» The Screw Compactor provided by Fairfield is used to reduce the moisture content,
organic content, and volume of screening material coming from the shaft less screw
conveyor. Screening material is entering in an inlet hopper, which will include
a mechanical divider that will direct the screening to the compactor. From the inlet
hopper screening material will be transported by the rotating screw in to the washing
zone. In the washing zone wash water is sprayed through the hollow shaft screw in
to the screening material, During normal flow condition compactor shall be operated
in forward and reverse direction.
» The Fair Field service company offers the Screw Compactor manufactured with a through
conveying section and screw. The covers are tightly bolted onto the trough and seal
» During pick load condition the washing process automatically switch to forward direction
to handle the large amount of screening with only short interval of reversing, to
ensure that the material does not accumulate on the shaft of screw. Discharge piping
is provided at the discharge end to dewater the screening.
