The automatic above-the-flow chute plate magnetic separator DND-SFX

Self-cleaning above-the-flow chute plate magnetic separator / Flush face plate magnet with automatic cleaning / Automatic hump magnet

The automatic above-the-flow chute plate magnetic separator is a unique solution for the separation of ferrous particles from dry or semi-liquid materials.

This automatic separator is used in above-the-flow chute or belt applications where the ferrous contaminants are captured by powerful permanent magnets and automatically carried away by a stripper plate into the side waste hoppers. The cleaning intervals of the magnetic plate can be individually preset according to the type of product being cleaned and the contamination degree. The flush face plate magnet with automatic cleaning is equipped with very strong neodymium magnets (NdFeB) allowing for the most efficient separation of magnetic particles.

The basic elements of the automatic above-the-flow chute plate magnetic separator consist of a self-supporting structure with a stripper plate, strong permanent magnets, a stainless steel chute and waste hoppers (for the removed ferromagnetic impurities). The magnetic plate is suspended above the stainless steel chute (or above a conveyor belt where applicable) and magnetic particles contained in the streaming material are continuously attracted to the stripper plate (equipped on the upper side with powerful permanent magnets). The caught magnetic impurities are then - at preset intervals -transported by the stripper plate into the waste hoppers, and the clean material moves on the chute (or on the conveyor) for further processing. The automatic cleaning is carried out by pneumatic cylinders (moving the stripper pan) and managed by a pre-programmed control unit. The compact DIN 1.4301 stainless steel structure provides for a simple and easy installation into the already existing production lines and at the same time guarantees high resistance and a long working life of the whole system.

Thanks to the entirely unique design, the self-cleaning above-the-flow chute magnetic separator allows for automatic recovery without production stoppage, i. e., no undesirable shutdowns occur. Another indisputable advantage is the fact that the material being cleaned is in direct contact with neither the magnetic cores nor the stripper plate. Therefore, not even high abrasiveness of the processed material can result into the damage of the magnetic separator or into the threat to operational continuity. That is why the automatic above-the-flow chute plate magnetic separator represents a well-balanced alternative to expensive trunnion magnet separators and rotary trommel screens which are used in particular to clean materials coming out of ball mills (in the course of cement production, ore processing,  coal crushing in thermal electric stations, foam glass manufacturing 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).
