Construction material processing

Mix different construction materials in accordance with quality requirements

The main components of the KMA 220 / KMA 220i are generously dimensioned and of heavy-duty design, enabling the plant to achieve the tremendous production rates it is capable of. The robust twin-shaft continuous mixer is undoubtedly a highlight, having a homogeneous mixing capacity of 220 tonnes per hour. The mixing blades and interior of the compulsory mixer are manufactured from highly wear-resistant material. The mixing blades allow independent adjustment and can be replaced individually. All plant components, including the mixer, are driven hydraulically via a powerful diesel engine. Benefi cial to the environment: the engine is accommodated in a sound-insulated housing. The supply of water, indispensable for any mixing plant, has also been organized in the best way possible: a permanently installed, 4,500-litre water tank guarantees continuous supply when water tanker trucks have to change.

The powerful twin-shaft compulsory mixer is equipped with specially arranged mixing arms and mixing blades made from highly wear-resistant carbide metal.

The plant can hold two different types of mineral aggregate in its large, twin-chamber proportioning hopper.
