About WIMA
WIMA Wilsdruffer Maschinen- und Anlagenbau GmbH develops and manufactures machines and plants for the processing of mineral primary and secondary raw materials. The portfolio comprises screening machines (circular, linear and elliptical motion screens), water-based density separators (HDS series, ASTRO), double-shaft paddle washers, sand traps and sand classifiers, hydrocyclone units, lamella separators and belt filter presses. In addition, the company offers contract manufacturing in steel and sheet metal construction: cutting (laser, CNC flame cutting, shearing), drilling and sawing of beams, CNC bending, automated welding, blasting, rubber lining, painting and assembly. Structural steel, stainless steel and section steels are processed. Customers come from sand and gravel extraction, recycling, biomass processing and environmental technology. Production takes place in over 7,500 m² of halls at the Wilsdruff headquarters, including two paint shops and a welding robot hall. WIMA has been part of the Langenberger Innovation Group (Doppstadt Group) since 2015 and continues the mechanical engineering tradition of Bräuer Maschinen- und Anlagenbau GmbH.
