 HEAVY-DUTY
SCREW CLASSIFIERS
GreyStone provides a complete line of heavy-duty Screw Classifiers that
can be specified with either a single or twin model screw classifier.
MULTIPLE
SCREEN OPTIONS
The Aggre-Washer accommodates several types of horizontal screens. A
producer can use his own screen or GreyStone will provide a screen.
Semi-portables can be equipped with either an incline or horizontal
screen.
 LARGE
FEED HOPPER
A large feed hopper with a water system ensures maximum production to
the screen. The feed hopper also allows for material to be converted
to slurry prior to entering the screen decks.
CROSS
CONVEYORS
Cross conveyors can be either 24" or 30" wide and are 12' long. The
reversible cross conveyor allows for distribution of material on both
sides of the wash plants.
SCREEN
DISCHARGE CHUTES
Screen discharge chutes have A-R plate steel chute liners for maintenance-free
service life. The chute design allows operators to discharge each product
directly onto radial stacking conveyors.
SPRAY BARS
Each deck is equipped with spray bars to ensure maximum washing. Valves
allow the operator to regulate GPM and tailor the washing action of
the material.
WORK
PLATFORM
A large work platform with safety railings and toe boards gives the
operator a safe area to change screen cloth, adjust spray bars, and
monitor screen operation.
