ABSTRACT:
In an apparatus for building up and repairing a refractory lining of an industrial furnace, the material is centrifugally deposited by a wheel rotated by a vertical drive shaft passing through a hopper and a mixing chamber connected thereto. A shut-off bell member having a bevelled lower edge is slidably mounted on the mounting housing of the shaft for vertical movement into selected positions wherein the bevelled lower edge defines an annular gap between the hopper and the mixing chamber for permitting the granular refractory material to flow from the hopper into the chamber and the bevelled lower edge engages the conical inside wall surface of the hopper for completely closing the annular gap for interrupting the flow. The vertical movement is effected by a pneumatic motor attached to the bell member by means of a linkage and rods.
