XSG-4 lab use rotating flash dryer with bag filter and cyclone
Screw Feeder Industrial Rotary Dryer , Rotary Drying Equipment With Bag Filter / Cyclone
Operation:
XSG-4 lab use rotating flash dryer with bag filter and cyclone uses
a heated gas to pneumatically convey the feed up a flash tube and
into a primary air separation device; most commonly a cyclone. Air
is induced or forced into the feed area through a hot gas generator
where it entrains the feed and flashes off the moisture as it
conveys. The product is fed into the throat of the feed area in a
controlled fashion. The particles attain a velocity in the order of
80% of the conveying velocity. Secondary dust collection such as
multiclones, baghouses, scrubbers and electrostatic precipitators
are required for fine products.
Feeding / discharge:
Automatic and continuous. Vibrators, screw feeders, rotary
airlocks, double flap valves, gravity chutes. Backmixing is most
effective on sludge's. Feed introduced into airstream via venturi
or use of disintegrator technology.
Feed Characteristics:
Slurries, pastes, and sludges (all with back mixing), friable
filter cakes, powders, granules. Feed needs relatively consistent
particle size. Very large particles present challenges. Low to high
feed rates
Heat Source:
Steam, electrical, coal, liquid fuels, or gas
Exposure:
Mostly Direct. Flow is co-current.
Residence time:
Extremely short (seconds). Residence time can be altered by
increasing hold up times in cyclone.
Extraction:
Normally induced. Systems can have combustion, forced and induced
draft fans for operation.
Dust Collection:
Cyclones, baghouses, scrubbers, Electrostatic precipitators.
Systems require significant dust collection since this is the
product collection mechanism.
Control:
PLC, infrequently solid state controllers. System controls on
discharge temperature. Can modulate energy and feed.
Benefits:
Very intimate contact with air/gas stream
Excellent transfer of energy
Ideal for heat sensitive, explosive or reactive products
Small real estate requirements
Flash tube is flexible, can be routed within plant constraints
Low maintenance - few moving parts
High temperature operation
Limitations:
Loss of power will cause product to fall into dryer base
May cause size reduction due to attrition and impact
High energy costs for fans and dust collection
Products displaying a high degree of bound moisture may not be
suitable for this technology
May be susceptible to high wear if improperly accounted for
