SCREEN FRAME MAINTENANCE
Action Frequency
Inspect float mounts for excessive sag (greater than 1 inch / 25.4 mm)
and/or signs of deterioration or damage. If excessive sag is found,
clean excess buildup of process material from screen frame to reduce
loading on float mounts. If excessive sag remains, or damage is
evident, float mounts must be replaced. Note that mounts at discharge
end must be replaced as a pair (top and bottom).
Monthly or as
required
Inspect front curtain and rear feeder seal for signs of deterioration or
damage (Figure 5-1). The rear feeder seal prevents feed slurry from
entering the hopper at the feed end, while the front curtain prevents
solids from entering the hopper at the discharge end. Replace front
curtain and/or rear feeder seal if function is compromised.
Monthly
Check compression and condition of screen panels. Panels should be
in complete contact with the screen frame bed and should not have
holes or other damage that would allow solids to pass through. Replace
damaged screen panel(s).
Each shift
Inspect side supports, cross supports, and single and double bulkhead
protectors for deterioration or damage. Defective components may
permit damage to the screen panels. Refer to appropriate drawing in
Section 8 for replacement parts information.
Each screen panel
change
Inspect screen compression system components (refer to Section 6) for
signs of deterioration or damage. The screen compression components
compress the screen panels to secure them against the bed of the
screen frame. Improper screen panel compression will reduce the life of
the screen panels. Refer to Section 6 for operation and repair parts.

Perform routine maintenance on vibrator motors as described in
