Kneader for tooth restoration material

摘要

To mix powder and liquid components evenly, a kneader comprises a rotating plate rotated around a driving axis; a bearing for a capsule housing body mounted near a circumference part of the plate, wherein an axis supported with the bearing is rotatable only in a reverse direction to a rotating direction of the plate; a capsule housing body fixed at a capsule housing body supporting axis in parallel to the driving axis and supported with the bearing; a balance weight fixed at a predetermined position of the plate approximately opposite to the body beyond the driving axis; and a mechanism for circularly moving an axis for keeping the direction of the body in the same direction as the rotating direction of the plate along a circle having the same diameter as but the different center from those of the body supporting axis.
