CONCRETE MIXER OF CONTINUOUS OPERATION Russian patent published in 2015 - IPC B28C5/20 

FIELD: construction.

SUBSTANCE: concrete mixer of continuous operation comprises the cone-shaped case and loading and unloading devices, the body is wave-shaped along the perimeter and equipped with four polygonal wave-shaped lateral surfaces and four polygonal wavy lines with variable step by length of case, increasing as the flow section increases from loading to unloading. Case is manufactured from sections mounted along the perimeter, of alternately connected one equilateral trapezoid, two similar scalene trapezoids and second, smaller by height than the first one, equilateral trapezoid, the lower bases of which are equal to each other of each of the trapezoids and smaller than the upper bases, also equal inter se of all four trapezoids, with formation of square sections at the ends. Square of each subsequent section is rotated relative to the square of previous section to an angle of 90°. Each section to be attached has square sides of the lower base equal to sides of the upper base square of the previous section.

EFFECT: improved productivity in concrete mixer of continuous operation.
