Multi-drum magnetic separators VMBZ
Double and triple magnetic drum / High gradient magnetic separator / Double and triple rotating drum magnet / Double and triple type magnetic separator
The multi-drum magnetic separator is a device for automatic and permanent removal of magnetic contaminants from loose mixtures. The magnetic system composed of several drums simplifies and speeds up the capture of undesirable ferromagnetic contaminants (including weak magnetic stainless steel), allows for automatic separation without production stoppage and assures the highest purity of the clean material. At the same time, the magnetic drum protects the following machinery (crushers, mills, etc.) processing the purified material from damage. The heart of the magnetic drum consists of magnetic cores (made from either ferrite or neodymium NdFeB magnets) in the shape of crescent around which the stainless steel drum rotates. The strong permanent magnets capture and drag the ferromagnetic impurities on the surface of the rotating drums. The ferrous pieces fall off beyond the magnetic axis of the upper drum, the purified material is poured onto the drum located below where the separation process is repeated in the same manner.
SOLLAU 5 year warranty
We can vouch for the quality of our magnetic separators and that is why why we provide a 5 year warranty on them! Our magnetic separators can be relied on! We are a specialist in the field of magnetic separation.
Installation of the multi stage magnetic drum
The double or triple drum magnetic separator can be placed at 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 also 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, whereas 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 VMBZ is assembled from two (DMBZ) or three (TMBZ) magnetic drums arranged one above the other — the cleaned material cascades from the upper drum to the lower one, where the separation cycle is repeated, achieving maximum capture efficiency even with heavily contaminated material. The standard MBZ drum operates with a single stage and is suitable when a single-pass separation is sufficient for the application.
We install the VMBZ beneath a belt conveyor or beneath a hopper — unlike a magnetic roller, the drum is not part of the belt but functions as a self-contained enclosed unit. The housing has two outlets: non-metallic material exits through the first, while captured metal impurities are collected separately in the second.
The VMBZ separator can be fitted with ferrite or neodymium magnets, or a combination of both across different stages — this flexibility allows the magnetic field to be tailored to the specific type and size of contamination. We advise on the most suitable configuration for your material individually, based on your line parameters.
Yes — when separating abrasive materials, the worn cover sleeve can be replaced through an inspection opening in the housing without dismantling the entire drum. Please indicate this requirement when enquiring so that we can adapt the design accordingly.
VMBZ drums are used primarily in recycling and waste processing, the ceramics and glass industry, the chemical industry, plastics and rubber processing, and the food industry — wherever maximum purity of the output material is required. They protect downstream equipment such as shredders and mills from damage caused by metal impurities.
We provide a 5-year warranty on VMBZ multi-stage magnetic drums and cover both warranty and post-warranty service. Every delivery includes on-site installation, commissioning and operator training; we also carry out free material tests on our equipment with a guaranteed turnaround of three days.
