Concrete & gravel plant Fieschertal

The crushed materials are cleaned for the first time in the washing drum and separated from unwanted components such as wood. They then enter the screening plant, where the various aggregates are extracted and another wash takes place using water. Coarse material is sieved several times, while fine material is separated off after the first sieve. The latter is then directed to the sand screw, where it goes through a last cleaning cycle. Ultimately, the granulation, as well as the mixture, have to be right. The deviation needs to be minimal to ensure that the concrete has the required properties.

The exact quantities of cement, mineral aggregates, chemical additives and water are mixed together in the twin-shaft compulsory mixer. Each type of concrete is carefully prepared according to the formula and leaves the plant in the form of fresh concrete that is immediately ready to be built with.

Plant manager Thomas Schmid has well over 10 years of experience in the production of gravel and concrete products. These days, one of his responsibilities involves supervising the plant. "In the past, everything was mechanically operated. A lot of things were done by hand, even the weighing of the individual components. These days, more and more procedures are fully or partially digital - from the management of the concrete plant to the input of the concrete formulas to quality control. I like learning new skills, and when I have a question, there is always someone here who will be able to provide the answer."
