MODULAR PLANETARY CONCRETE MIXER FOR CONCRETE PRODUCTION Russian patent published in 2014 - IPC B28C5/16 B01F7/16 

FIELD: construction.

SUBSTANCE: planetary concrete mixer for production of concrete at construction sites and at manufacturing enterprises for preliminary manufacturing of building elements comprises a reservoir equipped with a reducer unit, having mixing facilities and components of their drive, and the upper central part of the fixed body has a feeding unit. The system to distribute water, cement and additives is installed on the fixed body of the reducer and comprises a set of concentric pipes, where the first extreme internal pipe is designed to supply cement, the external concentric pipe is designed to remove dust, and since it is concentric to the pipe for cement, it limits formation of cement dust, and the last extreme external concentric pipe is used to supply water. This pipe, due to a section with a conical lower edge, distributes water in the form of an umbrella water and additives flow radially along the entire surface of the reservoir via holes, arranged with even intervals, at the same time additives get into the water pipe via connections.

EFFECT: improved working characteristics.
