Abstract
Provided is a dust stop device for a sealed kneader, the device being capable of excellent supply of lubricating oil. The sealed kneader includes a pair of rotors and a supporting member. The dust stop device includes a rotating ring attached to each rotor and a stationary ring attached to the supporting member. Both the rings have respective contact surfaces which make surface contact with each other. The stationary ring has a lubricating-oil supply portion with a through-hole. A part of the through-hole, the part including a part opened in the contact surface, is a long hole extending along a circumferential direction of rotation of the rotating ring.
