Collaboration between Goudsmit Magnetics and Sortatec results in a single separator for waste flows

Cooperation between Dutch company Goudsmit Magnetics of Waalre and German company Sortatechas resulted in a mobile metal separator that separates both ferrous and non-ferrous metals from bulkflows. The companies will jointly demonstrate the Goudsmit Mobile MetalXpert at the Recycling Aktivin in Karlsruhe, Germany. 

Goudsmit builds magnets for iron-free carbon black

Goudsmit recently built two magnets to be used for the production of iron-free carbon black by a large European manufacturer. These self-cleaning, rotating magnets remove iron particles as small as 30 microns from the very dry, poorly flowing conductive carbon black used for lithium-ion batteries.It is essential that this product is 100% metal-free, because metal particles would change the conductivity. In this line, the rotating magnets process at a relatively low capacity of 1500 kg per hour. If necessary, however, such magnets can process at  capacities of up to 40 m3 per hour. 

New conveyor feed boosts yield of Eddy Current Separator

The conveyor feed recently developed by Goudsmit Magnetics consists of a conveyor belt feed that is supplied by a product distributor. This prevents clogging of the vibratory chute during the recycling process and increases the yield of non-ferrous metals. Sticky or damp product streams, such as incinerator bottom ash (IBA) and refuse-derived fuel (RDF) adhere to the surface of vibratory chutes, preventing them from distributing the product evenly. The product takes on a preferred orientation (the path of least resistance) preventing formation of a homogeneous layer, which results in reduced yield of non-ferrous metals.

Updated non-stick feeder module designed to improve fine, non-ferrous separation from IBA flows

Goudsmit Magnetics of Waalre is producing a black edition of the EddyFines 38HI eddy current separator specially for IFAT 2018. This updated separator has a non-stick feeder module that further improves non-ferrous separation from IBA (Incinerator Bottom Ash) flows. For the black edition, the magnetic drum separator with vibratory feeder has been replaced by a non-stick feeder module with integrated 1800 or 3000 gauss head roller magnetic separator. Owing to the moist, cement-like product consistency of, in particular, incinerator slags, the use of a magnetic drum separator led to uneven distribution and sticking on and in the vibratory feeder trough and in the shell of the magnetic drum separator. 

Recovery of Metals from Waste

At the Recycling Aktiv, Goudsmit Magnetics will present a complete demo recovery line for the recovery of ferrous and non-ferrous metals from ASR (AutomobileShredder Residue), metals, wood, construction and demolition waste, etc. During the trade fair the material to be separated will circulate over a mobile non-ferrous separator before passing under a permanent scrap drum magnet that picks out the pieces of iron and then casts them over the top, back into the product stream. 

New overbelt magnets suitable for explosive dusty environments

At the IFAT in Munich, Goudsmit Magnetic Systems (stand C2-316) will show recently developed overbelt magnets suitable for ATEX zone 21 and 22 explosive dust environments. These magnets are suitable for removing iron particles from recycling, bulk-handling or biomass material flows such as wood, household waste, RDF (refuse-derived fuel) as well as coal or cement -- materials that are increasingly being reused and/or employed as fuel for power generation.

Strong Eddy Current Separator Increases Yields

Goudsmit Magnetic Systems BV, of Waalre, has supplemented its current line of eccentric Eddy Current separators with a mobile Eddy Current line. This installation is constructed on a trailer and proves its value in the field. The separator is equipped with the most recently developed, super-strong Eddy Current separator type NF1500/38HI and includes the largest internal magnet rotor on the market. Due to this, the magnetic force on the belt surface, the magnetic angle of influence and the magnetic field depth are considerably raised. This results in improved separation yields not only of the fine fractions < 5 mm but also of the medium-sized fractions +5 -50 fractions, in many cases up to 30% more. We refer to this as the following generation Eddy Current separators, appropriate for particles from 0.5 mm.

Adding mobility to an Eddy Current separator

Netherlands-based Goudsmit Magnetic Systems BV recently built a 1,500 mm wide Eddy Current separator (ECS) on a mobile skid. The company says these mobile separation systems are particularly suitable for local reprocessing of domestic waste incineration slag, as well as wood and rubble recycling and shredder residue.The unit’s skid frame is equipped with four hydraulic legs which allow the separator to be placed at any height up to a maximum length of two metres below the base frame. Moreover, the machine is equipped with two output conveyer belts, one for the product and one for metal. Mobile ECS SKIDs are especially useful for incineration slag, because this slag will be buffered somewhere for a period and then processed all at once on location.

I-SENS sensor separators

The I-SENS sensor separator is a recent development from Goudsmit Magnetic Systems BV. This system can be used to replace hand pickers, and is designed to supplement the separation of metals before or after an eddy current separator. The I-SENS removes metals such as stainless steel, lead and copper wire that EC separators cannot remove, as well as other metals in a given flow.  

Overbelt electro magnets

These overbelt electromagnets are designed specifically to be suitable for dusty, explosive environments and are particularly suitable for the removal of iron particles from recycling and/or bulk handling material flows such as wood, garbage, refuse derived fuel, hard coal, or cement.  These units meet stringent European ATEX Directive requirements and feature conveyor belts which are built extra strong and durable so they will easily capture separated iron particles and then cast them off.  

High gradient separator redesigned

These redesigned high gradient separator units have been specially developed for the recycling industry, and are particularly suitable for difficult and dirty work environments. With the redesign, the magnetic value of the coil has been increased to 10,000 Gauss. This allows magnetically weak iron and RFS particles, or slightly magnetized particles such as stainless steel, to be removed from waste and residual streams. Goudsmit’s standard high gradient separator was initially developed for cleaning chrome sand in foundries, as well as the removal of black specks from salt or ceramics. Specially manufactured for the recycling industry, this new High Gradient Separator is available with a swath up to a breadth of 1,500 mm, or larger on request. The complete system consists of a frame, a vibrating chute, a control unit, the high gradient separator and an easily adjustable splitter unit. For even more effective separation, a two-level model (or other custom configurations) can be manufactured. The two-level model consists of two very powerful magnetic rolls of approximately 10,000 Gauss (measured on the surface of the magnetic roll.) The high Gauss value of the high gradient magnetic roll means that normal ferrous particles are attracted with great force. According to Goudsmit, this force of attraction is so strong that belts can be damaged, and a normal magnet should be introduced as a pre-separator.

Fine fraction separator

These non-ferrous separators are designed for use in separating four to 14 mm-sized fractions from brown goods. By rotating the magnet rotor at a high speed, the alternating magnetic field increases, allowing separation of small fractions. This process uses eddy current technology and applications range from the processing of scrap to C&D and plastics.

Three-stage system

Combining a conventional magnetic separator, high-gradient separator and non-ferrous separator, this compact, three-stage machine removes normal iron parts, followed by weak magnetic metal parts (including a large variety of stainless steels), and non-ferrous metal. The three-stage separator is available with a working width of up to 2,000 mm, and the complete system consists of a base frame, a vibrating grating, a control unit, and the three-stage separator.
