CONCRETE MIXER OF CONTINUOUS ACTION Russian patent published in 2014 - IPC B28C5/22 

FIELD: construction.

SUBSTANCE: concrete mixer of continuous action comprises a drum with a rotation drive, facilities for loading and unloading, a drum is made along the perimeter in the form of a multiple thread helical surface with helical grooves inside the body in the form of pockets of curvilinear shape with centres of curvature of pockets of curvilinear shape of the helical surface, arranged inside the cross section of the drum, is made of three and more identical strips of rectangular shape, twisted in the longitudinal direction relative to the longitudinal axis and bent along the helical line in the transverse direction on the cylindrical holder of strips of rectangular shape, with formation of three and more inner curvilinear surfaces along the body perimeter with convex shape with centres of curvature inside the drum and formation of overlaps inside the drum in the form of helical surfaces along the entire length of the drum from the inlet to outlet hole.

EFFECT: expansion of process capabilities in a concrete mixer of continuous action.
