new portable dewatering screen solution for the North American aggregates
industry.

 

The Portable Aggre-Dry Dewatering Screen from GreyStone,
Inc. features a patented flume, allowing an operation to retain all of the
fines discharged from the dewatering screw. The addition of the flume offers a
flexible and cost-efficient solution for controlling, recycling and saving
water and fines while producing sand and gravel products with a moisture
content as low as 7 to 12 percent, along with a caked, dry sand product that an
inclined dewatering screw alone cannot not achieve. Wheel-mounted for easy
transportation, this 5-ft x 10-ft dewatering screen is ready to connect to a
washing screw for on-demand production.

The Portable Aggre-Dry has several unique features,
including a 0.25-mm screen opening, which reduces the amount of material that
can fall through the screen. The feed from the screw allows the material to
build to a bed depth of up to 14 inches on the screen, squeezing additional
moisture from the sand as the vibratory motors move it along the length of the
screen deck, further reducing moisture content. There are screen panels on the
sides of the Portable Aggre-Dry, which allow for even more water to be removed
from the material.

 

GreyStone prides itself on providing the industry with the
most complete line of sand washing, classifying and dewatering equipment for
keeping material in spec. Whenever possible, GreyStone builds its equipment
with components that can be replaced locally, so when maintenance and service
are necessary, producers are up and running quickly.
