Mixing and stirring device, method, and method for manufacturing lightweight gypsum board, including chute with eccentric orifice passage
Turning motion of gypsum slurry spouting onto a sheet of paper for a gypsum board liner is restricted for preventing maldistribution, deviation or irregular dispersion from occurring in the density distribution of the slurry on the sheet of paper. A mixing and stirring device for gypsum slurry has a circular casing forming a mixing area, a rotary disc positioned in the casing, and a tubular passage for feeding the slurry onto the sheet of paper for the gypsum board liner. A chute has a fluid passage portion with its cross section being non-axisymmetric with respect to a center axis of the tubular passage, or a fluid passage portion varying a position of the center axis of the tubular passage by a change or lateralization of the cross section of fluid passage.
