Suspended block magnets Suspended block magnets remove undesirable ferromagnetic (Fe) particles – such as iron and steel – from material flows containing relatively little Fe contamination. The magnet pulls pieces of metal out of the raw material flow and holds them in place. This results in a pure iron fraction suitable for immediate reuse (recycling). The block magnet is suitable for placement above flat or trough-shaped conveyor belts and serves to control incoming product flows or to protect machines such as shredders and sieves. When heavy metal contamination is present, it is better...

Magnetic head pulleys A magnetic head pulley separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles, such as particles from processed stainless steel, from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic pulley is built into an existing conveyor belt system as a head or tail pulley and is a cost-effective magnetic metal separator. Magnetic head pulleys require almost no maintenance. By integrating these magnets into an existing installation, you have no additional operating and energy costs....

High-gradient magnetic head pulleys This extra-powerful magnetic head pulley - the high-gradient version - has a radial magnet construction. It separates weakly magnetic and paramagnetic particles, such as stainless steel and steel alloys, up to approximately 40 mm. The high-gradient magnet is used after the separation step for the strongly magnetic ferrous metals. The HG system is suitable for small, mono-layer fractions ranging in size from 0 to 40 mm, at low capacities. The complete solution is a compact, maintenance-friendly conveyor belt system. - Magnetic field depth 10 mm. - Robust...

Magnetic drum separators Magnetic drum separators for recycling are suitable for separation of ferromagnetic (Fe) or weakly magnetic particles from a bulk material flow. Magnetic drum separators have many uses and a low overall height. This makes them suitable for many applications, even where there is no room for overbelt magnets. They can handle high volumes, because the drum rotates continuously and therefore separates and carries away pieces of ferrous metal fully automatically. To achieve good separation it is important that the material is supplied evenly. This can be achieved with a...

Overbelt magnets An overbelt magnet is suitable for removing or separating high volumes of iron or steel and is suspended above a flat or trough-shaped conveyor belt. This type of magnet is self-cleaning and continuously separates ferromagnetic particles from material flows. Cross In practice, installation at right angles to the conveyor belt is most common, because this is the simplest solution in an existing line. An additional advantage is that the pieces of ferrous metal are discharged to the side. From the logistical standpoint, this makes processing simpler. The deferrization...

Advantages - Low power consumption; just the conveyor belt motor. - Continuously self-cleaning. - Low maintenance; just belt and bearings. - Pure iron fraction. - Suitable for low and high temperatures. Characteristics - Construction near the magnet must be made of stainless steel or non-magnetic material. - Located above the conveyor belt or reversing pulley. - Maximum installation height up to 450 mm. - Relatively large and heavy. Neodymium overbelt magnets The Neoflux® overbelt magnets are made of Nd-Fe-B or Neodymium magnetic material. They are extremely powerful and very compact. An...

Electro overbelt magnets The electro overbelt magnet has the deepest holding field and is therefore the most suitable of all the overbelt magnets for the removal of ferrous materials from thick material flows. Disadvantages are the higher power consumption and higher weight compared to the permanent overbelt magnets. What makes Goudsmit electro overbelt magnets exceptional is the construction of the magnet block. Rather than the cheaper square blocks, Goudsmit has chosen to use an extended central pole. This creates what is called an 'attenuator'. This prevents the ferrous object at the end...

Non-ferrous separators (Eddy current) Eddy current separators, or non-ferrous separators, separate non-magnetic metals. They eliminate impurities from large bulk flows and/or separate non-ferrous metals for reuse. These separators have many uses. They can handle high volumes, because the conveyor belt separates and carries away non-ferrous metals continuously and fully automatically. All Goudsmit Eddy current separators are very robustly built. Just consider the following aspects: 1. All the separators are based on an eccentric design. This means that the magnet rotor rotates eccentrically...

EddyXpert The EddyXpert is the all-rounder of the Eddy current machine line. By choosing the right Eddy current magnet rotor, it can be used for many different product flows. The magnetic systems are fully interchangeable, due to the standardized outer dimensions. This makes it easy to upgrade your Eddy current separator. Flux density (Gauss)  22HI-pole Eddy current rotor (medium/fine fractions) The outer dimensions of the 22HI rotor are identical to those of the 12-pole rotor, but the magnet configuration is radically different. It has nearly twice the number of poles, and the rotor can...

EddyFines The EddyFines is the top-of-the-line machine in the Eddy current line. This non-ferrous separator is specifically designed to separate the very smallest pieces of non-ferrous metals, also referred to as ‘fines’ or the ‘fine fraction’. Because Goudsmit focuses more on magnetic power, our machines are a cut above the rest when it comes to separating HNF (heavy non-ferrous) metals. This is also confirmed in metal mix analyses, where the separation results for metals such as copper, brass, silver and gold in particular are significantly higher than for other magnet suppliers’...
