HI Overbelt Magnetic Separator
All Bakker Magnetics products have the robust build needed survive the harshest separation environments. The machines are under constant development to ensure they continue to meet the increasingly higher demands of the recycling market. ‘Here, too, the requirements of our customers are leading,’ says Ibo. ‘They often have a specific need that we translate into a product modification – or even an entirely new machine – using high-quality magnet technology and smart engineering. We recently developed a High Intensity Overbelt Magnetic Separator, for instance, in which very powerful neodymium magnets are lined up with bucking magnets in a Halbach array. As a result, the overbelt magnetic separator has a much more powerful and deeper magnetic field, enabling it to attract small metal particles from greater distances. Processors can therefore maintain the same speed and capacity of supply while having the assurance that even the smallest metal fraction will be removed from the product.’
Stainless Steel Separator
Another product that has put Bakker at the forefront is the latest High Intensity Drum Magnetic Separator, also called a Stainless Steel Separator. Ibo: ‘In the world of recycling, stainless steel causes a real headache. And it’s all the more painful now that China has closed its market for non-separated metal recovery. Processors now have no choice but to separate stainless steel. And we have the machine to do it. Better still, our machine does it better than any other machine in the market. First of all, that’s because our magnet roll has a large diameter. This means that the stainless steel particle remains on the magnet longer which prevents it from escaping. In addition, our machine features wear-resistant, manganese steel housing protecting the drum so that it lasts eight times longer. We developed this machine in conjunction with a Belgian chipboard factory, where it performs with great success.’
Sand and fines
Ibo mentions two final “stars of the show”: ‘Our latest Wet Drum Magnetic Separator for the processing of contaminated soil. We developed an eccentric magnet configuration that enables the magnets to collect metal particles from a wet sand supply in more evenly. This prevents the machine from becoming congested all the time. Furthermore, the magnet configuration is easily set. What also deserves mentioning here is our latest Eddy Current machine; the ECS 104X. This eccentric non-ferrous separator has 104 ultra-powerful BM52 magnets in a Halbach array and a large 460 mm rotor turning at 3,600 rpm. This helps us achieve a frequency of no less than 1.56 kHz. The advantage? The working range is 0.05 seconds. It enables us to separate fines measuring just 0 – 4 mm. Moreover, the machine has a length of four metres, allowing the non-ferrous particles sufficient time to settle.’
The very best result
Our new machines and per-project customisations clearly prove that the customers’ needs really matter to Bakker Magnetics. Upon request, the company even delivers a whole range of non-magnetic components for machines worldwide that customers can fit themselves in the event that urgent repairs are required. ‘Or we supply a spare rotor, for example, to ensure that the customer’s process need never shut down. It’s always about what the customer wants: the very best result. And we at Bakker Magnetics, create machines that achieve that result,’ Ibo concludes.
