| 摘要 |
The invention is related to a device for the continuous mixing of lightconcrete comprising density decreasing particles, concrete and water, characterised by an elongated mixing chamber ( 1 ) in which a screw ( 4 ) is rotatably arranged around the central axis ( 5 ) of the cylinder ( 1 ). The screw is provided with two parts, a first transporting screw part ( 6 ) and a second combined transporting and mixing screw part ( 7 ). At the free end of the transporting screw part ( 6 ), a first feeding device ( 13 ) for the supply of density decreasing particles is arranged, and at the transition between the two different screw parts ( 6,7 ), a second feeding device ( 14 ) for the supply of a concrete/water mixture is arranged. The density decreasing particles are transported by means of the transporting screw part ( 6 ) into the combined transporting and mixing screw part ( 7 ), in-order to be mixed therein into a homogenous mass of at least density decreasing particles, concrete and water, and wherein at the same time, the mass is output from the free end of the combined transporting and mixing screw part ( 7 ). The invention is further related to a method of continuous mixing, and the use of a combined transporting and mixing screw. |
