About Us
KNIELE GmbH, based in Bad Buchau, Southern Germany, is a family-run medium-sized company that has been manufacturing customized mixing plants and mixer systems since 1991. Design, production, and assembly take place at our main factory; our range of services includes conical mixers (KKM), ring pan intensive mixers (ZE/ZE-X), laboratory mixers, suspension and screed mixers, as well as complete tower, step, ribbon silo, and mobile mixing plants. We manufacture products for UHPC, UHFB, and SVB, dry mortar, ready-mix concrete, foam concrete, paving stone, and 3D concrete printing applications; furthermore, KNIELE supplies the chemical, food, and pharmaceutical industries, as well as waste disposal and recycling, including nuclear waste. In addition to new plants, the company offers conversion, modernization, material flow planning, control and regulation technology, and spare parts service (Quick-Ship). A milestone is the patented KNIELE conical mixer KKM; the main factory has been continuously expanded and our own machine park is constantly being modernized.
