Magnetic drum MB

The magnetic drum is designed for the separation of metallic, magnetic parts from bulk mixtures (non-ferrous metals, plastic granulate, etc.). It is usually inserted under the hopper of the machine or behind the conveyor belt, from which the unseparated material falls onto the magnetic drum, which performs the separation itself. Its advantage is that it is not part of the conveyor belt, so its use is more versatile.

Magnetic drum design

The magnetic drum consists of an outer, stainless steel, rotating casing with a sleeve and a magnetic core fitted with ferrite magnets or very strong neodymium NdFeB magnets. These magnets create the necessary magnetic field on the surface of the drum, thanks to which the metal particles are trapped and carried beyond the drum axis. Here, demagnetisation occurs and the metals fall off spontaneously, unlike non-metallic separated material which falls off before the axis of the magnetic drum.

Possibilities of using the magnetic drum

The magnetic drum is made of stainless steel and we are able to dimension it to your requirements. The use of a magnetic drum will significantly increase the quality of the processed material. It is also suitable for use where it is necessary to protect downstream equipment from damage by metal particles.

Vibrating conveyor (vibrating feeder) in front of magnetic separator

This conveyor spreads the accumulated material on the conveyor into a uniform layer over the entire width of the belt. The material is then easier and better separated, especially when using a non-magnetic metal separator, magnetic plate, magnetic drum or magnetic roller. The vibratory conveyor is suitable for dry bulk materials. It is not suitable for fine and sticky materials. The high trough of the conveyor prevents unwanted material from falling out of the conveyor belt.

• Belt speed: The feeding speed is adjusted according to the type of material to be transported
• Drive unit: 2x vibromotor, W 20 NX, p=0,55 kW 230/400 V, 50 Hz
• Conveyor length: 1040 mm
• Transport capacity: according to the type of material to be transported

Magnetic drum in MBZ cabinet construction

For significantly easier installation of the magnetic drum, we also supply the magnetic drum including the cabinet construction. The separation principle is exactly the same as for the magnetic drum. In this version, the magnetic drum is installed in the cabinet construction and the trouble of fixing the magnetic drum is eliminated.

Advantages of cabinet construction

The material to be separated is poured into the box structure through its upper opening. The cabinet structure is terminated by two openings through which the metals and the separated material fall out separately. The diameter, length of the drum and dimensions of the cabinet structure are adapted to your requirements. The magnetic drum in a box construction is supplied including motor and gearbox and can be equipped with either ferrite magnets or significantly stronger neodymium NdFeB magnets.

Adjustable baffle that directs the flow of material into the drum.

 

Magnetic drum in cabinet construction double deck MBZD

This double-deck magnetic drum will find its application in those operations where an even higher quality of separation needs to be achieved by adding an additional magnetic drum. Another application is in minimising contamination of the captured metals by the separated material - where the highest possible purity of the separated metals needs to be achieved.

Double-deck drum design

Magnetic drums of this separator can be equipped with ferrite and very strong neodymium NdFeB magnets. It is also possible to combine them, where one magnetic drum is equipped with ferrite magnets and the other with neodymium magnets. We recommend to consult us for the selection of the appropriate type of magnets and the correct order of the drums when combining both types of magnets. Kontaktujte nás, prosím, se svou poptávkou. We will be happy to advise you.

Advantages of the magnetic drum

1. combination of drums with different magnets
2. high quality separation
3. speed control of each drum separately
4. customisation to your requirements

Using the magnetic drum

• perfect separation
• minimization of contamination of captured metals by separated material

Adaptability to your needs

You can select the speed of each drum individually. On request, we can equip the drum with sound and light signalling. As manufacturers of these devices, we will manufacture them exactly according to your requirements - we will adapt the dimensions of the separator to your technology, recommend the appropriate diameter and length of the drums and also help with the selection of the most suitable magnets.
