Mechanical and plant engineering since 1876
Amandus Kahl GmbH & Co. KG is a mechanical and plant engineering company based in Reinbek near Hamburg with a company history dating back to 1876. The company manufactures machines and components for mechanical and thermal process engineering in a central plant certified to DIN EN ISO 9001:2015. The portfolio includes pellet presses (flat die presses), extruders, expanders, hammer mills, pan grinder mills, mixers, conditioners, dryers, cooling and dosing systems as well as process control systems such as EAPR, ESEP and DISTAMAT. Together with its subsidiary Neuhaus Neotec in Ganderkesee, the KAHL Group also develops and builds fluidized bed systems for drying, agglomeration, spray granulation, coating and microencapsulation. The plants are used in the animal feed, biomass, recycling, food, chemical and pharmaceutical industries as well as in by-product processing, and range from individual units to turnkey factories. The offering is complemented by a pilot plant for product testing, plant planning, assembly, commissioning and worldwide service with more than 900 employees in the Group.
