AWD OPERATION
A spring-loaded plunger and reversible pawl provides a ratcheting action during movement of the
operating handle. A full 180 degrees of movement is possible in both directions. Depending on
pawl setting, moving the handle in one direction turns the jack screw to raise or lower the screen
frame, while in the other direction the jack screw remains stationary during handle movement. The
spring-loaded pawl permits the operator to switch the direction to either raise or lower the screen
frame, as required.
Using the AWD to elevate the discharge end of the screen frame slows the forward progress of
the slurry over the screen bed (Figure 4-4). The screen frame may be elevated several degrees,
as determined by several factors:
• Particle size
• Concentration of solids in the slurry
• Feed rate
• Type of slurry
• Type of screen
• Screen cut point
