Screw shafts - screw conveyor core for bulk material transport

We offer a wide range of complete screw shafts, which are an internal part of the screw conveyors. We design and manufacture them in several processes according to the latest technology and exclusively from the highest quality materials. Depending on the needs, the screw shafts are made of the core, i.e. the shaft, screw blades and pivots. They are particularly suitable for many loose materials such as cement, mud, coal, grain, pellets, eco-pea coal and sand.

Based on the dimensions given or technical documentation provided, we manufacture screws of any shape. Having many years of experience, we can offer professional advice on how to combine all necessary parameters. We strive to ensure that the screw is adapted to the transported material in terms of size and variant.
