Beschreibung
Zusammenfassung:	A concrete mixer for preparation of concrete mixtures of high quality and solutions of varied density includes a casing (1) in which a vertical driveshaft (16) with mixers (8, 9) is placed. Each of the mixers (8, 9) is shaped like a container which along its entire length bears a screw-wound metal wire (14). The mixers (8, 9) are fixed to a rotationally crosspiece (2) which is connected with a coupling (3) to a geared motor (4). The mixers (8, 9) are placed at different distances from the rotational centre of the cross piece (2). In a design form of the concrete mixer according to the invention the containers have the form of a ledge (15) connected to the drive shaft (16) via an arm (17) and poles (18, 19), wherein the screw wound metal wire (14) is driven through and fixed in holes (13) positioned along the entire length of the ledge (15). Each second, third, and so on of the screw-wound metal thread's (14) winding wraps can be fixed to the containers. The screw-wound metal thread's winding wraps can be interchangeably side-shifted relative to one another.
