About MIAG GmbH
MIAG GmbH, based in Lonnerstadt (Bavaria), develops and implements machines, plants and turn-key solutions for the international milling and bulk solids industry. Its portfolio includes custom mill construction, silo and plant construction in aluminium, GRP, steel and stainless steel, pneumatic conveying systems, and turn-key project execution including installation and commissioning. The company's own MIAG product groups cover the entire process: cleaning (multi-cleaners, stone detectors, intensive dampeners), milling (roller mills, plansifters, semolina purifiers), handling, weighing technology, as well as rotary airlock valves and pipe diverters (distribution of VDL Olocco). The offering is complemented by the BoMill InSight™ grain sorting technology for single-kernel analysis. The engineering services include process design, 3D planning and plant visualization. MIAG GmbH continues the operating business of Mühlenbautechnik Bruckmann GmbH and builds on more than 30 years of experience in mill and plant construction. Customers come from the grain and milling industry, food production, bulk solids processing and fibre processing.
