SGM starts off with standard circular electromagnets for lifting scrap and plates followed by new magnetic lifting solutions as more sophisticated mill applications were developed (slabs, billets, coils, multi-plates, rails, bundles of construction bars, structural, pipes ,...).
Introduction of the Electro-Permanent Lifting Magnets quickly gained the confidence and interest of their users for the greater safety they offer.
In order to meet new safety, performance and weight requirements of the oil industry for pipe lifting applications on offshore drilling platforms, SGM introduced a new generation of Rare Earth Electro-Permanent Lifting Magnets. This new technology was quickly transferred to various lifting magnet steel industry applications.
Opening of SGM Germany, SGM UK and SGM Belgium
Introduction of the first proprietary SGM Flux Measuring Device(FMD), which is a major innovation of safety measurement technology for determining the lifting force of magnets.
Opening of SGM Magnetics in Pittsburgh, USA
Introduction of the octagonal SGM Mega Scrap Lifting Magnet featuring a proprietary double magnetic circuit allowing for handling more ferrous scrap and in a more compact way than the traditional two large round magnet solution. These scrap magnets rapidly become the reference solution for the quick and gentle loading/unloading operations of railcars and are also specifically suited for belt loading with Consteel technology.
Introduction of the proprietary VHG Magnetic Circuit consisting of the use of both rare earth magnets (Neodymium ) and ferrite magnets thus combining the deep but not that strong attraction force of the Ferrite permanent magnets with the very strong but shallower attraction force of the rare earth magnets.
Introduction of the proprietary SGM Dynamic Ferrous Separators (DSRP) representing a technological evolution to the traditional magnetic pulleys resulting in the possible segregation of sellable ferrous nuggets from magnetic trash.
Introduction of the SGM Induction Sensor Based sorter (EMS) for stainless steel and copper wires present in shredder residue.
Introduction of the proprietary SGM Polishing Drum Magnets (PDM) for separating the electrical rotors (so-called “meat ball”) from a ferrous scrap stream hence reducing the copper content in ferrous scrap.
Introduction of the proprietary SGM Lifting Magnets for eye horizontal steel coils (CDMD). The CDMD measures the possible flexing and dynamic stress of those coils when handled and allows for innovative and greater safety in their handling with lifting magnets.
Opening of a second SGM subsidiary on the west coast of the USA, Los Angeles.
Introduction of the proprietary SGM lifting magnets with no side magnetic dispersion. These lifting magnets are especially suited for steel service centers where magnets can enter racks of steel bundles with no disturbing side attraction with steel columns or other bundles/packs next to the one being handled.
Opening of SGM India disposing of a mechanical shop for both production and repair.
Introduction of the proprietary SGM Eddy Current Separator TVIS spinning at 6.000 rpm provided with a titanium protection sleeve to contain the centrifuge forces of the permanent magnet blocks. Still today SGM is not only the pioneer of the high frequency ECS but, most probably, the quantity of high Frequency ECS (from 3.000 up to 6.000 rpm) supplied by SGM represents a multiple of the ones supplied by all the other brands put together.
Opening of SGM China with a demo line for the separation activity implemented in 2015
Introduction of the proprietary SGM Scrap Cleaning Line for Heavy Melt Scrap. The solution is designed to drastically reduce the about 5% non-ferrous trash present in the HMS for optimization of efficiency of the electric arc furnace.
Introduction of the proprietary SGM MIMS (Medium Intensity Magnet Separator) for the iron ore mining industry. The proprietary magnetic circuit of the SGM MIMS constitutes a true technological breakthrough to the state of the art of magnetic separators for iron ore.
Introduction of the SGM X-Ray dual energy sorter (XRS) for processing metals, heavy plastics and minerals.
Introduction of the SGM proprietary Smart Ballistic Separator (SBS) for processing Incinerated Municipal Waste (IBA). The separator allows the processing of wet IBA and the concentration of the solid pieces including the metals in a fraction larger than 2 mm and dryer than the infeed IBA. The SGM SBS represents a performing evolution of the state of the art for ballistic separators.
Introduction of the SGM proprietary Convection Electro Lifting Magnet (CELM) for hot materials. The design of the CELM drastically extends their possible duty cycles (and life time) on hot steel loads like slabs and billets. The SGM CELM constitutes revolutionary technological breakthrough innovation related to electro lifting magnets.
Opening of SGM Mexico covering all Latin America
Introduction of the SGM proprietary Convection Electro Permanent Lifting Magnet (EPCLM) for hot materials. The design of the EPCLM drastically extends their possible duty cycles (and life time) on hot steel loads like slabs and billets.
Introduction of the SGM High Resolution Color Sorter (CSS) for metals, polymers,…
Introduction of the SGM Eddy Current Separator (BVIS) designed to perform a progressive separation of the heavier finest metals.
Twentieth anniversary of Clean Magnet agency with SGM in the Republic of South Korea
Introduction of the SGM proprietary Micro Fines Process for fines shredder residue. The SGM process allows for the optimization of both recovery and purity (concentration) of metals (including precious) in fines shredder residue.
Introduction of the SGM proprietary Copper Wires Liberation Process for improving the purity of the Copper Wires recovered with induction sensor based separators from shredder residue.
Introduction of the SGM High Power Air Gravity Separation Table (PDS).
