ABSTRACT:
A cone dryer with swivel arm drive and sealing arrangement consists of a conic mix receptacle with an upper housing cover having in its center a drive arrangement aligned with the receptacle axis which drives the swivel arm around the receptacle axis and which also drives the mixing screw rotating on the free pivoting end of the swivel arm. A first sealing and lubricating package supplies the upper bearing of the pivot arm on the center side, and a second sealing and lubricating package supplies the bearing of the mixing screw on the swivel arm side. For the simultaneous supply of both sealing and lubricating packages, the sealing and lubricating package on the center side and the sealing and lubricating package on the swivel arm side are connected with one another via ducts, and both sealing packages are supplied with fluid via a common receiver receptacle arranged outside the mixer.
