Title of invention
Invention discription
 The invention consists in a mixer of wet and dry mixtures used in construction, particularly plasters, mortars and glues for construction materials. The mixer is equipped with shaft with spiral, conical springs with triangular lateral outlines, where longer catheti is situated in the same plane as the mixer's rotation plane, perpendicular to the shaft axis. In comparison with existing mixing patterns, the invention's structure gives 40% smaller power demand and 40% shorter mixing time. Using autonomic spiral components in form of conical, right-angled triangular springs makes possible more efficient disintegration of the smallest mixture particles, which helps to preserve constant homogeneous structure of mixture and increases its durability (glues mainly). The invention is presented on Fig. 1 representing lateral view of the mixer, Fig. 2 shows the spiral part, and Fig. 3 shows the view from the top. Patent reservations The mixer is equipped with bottom symmetric blades (at least three) made in form of conical, spiral springs, with particular advantage of rotation shaft (1) being equipped with radial and parallel bushings in its bottom part (2) used for spiral parts assembly (3) made in form of conical spiral springs right-angle tringle shaped, the longer catheti of which are situated in the same plane as the mixer's rotation plane perpendicular to the shaft rotation plane (1) and α angle between the longer catheti and their hypotenuses is between 25 and 35°, with springs lenght between 25 and 30 diameters and travel equal 4 diamters of the wire of the wire they're made of.
