Compared to a traditional shake-out, sand
cooler and casting cooler the DISACOOL
Lower capital investment
Low operation costs
Low energy consumption
Minimum service and maintenance
Short cooling times
A highly efficient combination of mould
shake-out, sand cooling, lump crushing,
homogenization and casting cooling in
Complete integration with moulding
Enclosed process for a cleaner and qui-
DISACOOL – all-in-one separation
and cooling of sand and castings
Effective cooling of castings
The moulding sand and castings are cooled
by evaporation of residual water in the sand
and water is sprayed into the drum. A coun-
ter air flow through the drum removes the
resulting water vapour and increases the
Castings are tumbled gently with the
sand in a smooth process lasting 20-30
Sand lumps are broken and the sand is
effectively blended prior to screening off
in the drum end screening section.
The cooled castings are discharged at
the DISACOOL outlet.
As no grinding media is used for sand
separation in the DISACOOL, the sand is
free of these metal fragments and can be
directly recycled back to the sand plant.
The result of more than 30 years’ development, the DISACOOL ensures a
gentle and effective separation as well as cooling of sand and castings using
a unique water evaporation system. An all-in-one system eliminates the need
for a separate shake-out, sand cooler and casting cooler.

Casting discharge temperature
The final casting temperature is typi-
cally between 70 and 90°C with an inlet
temperature of approx. 700°C, depend-
ing on the type of casting and flow rate
through the drum.
Sand discharge temperature
A sand temperature between 45 and
55°C and a moisture content of about
1.5% (max 1.
