SMALL-SIZE MACHINE FOR LOOSE MATERIALS MIXING Russian patent published in 2016 - IPC A23N17/00 

FIELD: technological processes; machine building.

SUBSTANCE: invention relates to feedstuffs and other loose materials mixing devices. Machine comprises screw drum, loading device, unloading device and loading and unloading-separating devices mounted into machine. Screw drum is divided in two and more helical drums mounted in tiers, one above other and connected into single process chain in container, equipped with vibration exciter, resilient elements, loading and unloading devices. Screw drums are made of two parts rigidly connected to each other, and are made of sections throughout entire length. Every next section is turned relative to previous one by 120° to form conical shaped multiple-start helical surface. Along screw drum entire length three broken screw lines are formed. Direction of three broken helical lines below each of tiered screw drums is opposite to direction of three broken helical lines mounted above screw drum.

EFFECT: invention will allow to improve bulk materials mixing quality.
