I want a small system to make prestressed concrete elements. The following equipment is needed: 1. A batch concrete mixer with diesel engine, a batch mixing system with 0.50 - 1 cubic meter capacity and dosing system with 3 hoppers for cement, gravel and sand. 2. A concrete mix transferring equipment from the mixer to the extruding machine. 3. A prestressed concrete extruding machine with diesel engine, capable of prestressing and extruding 400H x 400W concrete elements like post - prestressed (400 x 400 x up to 6500mm L) and U - prestressed (400mm W x 400mm H with 2 female anchoring channels). 4. A prestressed hollow concrete extruding machine with diesel engine, capable of prestressing and extruding hollow wall panel and floor.
