| 20090020461 | Screen Basket with Replaceable Profiled Bars - A screen basket with replaceable profiled bars and method of making such screen basket are described herein. The screen basket includes profiled bars evenly spaced circumferentially to form a plurality of continuous slots that covers the whole basket length.

This is achieved with an assembly that allows to insert the profiled bars, preferably consecutively sled into each aligned ring grooves in a vertical movement. The ring grooves are profiled such that there is sufficient clearance for sliding in the profiled bars. The mounting clearance is then removed radially to hold the profiled bars in place. According to an illustrative embodiment, this is achieved by squeezing an element made of compressible material, and placed between each ring pair. | 01-22-2009 |
