“Firma Codogni” Sp.j. Stalowa Wola, Poland – Forged Steel Balls for Grinding Mills for Non-Ferrous Metals Mining and Heat & Power Industries with diameters of 60, 80, 90 and 100 mm and surface hardness of 58-63 HRC. The material for the production of balls is obtained in the recovery process from scrap railhead type ST90PA. Since the mid-1990s, our steel balls have been used mainly in processing plants for copper, zinc, lead and nickel ore mining, as well as in power plants and cement plants. Since the early 1990s our main domestic customer is KGHM Polska Miedź S.A. In 1999 we developed our own method of forging balls from the railhead, which allows us to manufacture high quality products at very competitive prices. In April 2019 we have been awarded the first prize in an 3rd International Innovation Competition organized in Nur-sultan, Kazakhstan.
