ABSTRACT:
A rotor shaft sealing mechanism for a synthetic resin kneading machine is disclosed. The rotor shaft sealing mechanism includes a reverse screw member, a gland packing and a spring loaded compression member so that the three separate sealing means may act to seal the rotor shaft and prevent leakage of material. The sliding seal surfaces are separated from the mixing chamber so that particles produced by the wear thereof can be completely prevented from getting into the mixing chamber. The sealing surfaces are constructed of dry seals which prevents oil pollution in the chamber. The gland packing and compression member are resiliently held on to the rotor shaft by a retaining member which is resiliently connected to a support.
