MIXER Russian patent published in 2015 - IPC B01F7/16 

FIELD: machine building.

SUBSTANCE: invention relates to devices for the loose materials mixing to average the ready batches of the loose materials having different probability distribution of the characteristic properties to obtain general series with average, uniform properties of the entire series volume, and can be used in agriculture, food, feed, chemical industry, construction materials production. Mixer of the ready batches of the loose materials contains base, vertically installed cone casing with loading and unloading branch pipes, screw conveyer installed in it inclined with possibility of rotation relatively to its axis and vertical casing axis, and rotation drive. The screw conveyer is made in form of coiled cylindrical spring working for tension-compression, its internal diameter is equal to internal diameter of the unloading branch pipe, to which the spring bottom turns are rigidly connected, the spring top turns are secured on the cylindrical flange with diameter equal to the outside diameter of the spring, the flange is installed with possibility of free rotation relatively to the axis of the screw conveyer, the screw conveyer drive shaft is made bent, at that top part of the shaft is coaxial with the cone casing, and bottom part of the shaft is at right angle to the generatrix of the cone casing.

EFFECT: invention ensures required mixture quality.
