Abstract:
1. A system for producing composite material slabs, comprising one or more mixers ( 1 , 2 ) for mixing a material; hoppers ( 3 , 4 ) to which the material is unloaded from said one or more mixers ( 1 , 2 ); one or more extractor/conveyor belts ( 5 , 6 ) to which the material is unloaded from said hoppers ( 3 , 4 ) and which feed the material; a homogenizing disk ( 7 ) which receives the material from said extractor/conveyor belts ( 5 , 6 ), rotates about a vertical axis and feeds the material; conveyor belts ( 14 , 17 ) which receive the material from said homogenizing disk ( 7 ); a leveling hopper ( 18 ) which receives the material from the further conveyor belts ( 14 , 17 ) ( 18 ); a double-stroke belt ( 19 ) which takes the material from said leveling hopper ( 18 ) and unloads it homogeneously; an additional leveling hopper ( 20 ) which receives the homogeneously unloaded material from said double-stroke belt ( 19 ); an extracting belt ( 21 ) which takes the material from said additional leveling hopper ( 20 ) and causes as a material to distribute along a length of said extracting belt ( 21 ); an underlying leveling hopper ( 22 ) to which the material is unloaded from said extracting belt ( 21 ), wherein said extracting belt ( 21 ) is movable with said underlying leveling hopper ( 22 ) that is integral with said extracting belt ( 21 ) in an opposite direction to unload the material to an underlying mould ( 23 ) so as to cover a whole surface of the mold and to fill the mould.
