Rheo3000 Software
for Quick and Comprehensive Data Analysis Capabilities with RST series Rheometers
Enhance your
productivity
VIA PC CONTROL WHEN
CHARACTERIZING
MATERIAL RHEOLOGY
Viscosity Flow Curve: controlled shear stress
ramp produces viscosity vs. shear rate graph
for two pseudoplastic materials.
Yield Stress Determination: shear stress ramp
from 0 to 800 Pa over 2 minutes shows yield
stress values of 200 and 400 Pa for two
materials.
Thixotropy Analysis: Up/down shear rate
ramp produces two shear stress vs. shear rate
curves; thixotropy calculation is 20977 Pa/s
(the area between the curves).
Temperature Profile: Viscosity is measured
at constant shear rate of 250 1/s while
temperature increases from 25°C to 90°C
using RST Cone Plate Rheometer.
Your PC can do the detailed data
collection and analysis work for
you. Rheo3000 allows you to
program the RST Rheometer and
control shear stress or shear rate.
Data is saved in a SQL database
for easy access by multiple
users on a network. Use multiple
step test programs for complete
characterization of material flow
behavior: viscoelastic modulus,

What is powder analysis?
What are the industrial issues with
powders?
The classic problem with powders is their failure to
discharge reliably from bins, hoppers, silos, etc., and poor
or unpredictable flow in feeders, dosing machines, packing
machines, etc. This causes unwanted interruptions in the
production process, leading at times to complete plant
shutdown in order to correct the flow restrictions and
stoppages. It also leads to variations in pack weight, mixture,
performance and sensory properties of powder products.
Particulate materials constitute
a large group of solids that can range in size from
submicron particles to large rocks and minerals. Brookfield’s
Powder Flow Tester measures the flow behavior of bulk solid
materials that have a top particle size of 2mm. At least 90%
of the sample should consist of particles less than 1mm in
diameter. In many instances, powders with larger particles can
still be characterized effectively by sieving the material at 1mm
and testing the fines (the fines control the flow properties of
a material with a wide size range). The generic term used by
Brookfield to name these materials is “powder”, therefore the
name of our instrument is “Powder Flow Tester”.
Unlike liquids which, under the influence of gravity, tend to
have a horizontal surface, powders exhibit a structure, due to
internal friction and cohesion, which allows them to form piles
with angles relative to the surface on which they are placed.
At ambient conditions, powders do not change flow behavior
when subjected to variable shear rates, whereas most liquids
do. However, pressure controls the strength of a powder (i.e.,
increases the resistance to flow) whereas a liquid will show
limited change in rheology under pressure. In other words, the
consequence of subjecting a powder to a compressive force is
that the powder will flow less easily; the relationship between
the compressive stress applied to consolidate the powder
and the strength it obtains is the measurement of the powder
flowability, or its “Flow Function”.
Quality Control Departments are constantly dealing with raw
materials in powder form, which come from multiple suppliers.
The variability in particle size and distribution, moisture
content, and basic ingredients requires a battery of incoming
inspection tests, none of which assure that proper flow
will take place when loaded into the plant equipment. The
Brookfield Powder Flow Tester is a single-solution instrument
which can resolve this uncertainty.
R&D Departments are constantly adjusting formulations of
powder products to satisfy customer demand for improved
properties: better coating action for paints, enhanced taste for
spices, rapid dissolving of chemicals when put into solution.
New formulations do not necessarily have the same flow
properties, thereby leading to production problems when the
process is scaled up to high volume. The Brookfield Powder
Flow Tester can predict those problems so they can
be prevented.
How can flow problems
with powders be eliminated?
There is a proven scientific method, called the “Flow Function
test”, which can analyze powders for flow behavior. ASTM
D6128 describes this procedure for compressing and shearing
powder samples in a defined annular shear cell, using a welldefined methodology established years ago.
There is a need throughout industry to characterize powder
flow properties and flow behavior. The Brookfield Model PFT
Powder Flow Tester is a precision instrument of robust design
that satisfies this need and more.
B ROOKFIELD PFT P OWDER F LOW T ESTER
Test algorithm for powder
flow analysis requires
compression of the
sample contained in an
annular cell to a defined
axial load followed by
torsional shearing. Raw
data output shows
torsional load values in
red. Compression of the
sample is shown as axial
load values in green.
The resulting data produces a “Flow Function”, much like what is
obtained for liquids when testing with a viscometer to create a
“flow curve”.
Flow Function for
powder sample shows
“non-flowing” to “very
cohesive” behavior at low
consolidation stresses
and “cohesive” behavior
at higher consolidation
stresses.
Analysis of the “Flow Function” leads to calculation of the
critical outlet dimensions of feeders, hoppers, etc., through
which the powder will flow. Comparing the “Flow Function”, or
these critical dimensions, allows powders to be benchmarked,
ranked and compared against one another for flowability. The
dimensions can also be used to determine whether a particular
powder will flow through an existing plant or process, or to
determine what the geometry should be if purchasing new
solids handling equipment.

Data output from Flow Function test provides “Arching Dimension”
and “Rathole” diameter. Data output from additional Wall Friction test
provides “Hopper Half Angle”.
Although ASTM D6128 has existed for many years, the
instrumentation used to accomplish the test has been
expensive to purchase, requires an experienced operator, and
may need a technical expert to interpret the results.
