Abstract

The wall of a vessel in which, e.g. plaster, is mixed with water, is of rubber, so that it distorts when a crust forms sufficient to interfere with rotation of mixer, thereby causing the crust to break up and blend with the slurry. Additionally the wall of the mixer, in the region of initial contact between powder and water, may be distorted by fluid pressure applied externally at intervals in order to prevent formation of any significant crust. The appts. may be mobile, and comprise a hopper feeding an upward inclined screw conveyor, which introduces powder to the top of a parallel downward inclined screw conveyor coaxial with mixing chamber, into which water is fed, and from the bottom of which slurry is pumped.
