Magnetic drums MB

Installation of the permanent drum magnet

The magnetic drum can be placed on the output of a conveyor belt or below a hopper (unlike the magnetic pulley the magnetic drum is not an integral part of the conveyor). It is possible to deliver the magnetic drum also in a stainless steel housing with two hoppers under the case. The non-magnetic materials fall into the first hopper and the caught metal impurities are transported on the surface of the drum and fall off beyond the magnetic axis of the drum into the second hopper.

The permanent magnetic drum is really multipurpose, it can collect small as well as big ferromagnetic parts (the dimensions of the drum and the kind of the permanent magnets can be adapted to customer's demands).

The application of ferrite magnets arranges for nearly unlimited working life, however if you need higher magnetic force we recommend that the drum is fitted with extremely powerful neodymium NdFeB magnets (especially in case of the separation of small ferromagnetic particles from materials of worse bulk properties). We deliver the magnetic drum either separately or in a stainless steel housing. If required, the housing can be also equipped with exhaust connector flanges enabling the connection of the machine to client's ventilation system (in order to draw in the separated impurities).

We can also manufacture the housing in robust manganese steel, which will extend several times the service life of the housing even in the most demanding conditions.

Possible replacement of the wear cover

When separating abrasive materials, the drum cover may wear out. Therefore, we have modified its design so that the user can replace this cover on his own.

As a result, the lifetime of the drum and thus of the entire device will be considerably extended.

Our drum magnets generate a deep and strong magnetic field, so high separation efficiency will be achieved even when the drum is fitted with these additional wear covers.

Replacement of the magnetic drum cover

The magnetic drums are designed in such a way that the wear cover replacement can be carried out through the inspection hole in the drum housing, so there is no need to pull the entire drum out.

You just replace the individual cover segments successively. It's really simple!

We can also manufacture the housing in robust manganese steel, which will extend several times the service life of the housing even in the most demanding conditions.

Magnetic strength measurement

We pride ourselves on thoroughly testing and measuring the magnetic performance of each separator.

The measurements are made in such a way that they correspond as authentically as possible to real conditions. That is why we do not measure the magnetic flux density (= magnetic induction) only in the magnetic core (as some manufacturers do in order to artificially increase the value of magnetic induction). We also measure the magnetic induction on the drum shell, i. e., at the point of contact with the processed material, what is an important piece of information for the customer.

The information on the measured values can be found in the product datasheets as well as in the section Model family.

And, of course, each supplied magnetic separator is provided with a test report comprising the measured magnetic induction values.
