Permanent multi roll magnetic separator VMSV

Permanent multi roll magnetic separator fitted with extra strong magnetic cylinders is used for a continuous and automatic separation of even very small and only weakly magnetic particles (for example magnetic stainless steel or some kinds of paramagnetic minerals).

This exceptionally powerful magnetic multi stage separator consists of a vibrating feeder and up to five pairs of conveyor rollers cylinders placed vertically. One of the two head pulleys is a drive roller (we also offer a version with the rotation speed regulation according to the purified material character and processing needs) and the second one is driven. It also means that one cylinder is magnetic and the other one is non-magnetic. The cylinder pairs are interconnected by very thin, but extremely durable conveyor belt made from bullet proof Kevlar or glass teflon (it is available also with non sticking nylon finishing). The ferrous particles transported on the vibrating feeder together with the material to be purified are captured by the strong permanent magnets and dragged on the surface of the pulley beyond its magnetic axis where they fall off. The purified material (it means the non-magnetic particles) falls down by the effect of gravity on the next conveyor belt (placed under the first one), where the separation process is repeated in the same way (the splitter position of the magnetic and non-magnetic material output is adjustable). The magnetic field (pole gap) reaches the height up to 10 mm (depending on the separator model) and it is therefore recommended that the layer of the material transported on the belt shall not exceed 5 mm (the best results are achieved if the height between 2 mm is not exceeded).

The high gradient magnetic roll separator is equipped with a device for a simple adjustment of the optimal tension of the conveyor belt. An integrated hopper with a vibration feeder, whose dimensions correspond exactly with the conveyor belt width, is an integral part of this special magnetic separator. The optimum material batching on the conveyor belt (up to approx. 2.5 tonnes per hour) can be pre-adjusted by means of a vibration regulator.

This rare earth roll separator is very powerful, reliable, maintenance-free, undemanding from the installation and operation point of view. We supply it in a laboratory version as well (i. e., with a reduced dimensions and replaceable rolls of 100 mm length).

Thanks to the quality of the materials used for the production of the high intensity magnetic roller (set of extra strong NdFeB magnets in combination with special steel washers and the very thin and extremely durable Kevlar conveyor belt), this top quality separator is capable to reach the value of the magnetic induction up to 21000 gauss (depending on the separator type). Such a high magnetic induction used to be achieved by only electromagnetic separators until recently. 

The permanent multi-stage magnetic separator fitted with the extra strong magnetic cylinders is intended for the most demanding industrial applications requiring a separation of the finest ferromagnetic impurities. It is used particularly in the food and pharmaceutical industry, in sand, feldspar and kaolin mining, in the e-waste recycling (for the removal of undesirable weakly magnetic stainless admixtures), in glass and ceramic industry, during mineral processing (iron ore, quartz) etc. 


Extra value added

Magnetic force (induction) generated by the extremely strong permanent magnets from rare earth ores does not let through any unwanted ferromagnetic impurities – and that is why the application options of our products are nearly unlimited (they find their use in chemical, plastic, automotive, building and pharmaceutical industries, food processing, mining etc.).

Our company goal is not only to manufacture and deliver a product, but above all to find and offer an exact solution satisfying the requirements and needs of just YOUR company. In these days of rapid changes in technology it is very difficult to keep up with the latest trends even in the field of your own activity, not to mention other industrial or foreign branches. And that is why we offer you our technical support based on our know-how and our experience. We hope that you - as well as our present clients - will also appreciate our assistance with solving problems regarding the separation of magnetic particles from your products, that we will help to protect your expensive machinery and that our solutions will make your production process even more fluent. If you are looking for a solution of a problem with separation or detection of ferromagnetic impurities in your goods, do not hesitate to contact us. We can help you.

Free magnet audit

Free magnet audit is an exceptional service thatSollau_serviceman.jpg

  • checks the function of the magnetic separator (if the tramp metal is effectively trapped)
  • examines if the magnetic separator fulfils its potential and meets application requirements
  • evaluates the effective pull, the status, the location and the cleanness of the applied magnets

During the audit, we do not only inspect your magnetic equipment, but we also

  • provide training on care and maintenance of magnetic separators
  • suggest the measures to be taken in order to improve the operating efficiency of the magnetic separation related to your products and materials
  • identify the key areas in your company where the application of magnetic separators could enhance the operating performance, reduce operating costs, purify the product or protect processing equipment from metal damages

Audits are conducted by SOLLAU specialists that - in co-operation with the client - develop an audit plan and determine priorities. During the audit, the auditor physically inspects and measures the effective strength of the magnetic separator. He also photographs and documents the state of the device. After the check is completed, the auditor issues a detailed report including the results of the effective strength findings. The inspection results are also important references for internal quality assurance and help analyse biological, chemical and physical hazards (HAACP) as well as ensure high quality production (QA).
