Drum Screen Replacement
The ThickTech rotary drum assembly consists of four (4) separate dewatering
stages. Each stage has a stainless steel woven mesh screen that wraps around the
outside of a perforated stainless steel drum. Each screen has a specific mesh size
and wire diameter to provide an open area suitable for the type of dewatering
required in each stage of the process.
With normal operation the woven mesh screen will not need to be replaced. If
replacement is required, the screen will be provided with (2) 1/8”[3 mm] and (1)
1/16”[2 mm} shim flanges. The screen is designed to be short of the full
circumference to ensure a tight fit on the drum. Using the right combination of shims
flanges the screen can be fit tight around the drum without deforming the mesh. Use
clamps to ensure proper alignment of the mounting holes of the stationary drum
flange, the screen flange and the shim flanges. (See pages 2-1A or 2-1B and 8-2)
