• Fast, efficient separation of dry, flowable materials.
• Exclusive AutoSift self-adjusting controls.
• No.18-No.635 sieve range (1,000µm-20µm size range).
The GilSonic SiftMaster applies the proven efficiency
of sonic separation to rapid continuous
production sizing of flowable powders. Both power
level (amplitude) and pulse frequency of the unit
are quickly “tuned” for individual material types.
Gilson’s AutoSift electronic control monitors and
adjusts material flow for maximum output with clean
separation. Dual-position tap de-blinding keeps
meshes clean. Once feed and product collection
are set, no further operator attention is required.
The device is ideal for low-volume continuous
production of many materials including powdered
metals, ceramics, minerals, ores, chemicals, cements,
etc. Sealed all-stainless contact areas
are easily accessible for food or pharmaceutical
cleanups or for other low contamination applications.
The unit is also suited to research or pilot
Normal sifting devices use movement of the screen
surface to throw material and rely on the limited
force of gravity to return particles against sieve
meshes. Difficult fine or low density powders do
not separate efficiently. By contrast, SiftMaster
has a stationary sieve surface. Particles are lifted
and forcibly tried to meshes by an oscillating air
column that may be tuned to 2,400—3,600 tries
per minute. Downward thrust by the air column
acts as a “gravity-assist” to permit sifting many particles that will not separate by conventional
means. For easier materials, the “assist” yields
increased throughput and efficiency. Gentle sonic
action assures screen wear and particle degradation
Setup conditions for a given material are all
established in minutes by simple manual adjustments
while observing sifting action through the
When switched to AutoSift mode, an electronic
sensor monitors material passing wire cloth
mesh. When incomplete separation is sensed,
AutoSift cuts power output. When clean separation
is restored, power is automatically increased
again. Highest throughput with sharp separation is assured. Sensors are continuously cleaned by
a built-in air supply stream. Wire Cloth Units are
changed through a front opening in less than a
minute. SiftMasters may also be stacked or operated
The SiftMaster is supplied on casters with 6ft (2m)
of flexible hose that may be cut as desired to fit
feed inlet and oversize/undersize outlet ports with
clamps provided. For additional hose and clamps,
order GAA-14 Kit. A freestanding, stainless steel
1.5ft³ (45qt) Feed Hopper is available as GAA-12.
Round stainless steel containers for storing or collecting
powders all have two welded-loop handles
and matching cover. MA-90, MA-91, & MA-92 fit
below oversize or undersize outlets; MA-93 &
MA-94 fit oversize outlet only.
