SDAM - Shakeout
Deck Attrition Mill
This unit not only
acts as a shakeout deck, but also includes an
integral attrition mill section. The output of this
unit is grain size and ready for cooling and
classification.
The greatest
advantage of this unit over others is the lack of a
pit requirement. The low level deck offers ease of
loading with a forklift, roller conveyor, or
vibratory feed conveyor. No pit means less cleanup
and failed springs from being buried.
Example: Dualtech
Installation. Molds are broken
up and the product removed. Sand is recovered
and recycled. |
The
basic unit will provide shakeout of the casting,
remove any larger than grain size material, and
perform the Mechanical Sand Reclamation of the sand. The
heavy-duty upper grid breaks up the mold to allow
for removal of the casting and serves to break down
the lumps into particles small enough to drop
through the top grid. Once the lumps pass through
the grid, the sand is vibrated over a perforated
plate and then a self cleaning wedge wire screen. A
final easy-access screen is mounted at the discharge
end of the unit to remove any larger than grain size
material, ceramics, metal, and slag.
|
Mechanical Sand Reclamation comes from the sand
grains abrading
against each other. This action
not only serves to
de-husk the grain, but also to
remove sharp edges
(especially from sub-angular
and angular grains)
helping reduce the required
resin addition when the
sand is reused. The
amount of resin removed varies
due to binder type,
percentage of binder in the
sand, type of metal
poured, and the sand to metal
ratio. |

Nominal throughput is
listed below and depends on resin content, resin
type, amount of burned sand, temperature of the
sand, average size of lumps or molds, and amount of
uncured resin in the sand.By
not slinging and fracturing sand grains to remove
the resin husk, this unit aides in an overall
reduction of sand fracturing, reducing overall sand
losses due to reclamation processing. This unit
coupled with a high efficiency classifier or cooler
/ classifier will allow the end user to fine tune
their reclaim sand for maximum reuse with minimum
sand losses.
