Mixer

A mixer comprising a housing into which a powdered material and a quantity of water is introduceable, a rotary disc rotatably mounted within the housing, a plurality of lower pins fixedly secured on the disc substantially vertically, and a plurality of upper pins fixedly secured on a lower surface of an upper cover of the housing, so as to admix and agitate the powdered material with the water to produce a gypsum slurry,

• wherein said upper pins are provided with a front bulged portion expanding frontward in a rotational direction of the disc, said bulged portion extending frontward in the rotational direction so as to allow the slurry to move forward along lateral surfaces of said upper pin and the lateral surfaces being joined together with each other so as to allow the slurry to smoothly rejoin together in front of said upper pins.

• wherein said lower pins are provided with a rear bulged portion expanding rearward in a rotational direction of the disc, said bulged portion extending rearward in the rotational direction so as to allow the slurry to move backward along lateral surfaces of said lower pins,
• wherein said lower pins have a pair of said lateral surfaces defining planes substantially parallel to the rotational direction of said disc, and angled surfaces inclined to said lateral surfaces at a predetermined angle to extend rearward in the rotational direction, and
• wherein the angled surfaces on both sides in pair are jointed to each other at a predetermined angle to form said rear bulged portion and allow the slurry to rejoin together behind the lower pins.
