ABSTRACT:
Spiral-shaped screw blades disposed one on another on the bottom of a mixing container are rotated at a high speed for agitating pulverulent materials including aggregate and water to form a mixture. A rapid current of the mixture of the pulverulent materials and water is brought about by the rotating screw blades and causes the aggregate in the mixture to serve as a mixing agitator like milling balls used in a ball mill, to thereby effectively break up lumps of the pulverulent material which are immiscible with water and which are inevitably formed by initially mixing the pulverulent material with water.
