Plant for colouring fluid media used in e.g. mortars and finishing plaster

摘要

In a plant for colouring fluid media, a metering pump with an adjustable stroke is co-ordinated with e.g. water flow to a mixer, to which power supply is controlled accordingly. Fluid colour concentrate is extracted from its vessel by means of suction and pressure. The line carries it to an injection nozzle, where it enters the water flow under pressure. Also claimed is a process for reproducible colouration of the medium to make coloured mixtures, inks, mortar, etc..
