Abstract (en)
[origin: EP0925892A1] A vertical, tubular mixer barrel has a central axial rotating shaft extending down its full length from a top mounted drive (17), and coupled at the bottom end to the spiral rotor of a vertically arranged progressing cavity pump (4). Dry mortar is fed from a hopper (3) into the upper section (1.1) of the mixer barrel and undergoes preliminary dry mixing, to ensure homogeneity, under the action of a combination screw and paddle flights attached to the shaft. The plug of dry mortar passes down the barrel and a controlled flow of water is added through an inlet (1.3) and the mortar undergoes mixing the wet section (1.3) before entering the progressing cavity section (4) to be pumped through a finishing mixer (5) and discharged via a hose (6). Liquid colorant, from a container (12) is either sucked into the mixer water feed via a venturi device (7) or into the progressing cavity pump via a bore (4.2) in the stator casing (4.1).
