Abstract:
A mixer has a circular housing defining a mixing area for mixing and kneading of a gypsum slurry. A rotary disc is positioned in the housing and rotated in a predetermined rotational direction. A rotary driving shaft cointegrally connected with the rotary disc and a plurality of scrapers are positioned in the mixing area. A slurry discharge port is provided on an annular wall of the housing for feeding the gypsum slurry of the mixing area onto a sheet of paper for gypsum board liner. An opening of the slurry discharge port is divided into a plurality of narrow openings, so that fluid resistance on the gypsum slurry flowing out of the mixing area is increased. An annular basal part rotates integrally with the rotary disc and an inner end portion of the scraper is fixed to the annular basal part.

Claim (Index 11):
A mixing method for gypsum slurry with use of a mixer for preparation of the gypsum slurry, the mixer having a circular housing defining a mixing area for mixing and kneading of the gypsum slurry, a rotary disc positioned in the housing and rotated in a predetermined rotational direction, a rotary driving shaft integrally connected with the rotary disc, a scraper positioned in the mixing area, and a slurry discharge port provided on the housing for feeding the gypsum slurry of the mixing area onto a production line:\n wherein an inner end portion of said scraper is positioned in a center region of said rotary disc, an outer end portion of the scraper is positioned in a peripheral zone of the disc, said slurry discharge port is positioned on an annular wall of said housing, and an opening of said slurry discharge port is divided into a plurality of narrow openings so as to increase fluid resistance on the gypsum slurry flowing out of said mixing area through said opening of the port; and wherein said rotary driving shaft extends through an upper or lower plate of said housing, and the shaft rotates said rotary disc and said scraper about a rotational axis of the shaft so that said slurry is mixed and kneaded in said mixing area and the slurry is moved toward the periphery of the mixing area by centrifugal force acting on the slurry, whereby the slurry flows out of said mixing area through said slurry discharge port.
