solution also includes a new silo for feeding stored powder
materials into the plant's packaging system and a
large wet scrubber for de-dusting. At this plant, 25 ton/h
of lignosulfonates is directly fed into a rotary atomizer and
spray dried. The final product is separated in two groups
of consecutive cyclones. The second newly developed
cyclones CEE (Cyclone Extra Efficiency) offer a higher
separation efficiency, which increases the yield and reduces
emissions. In real-world tests, the CEE powder
separation efficiency was verified as being considerably
higher than the efficiency of standard cyclones. Part of
the spray drying plant is the large wet scrubber for dedusting.
The Venturi scrubber uses water to clean the
exhaust gases from the spray dryer before they are released
into the environment. The scrubbing water is circulated
and fed continuously to a falling-film evaporator
for concentration and recovery of valuable substances.
The condensate is returned to the spray dryer as process
water, and thus increases the total product yield while the
concentrate is discharged. The evaporator is designed
for 2 h/ton of scrubbing water and energetically optimized
by heating through mechanical vapor recompression.

The high-speed Universal
Cutting Mill Pulverisette
19 comminutes up to 60
L/h of soft to mediumhard
sample
materials
and fibrous materials at
a torque of up to 30 Nm
with reliable, reproducible
results. The variable rotational
speed adjustment,
in increments of 100 between
300 and 3,000
rpm, enables fine tuning
of the comminution
process for each sample
within a very wide range
of applications. A lowspeed
version has a variable rotational speed adjustment
between 50 and 700 rpm and a torque of up to 67
Nm. The combination of low cutting rate and extreme
cutting forces enables a very powerful comminution of
hard, tough-elastic samples and small sample quantities.
At the same time, it is suitable for all cases where
thermal damage, the loss of highly volatile substances,
or an excessively high fine share need to be avoided,
says the company. The cutting mills can be combined
with a cyclone separator (photo) for sample recovery,
and an optional exhaust system. The cyclone separator
is completely made of stainless steel 304. Hall 2, Stand
