<p>The invention is applicable in concrete, building grout and reinforced concrete construction technology. Its object is a concrete or grout mixer of free falling type. The offered mixer contains a rotating body and internal scapulae. There are freely attached chains inside the mixer, that can be affixed to the internal surface of the body or to the mixer's scapulae. The chains could be joined by cross-chains. The application of the mixer, in comparison to known mixers of the free falling type, improves the homogeneity of the mixture, increases the mixer's productivity, ensures self-purification in the process of work and facilitates its cleaning at the end of the work.</p> |
