Introduction
Physical measurements, such as particle size,
surface area, density, etc. and chemical analy
-
sis of crushed ores for example often require
reduction of large quantities into smaller
samples. Therefore it is necessary that the
powder sub-sample used for analysis be
representative of the initial lot or batch for
reproducible and valid data.
Both of Quantachrome's rifflers are designed
to accurately and reproducibly prepare such
representative powder samples from larger
laboratory or bulk quantities using the statisti-
cally superior method of spin, or rotary, riffling.
The Rotary Micro Riffler easily and automatically divides samples
into eight(8) smaller representative samples for analysis. By repetitive
divisions of the collected smaller samples, the desired final sample
size can be easily obtained.
The Rotary Micro Riffler has two basic components: a circular
vibrating bowl and a sample collector. The vibrating bowl is ampli-
tude variable and controls the delivery rate of the initial powder
sample. The collector consists of a rotating splitter holding eight
test tubes. The size of the test tube may be varied to accommodate
the initial sample size. Test tubes afford simple filling, emptying
and cleaning.
To accommodate materials of different flow ability the Rotary Micro
Riffler has two sets of controls: one for the delivery rate and the
second for the rotation rate of the collectors. By varying these
two controls, accurate divisions of any powder may be achieved,
regardless of particle size or density, in a reasonable time.
To divide a sample, up to 120 cm
3 of powder is loaded into the
vibrator bowl. The vibrator bowl automatically feeds the collector
and the test tubes rotating below the feed chute. After all the
material has been delivered into the test tubes, further reduction
in sample size may be accomplished by emptying the contents of
one or more of the test tubes into the bowl and repeating the proce -
dure until the desired sample size is achieved.
