  • Device for aligning a cutter assembly shaft relative to a die face of an underwater pelletizer
    Patent number: 4569809
    Abstract: The alignment device or jig is utilized in aligning a shaft of a pelletizer perpendicular with a die face and includes a sensing/scraping assembly which is adapted to travel on a die face and scrape polymer drool off the die face until a scraping edge of the assembly is in constant contact with the die face during rotation of the jig on the shaft of the pelletizer. The scraping edge is mounted on the end of a rod which is spring biased toward the die face and which is axially movable in a bore in the jig and movement of the rod indicates nonperpendicularity of the shaft to the die face. After adjusting the skew of the shaft, cessation of movement of the rod in the bore in the jig will indicate a true perpendicularity of the shaft to the die face.

The discharge apparatus limits vapor losses, outlet pluggage, and downtime on the reactor. The discharge apparatus also can be operated for allowing residence time flexibility, increased catalyst yields, and improved product quality.
