Trade Journals for the Concrete Industry

K. Studer AG is an extremely renowned manufacturer of building elements made of ashlar, natural stone and concrete. Production takes place in a modern and spaciously designed plant in Frick (Aargau/Switzerland). The product range extends from standard products to custom-made products and thus meets practically all customer requirements. The concrete is produced in a mixing plant that is probably not found anywhere else in Switzerland. The plant consists of 64 silos, equipped with a wide range of facing materials in a wide variety of colours and grain sizes. The mixing plant is the heart of the entire production. It is computer-controlled and mixes the desired type and quantity at the push of a button. Thanks to this plant, almost every colour and grain size requirement of the customers can be fulfilled individually. The mixing plant was recently completely overhauled in order to meet the increasing requirements even better. Whereas three countercurrent mixers were previously in daily use, this task is now performed by two Kniele conical mixers, which produce up to 60 different recipes every day. One of the special challenges in this project was the requirement that colour changes must always be possible - without significant interruptions in concrete production. The adjustment of the plant and the running-in of the recipes for the demanding concretes were carried out by CME, the official representative of Kniele in Switzerland.
