ABSTRACT:
Agglomerated particle size of ceramic materials is controlled by accurate determination of the proper final point of agglomeration. A part of a suspension in a cylindrical agitating region having agitation blades is circulated through a pipe having at least one transparent portion, the suspension which flows through the transparent pipe is irradiated with a light, preferably a laser beam and the final point of agglomeration is calculated based on the change in quantity of the transmitted light and/or the change in acoustic emission generated in the agitating region, thereby to stop the agglomeration.
