Gradex 2000 enables the user to analyse product on a more frequent and timely basis, permitting the closer control of raw material receipts, materials in process, and finished product as well as freeing technicians to perform other work. This elimination of operator error and bias improves test accuracy and repeatability over manual methods.

More than ten years of in-use experience has demonstrated that Gradex 2000 provides consistent, reliable performance particle size analysis with extremely low maintenance. When maintenance is required, all components are easily accessed and serviced.

How Particle Size Analyser Works 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 particle size analyser uses standard 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 particle size test with a single key stroke.

Duplicates Accepted Manual Sieving Process The Gradex 2000 shakes and taps for a preset time, using the same stroke and frequency as typical manual shakers.

Automates Dumping, Weighing and 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 weighed. Data is recorded for all fractions and electronically transferred to the PC-controls for easy reporting of material sizing.

Installation of Particle Size Analyser Installation


C-Control Gradex 2000 software is Windows-based, providing the greatest operational flexibility. This software can be set up in the test lab or any other environment where a standard PC can be used.

Computer Control Cabinet Gradex 2000 control systems can be housed in a free-standing console that includes dual fans to keep the machine dust-free. The console serves as an operator workstation with the ability to house the PC monitor, keyboard, and printer.

Particle Size Analyser Specifications Specifications


Reduce Costs Frees technicians to perform other work. Increases testing capacity without additional manpower. Enables testing to move to point of sample, so line operators can conduct the testing. The ability to test more frequently decreases quantity of off-spec prod

Eliminate Errors Eliminates manual steps where errors often occur. Improves repeatability by avoiding sieve damage due to over brushing, because Gradex 2000 brushes the sieves evenly and consistently. Electronic data transfer eliminates transposition and calculation errors.

Operating Benefits Mettler Balance with capacity of 5100 grams. Accepts any manufacturer’s sieves. Enhanced Gradex 2000 software with customised reports and flexible reporting
