Removing the Stack Assembly
The stack assembly can be removed from the test chamber by
grasping the locking arms on the column lock assembly and pulling
straight down. The stack assembly will lock and the stack can be slid
straight out of the test chamber.
Disassembling the Stack Assembly
Sliding a thumb and forefinger into the openings between the lowest
sieve or spacer and the column locking arms can disassemble the
stack assembly. While steadying the stack with one hand, spread the
column locking arms with the other hand. The spring-loaded column
lock will release. It can then be carefully removed and access gained
to the rest of the stack components.
Selecting the Sieves for Analysis
Select the sieves required for analysis. The height of the testing stack
used within the L3P is a fixed height.
U.S. Standard Sieve Series – 5/8” overall height
A maximum of six U.S. standard series sieves (sieve sizes #3.5
through #635) may be used at one time. Any combination of sieves,
accessories, or spacers making up the standard stack height of six
standard sieve units may be used.
Precision Electroformed Sieve Series – 1-1/4” overall height
A maximum of three precision electroformed sieves may be used at
one time. Any combination of sieves, accessories, or spacers making
up the standard stack height equivalent to three precision
electroformed sieves may be used. When performing separations
30µm or finer, use only one precision sieve at a time.
Accessory Usage
When sifting powders 45µm and finer, or with powders of any
distribution showing high electrostatic charges, the use of the
Advantech L3-N8 Horizontal Pulse Accessory is recommended. It
takes the place of one standard series sieve (5/8” height). The
operating principle is the introduction of a high-speed shock wave sent
across the sieving medium. The net result is a further reorientation of
particles, a shearing action on agglomerated particles, and a reduction
of screen blinding (plugged openings).
