The Glass Fussed tanks used for the storage of fluid or loose material. The tanks are also a fundamental building element of environmental technological facilities such as waste water treatment plants (WWTP) and bio gas stations.

We are offering grinding balls. The grinding balls have been produced since 1938 when the production process based on press forging technology was initiated. In 1961 the product range was extended by rolled grinding balls. The grinding balls are produced by vítkovice cylinders a.s. Using world-class equipment achieving high quality. In 1998 the entire production process was reequipped, heat treatment technology (quenching and tempering) was added and the product range was further extended. the rolled and forged grinding balls are actually offered in the following nominal diameters: 16, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100 and 120 mm. The grinding balls of the diameters above are produced and offered in the following hardness classes: hard 59-65 hrc for diameters d16 – d50 57-64 hrc for diameters d60 - d70 55-62 hrc for diameters d80 – d100 50-60 hrc for diameter d120 medium 42-55 hrc for diameters d16 and more low 240-360 hb for diameters d16 and more and approximate chemical composition: chemical elements in % c mn si p s cr 0, 50 - 2, 00 0, 50 - 2, 00 0, 15 - 0, 70 max. 0, 035 max. 0, 035 max. 1, 50 the grinding balls are produced of materials which have undergone a long-term development in the company and are continuously advanced to improve the end-use properties and customer satisfaction. The combination of high-quality wear-resistant steel and high grinding ball hardness ensures very low wear values during grinding. The heat treatment process is described in great detail so that each grinding ball is uniformly through-hardened which enables to achieve the best mechanical properties. The achievement of accurate volume hardness values is a matter of course. In case of special requirements we can offer production and delivery of the grinding balls in other diameters and made of various material grades provided the quantity conditions are met.
