About Stokkermill
Stokkermill (SELTEK SRL) is an Italian manufacturer founded in 2004 producing machines and complete processing plants for industrial recycling. The product range includes single-, two- and four-shaft shredders, hammer and impact mills, cable granulation plants, crushers and presses, as well as separation technology such as eddy-current, electrostatic, densimetric, magnetic and optical sorters including X-ray technology (XRF/XRT). These are used to process material streams such as copper and aluminium cables, waste electrical and electronic equipment, end-of-life vehicles, lithium batteries, photovoltaic modules, printed circuit boards, electric motors, metals and plastics. The entire value chain – technical design, rotor manufacturing, welding, surface treatment, component production, assembly and acceptance testing – remains in north-eastern Italy. More than 1000 plants are in operation in over 30 countries; a dedicated sales team serves the DACH region.
