1. Define the Boundary
Provide the material name, SDS, basic chemistry, moisture condition, hardness or abrasiveness, and any known reaction risk.
Sample Testing
What to Prepare Before Sending Powder for Testing
A checklist for material identity, safety data, feed size, target PSD, capacity, test method, sample quantity, and special handling conditions.
Practical Review Framework
Use the following checks together with the delivered equipment manual, the material safety information, and project-specific operating procedures.
2. Check the Process
Define the target with D50/D90/D97 or residue, plus the measurement method and application acceptance criteria.
3. Confirm with Evidence
Confirm the sample quantity, packaging, return or disposal method, confidentiality needs, and required atmosphere before shipment.
What to Record
Record the material batch, feed condition, equipment configuration, operating parameters, sampling method, particle-size method, output, temperature, pressure trend, and any abnormal observation. Comparable records are more useful than isolated numbers.
Need a Project-Specific Answer?
Send the material name, target PSD, capacity, current process problem, and available test data. We can help identify the next information needed for selection or troubleshooting.
