from either ferrite or neodymium NdFeB magnets) and of an external drum shell from stainless steel that revolves on a shaft around the fix magnetic cores. As soon as the bulk material reaches the drum, the magnetic field attracts and holds ferrous particles to the drum shell. As the drum rotates, non-magnetic material falls freely from the stainless steel shell while ferrous particles are held firmly until they are carried out of the magnetic field.
