Abstract

A mixer having a mixing pipe (1), a rotatable mixing unit (3) having back-mixing action, and a supply of the liquid colorant (4, 5) through the wall of the mixing pipe in the area of the mixing unit allows uniform mixing of liquid colorants of differing viscosities even with fixed-cycle supply of the liquid colorants. Mixing liquid colorants using this mixer allows direct dosing of the mixed liquid colorant into a plastic processing machine in the event of volumetric dosing of the employed liquid colorants.
