ABSTRACT:
A fluidizing tank for granular refractory material has a porous bottom wall that is displaceable downwardly from a bottom edge of the tank in order to define a gap through which contaminating precipitated particles can fall from the tank, preferably aided by a downward slope of the porous wall. A receptacle housing the tank contains a vibratory sieve for separating the particles from the material falling from the tank so that the sieved material may be returned to the tank, preferably directly by mechanical or suction transfer from the bottom of the receptacle.
