GRADEX® 2000 Particle Size Analyzers are patented PC-controlled devices which
fully automate the sieve analysis process. The GRADEX 2000 provides analysis and complete data printouts
automatically – in the lab or on the plant floor – making SPC a reality for today’s quality-conscious processor.
Every aspect of the GRADEX 2000 is engineered to provide the dependability and low maintenance operation
cutomers have come to expect from ROTEX.
FULLY AUTOMATES the entire sieve analysis process, GRADEX 2000 enables
the user to analyze product on a more frequent and timely basis – permitting closer control of raw material
receipts, materials in process and finished product. Further, it frees technicians to perform other work,
while at the same time it improves test accuracy and repeatability over manual methods by eliminating operator
error and bias.
How It Works
More than ten years of in-use experience has demonstrated that
GRADEX 2000 provides consistent, reliable performance with extremely low maintenance. When
maintenance is required, all components are easily accessed and serviced.
Standard Test Sieves
GRADEX 2000 uses standard 8" (or 200 mm) round test sieves, either full or half-height
size, which can be easily inserted and changed to suit specific test requirements.
Preset Test Configuration Files
Operator pours sample into machine onto the sieve stack, and initiates test with
a single keystroke.
Easy Loading of Material
Operator simply pours sample into machine onto the sieve stack, and initiates
test with a single keystroke.
Duplicates Accepted Manual Sieving Process
GRADEX 2000 shakes and tap for a preset time, using the same stroke and frequency
as typical manual shakers.
Automates Dumping, Weighing, & Brushing
Each fraction is dumped into a collection tray which rests on a digital electronic
balance. Each sieve is brushed prior to the material being weighted. Data is recorded
for all fractions and electronically transferred to the PC.
Customized Data Presentations
Operator can view data one test at a time, or create custom reports to view groups
of results, data vs. time, lot summaries, etc.
GRADEX 2000 is now being used to automate
sieve analysis and augment quality control programs in scores of applications worldwide.

Installation Options
PC-Control The GRADEX 2000 software is Windows® based and provides
the greatest operational flexibility. It can be set up in the test lab or any other environment
where a standard PC can be used.
Computer Control Cabinet The GRADEX 2000 control systems
can be housed in a free-standing console, complete with dual fans that keep your machine
dust free. The console serves as an operator work station, housing the PC keyboard, monitor
and printer.
