Abstract: A wear-resistant refractory lining anchor comprising a plurality of metal hollow elongated members each having a plurality of through holes, a plurality of projections, a plurality of recesses or a plurality of cut and raised portions, each of the plurality of metal hollow elongated members having one end welded to a casing. The plurality of metal hollow elongated members are disposed at predetermined intervals to support a refractory material filled inside and outside the plurality of metal hollow elongated members. This anchor has low material cost, can be easily mounted on a casing, and can stably support a refractory material filled inside and outside the metal hollow elongated members.

Abstract: A cement mixture is mixed or agitated in a hopper by rotary blades and is fed through a feed duct or chute normally imparted with vibrations from a vibrator to cement mixture receiving pockets in a rotary disk. The cement mixture in the pocket brought to an unloading position is forced to be discharged through a discharge pipe under the force of the air under pressure admitted into the pocket through a blow pipe. Since the feed duct or chute is normally vibrated, even a highly viscous cement mixture containing water can be fed through the feed duct or chute into the pockets of the rotary disk in a stable manner so that the cement mixture may be prevented from bridging across the pockets of the rotary disk, thereby not dropping into them.
