Sample Testing Before Equipment Selection

Evaluate how your powder responds to milling or classification. A representative material trial helps define the particle-size target, process conditions, and equipment configuration.

From Sample to Selection

Review the MaterialShare the material, intended use, feed condition, and known safety requirements.
Agree on the TrialConfirm the target, sample quantity, measurement method, and shipping arrangements before sending material.
Test and MeasureRun the agreed milling or classification trial, then check the sample's particle-size distribution and processing behavior.
Review the RouteUse the test data to discuss a suitable model, system configuration, and further scale-up checks.

Inside the Test Center

Separate testing rooms and sample-handling areas support material trials before equipment selection.

Measurement and Sample Evaluation

Particle-size analysis, weighing, and morphology observation help connect trial results with your product requirements. The test methods and reporting scope are agreed for each material.

Useful Information Before a Trial

You do not need every answer to start a discussion. Existing reports and material information help us identify what the trial needs to verify.

Read the sample-testing checklist
MaterialName, intended use, hardness, moisture, and heat or oxidation sensitivity.
Particle sizeCurrent feed size and the required product size or sieve-residue limit, if known.
CapacityExpected output, batch size, and batch or continuous operation.
SafetySDS / MSDS, known hazards, and any requirement for an inert atmosphere.
PurityContamination limits, contact-material requirements, and cleaning needs.

Sample Testing Questions

What if I do not know the target particle size?

Start with the material and its intended use, or describe the problem with your current powder. We can discuss which particle-size measurements are useful before defining the trial.

How much sample should I send?

Sample quantity depends on the material, equipment, and number of trial conditions. Contact us first so that we can agree on the amount, packaging, and shipping arrangements.

Can you evaluate oxidation-sensitive or heat-sensitive powders?

Tell us about temperature limits, moisture sensitivity, and any known hazards. Share an SDS / MSDS where available. The material review determines whether a suitable test configuration and protective atmosphere can be arranged.

What will the trial help me decide?

The review brings together the measured particle-size distribution, observations during processing, and the equipment configuration used. Agree in advance on any additional measurements needed to judge your process.

Will a trial guarantee the same production output?

Production capacity depends on feed properties, product specification, utilities, and system scale. Trial data supports equipment selection; the production target and acceptance conditions must be agreed for your project.

Request a Sample Trial

Describe your material and testing objective, then leave an email address or phone number. Unknown technical parameters can be left blank.

Add Sample and Particle-Size Details (Optional)

Enter only the particle-size values you know, with units. A full D0–D100 data set is not needed to request a trial.

Please contact us before shipping samples. Supporting reports and an SDS / MSDS can be sent by follow-up email. See our Privacy Policy.
