The turbine grader, as a forced centrifugal grader with secondary
rotator is composed of grading rotator, guide vane rectifier, and
screw feeder. The materials are fed through the upper cartridge,
and the grains will be sieved and well distributed by the incoming
air, which brings the grain to the grading zone. The centrifugal
force produced by the fast rotation of grading rotator together it
the centripetal force by the pneumatic adhesion act on the grading
grains. When the centrifugal force on the grain is greater than the
centripetal force, the coarser grains above the grading range will
be swirled down along the container wall. The secondary air will be
rectified to uniform cyclone through the guide vane, and separate
the thinner grains from the coarser ones. The separated coarser
grains will be blown out from the discharge port. The thinner gains
below the collector, whereas the purified air will be vented
outside from the draft.
1, Compatible with a variety of dry-type powder mill machinery (jet
mill, ball mill, Raymond mill) go form a closed circuit.
2, Wide Grading Range : d 97 =4~15um; only adjust the rotator speed
to classify grains of varied diameters and perform steeples
grading. The imported converter will auto matically control the
whole grading process.
3, High Grading Efficiency: Before discharge the impact of cyclone
on the materials separates the coarser grains from the thinner
ones, thus raising the grading efficiency and precision. Yielding
97% superfine products of less than 5 um.
4, The horizontal grading rotator, made of abrasion resistant
materials, is featured by stable operation and sustainable service
5, The grading capacity is within the range of 50 and 6000
kilograms, reducing energy loss about 40% less than the equivalent
It is widely applied to thinner grading for such nonmetallic ores
as calcium carbonate (calcite), kaolin stone, French chalk,
graphite, barite, limestone, smelt and grading for grading for
pesticide and other chemical materials.
