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.
