Raymond® Mechanical Air Separators

With more than 100
years of experience,
Alstom is a leader in the
design, manufacturing
and construction of
industrial milling and
classification equipment.

Produce Materials with High Fineness
Raymond Mechanical Air Separators: Produces material with high uniform fineness,
operates in open or closed circuit and is excellent for de-dusting. It can provide drying
and cooling, and features the unique single or double whizzer for faster separation of
fines and more positive rejection of oversize.
Built in eleven sizes ranging from 4’ to 24’ in diameter, as well as a 30” unit for small
capacities and test runs. Each size is available in a single or double whizzer
configuration.

Reliable Solutions
Single whizzer air separator
Single whizzer separators have one row or bank of whizzer
blades to set up centrifugal action. This unit is ordinarily used
for coarser separations up to approximately 10-15% R74
microns (85 to 90% passing 200 mesh) which is excellent for
de-dusting and raw mix cement operations.

TPWR/PRSHT/IMRHPBM/US/5.2013/USA/1504

Double whizzer air separator
Double whizzer separators have two rows or banks of
whizzer blades. In normal operations they can produce
finished materials up to 0.5-1% R44 microns (99 to 99.5%
passing 325 mesh) and in finished cement circuits 2800 to
6000 Blaine or masonry cements.
Experience
Raymond pulverizing and classification equipment has been
setting the standards in size reduction since 1885, serving
many types of mineral processing industries. Our portfolio
includes not only the Raymond Mechanical Air Separator but
the Raymond Jet-Stream™ Classifier, Raymond Turbine
Classifier for Roller Mills and the Raymond Hybrid Turbine
Classifiers for Bowl Mills.
