METHOD OF CELLULAR MATERIALS, ITEMS AND STRUCTURES PRODUCTION AND RELATED DEVICE Russian patent published in 2009 - IPC B28B1/50 

FIELD: construction.

SUBSTANCE: invention relates to construction items production. Method of cellular materials, items and structures production includes mixing initial components of materials and metal beads, additional mechanical mixing of moulding compound and injecting compressed air into the above compound. Later, the compound is supplied to a screw extruder, where adobe beam is extruded from die channel. Finally beads are extruded. At the same time beam is cut to separate elements, vacuumed and thermally treated. Beads are extruded by pulse magnetic fields when adobe beam is moved at frequency of 100 Hz or more while beads are retained on electric magnets under permanent magnet field. In carrying out this method, related device is used comprising mixer with hopper to receive initial components and metal beads, which is connected to high-speed mixing machine. The said machine includes tank provided with nozzle to release compressed air. The above tank is also connected with perforated mixing machine bottom to inlet air. The high-speed mixing machine is linked with screw extruder reservoir containing die to extrude adobe beam with metal beads on the belt of ribbed transporter. Parallel endless belts with electromagnet links, electric pulse generator and cutoff knife are installed perpendicular to the transporter at a given altitude.

EFFECT: increased cellular content in items and reduced weight of items.
