Page 5: Description
Solids produced can be composted for sale or, in the case of dairies, reused as bedding material for cows. Valmetal designed the heavy duty 12” x 8’ inclined screw press to have the same functionally as the traditional screw press but produce a finished product that is significantly drier with more control of the dryness of the dewatered solids.

Page 7: Installing Hopper Diaphragm Switch
NSTALLING HOPPER DIAPHRAGM SWITCH The diaphragm switch on the screw press is usually interlocked to the separator control panel. If the screw press hopper is too full, it will shut off the feed pump to the separator system temporarily. This allows the screw press to clear out prior to resuming normal operation, preventing the hopper from overflowing.
