A rotary joint that transfers pressurized working fluid into a rotating machine part into a rotating machine component, has a housing belonging to the stationary machine parts, a shaft that matches the rotating machine parts, at least A bushing mounted in the housing, the bushing sealingly housing and sealingly mounted within the housing, which can be radially elastically movable.

The ier surface of the bushing and the reference mask of the shaft has a relatively sliding sealing surface, and the rotary joint bushing is coected to the radial hole of the at least one axis by ring through the ring groove on the ier surface of the bushing.

The hole in order to pass through the bushing into a fluid guide in which the pressurized workpiece fluid extends into an axial direction, and the guide groove is coected to the radial hole of the shaft. The rotary joint granulator and the feed method are combined with the side feed and the center feed,Flare Fitting and the feed assembly is coected to the side feed, and the rotary joint and the granulated nozzle are in communication.

The center feed, the granulator includes granulation mechanism, transmission mechanism, granulating head, between the rotary joint between the transmission and the granulating head, the feed port of the feed assembly and the feed port of the rotary joint side .

Advantages: First, the design of the side feed hole feed structure and the central pore feed structure, avoiding the shortcomings of the central feed in the background technology, solving the problem of side feed overflow; the second is that the granulation is good, from now The granulation has a diameter of about 2mm or so, so that the quality of the product has a quality leap; the third is the unique, simple, and its working performance is stable and reliable.
