  • Patent number: 9358510
    Abstract: A planetary mixer includes frame-shaped blades configured to undergo planetary motion within a tank having a generally cylindrical inner surface and a plate-shaped bottom surface including corners formed with a curved face throughout an entire circumference of the bottom surface. Each of the blades has a vertical side portion extending along the inner surface of the tank and a bottom side portion extending along the bottom surface of the tank and connected at generally right angles to lower ends of the vertical side portion to form blade corners each formed with a curved face.
    Type: Grant

  • Patent number: 9346027
    Abstract: A planetary mixer has stirring blades that undergo planetary motion within a tank in close proximity to an inner wall of the tank for stirring solid/liquid type treatment materials received by the tank. Each of the stirring blades includes a vertical side portion having two slope faces slanting toward the inner wall of the tank, an edge face connecting outward front ends of the slope faces, and an inner face connecting inward front ends of the slope faces. The outward front ends are disposed closer to the tank inner wall than are the inward front ends, with a distance between the inward front ends being greater than a distance between the outward front ends. The inner face is formed in the shape of an arc having a center located at an intersection of a line interconnecting the inward front ends and centerline running through a center of the edge face.

  • Publication number: 20150231579
    Abstract: A planetary mixer which is used for production steps of various products in chemistry, medical treatment, electronics, ceramics, medicines, foods, feed and the like, and in which flame-shaped stirring blades are allowed to perform planetary motion in a tank, by which solid/liquid type treatment materials are subjected to stirring, blending, mixing/kneading, kneading or the like and it is intended to prevent adhesion of materials to a vertical side portion of the flame-shaped stirring blades. The vertical side portion 22 of the frame-shaped stirring blades 20 is constituted to have a cross-sectional configuration which has two slope faces 25, 26 slanting toward an inner wall of the tank, an edge face 29 connecting outward front ends 28 of the slope faces, and an arcuate inner face 30 connecting inward front ends 27 of the slope faces.
