Spiral Washers
A large proportion of aggregate
used in the production of
concrete and road wearing
materials require to be washed
in order to maintain a
consistent end product free from
impurities. In both instances
the cleaner the aggregates and
sand the less cement and bitumen
is required in the mix. The
cement and bitumen represents
the majority of the mix cost
although representing only a
fraction by weight. It is
therefore of the utmost
importance to maintain a high
quality clean aggregate.
Machine Roll’s spiral washers
clean and dewater the end
product, breaking up small
amounts of soluble mud and clay
to meet required specifications.
All coarse and fine material is
thoroughly washed while unwanted
organics, fines and foreign
materials are removed. They are
used after a sand
classifying/blending tank system
or after a wet screening
operation for such applications
as concrete, mortar and plaster
sands.
