Abstract
Abstract A polymer finisher having all of the working components designed to be preassembled as a unit apart from the finisher casing and to be quickly and readily installable within or removable from the casing in an arrangement providing reduced vibration and improved thermal conditions. When the preassembled unit is slid into the casing, the remote end of the stator-supporting rail fits into a pilot hole near the remote end of the casing. The nearer end of the rail is then attached to the nearer end of the casing. The stator members are thus prevented from rotating in the assembled reaction vessel, although they are supported on the rotor during assembly and disassembly.
