Sample assessment
The coating formulation and its initial agglomerate state were not supplied. The recorded objective was dispersion and uniformity rather than a numerical size limit.
Analyst consideration: For a coating dispersion, breaking agglomerates and obtaining a visually even sample are not the same as long-term stability. Formulation compatibility and rheology should therefore be part of selecting the repeat method.
Recorded objective
Break up agglomerates and obtain an even dispersion.
Equipment and selection
The machine entry is XQM-2. TENCAN Vertical square planetary ball mill is associated at the recorded series level. No exact housing variant is inferred from jar capacity or an abbreviated machine label.
Test setup
| Jar entry | Steel 500 |
|---|---|
| Media entry | Zirconia 450 |
| Media-charge notation | 5-200/15-200/12-80 |
| Sample-load entry | 260 (unit not stated) |
| Controller speed setting | 550 |
| Cycle notation | 5/1 |
Unlabelled jar, media and load numbers remain source notation, not assigned units. Controller settings are not certified rpm. The cycle notation has no independently stated timing unit or reversing definition.
Recorded procedure and results
The setup lists a steel jar, zirconia media and controller setting 550. The procedure states that twenty minutes was sufficient, and the result is explicitly marked accepted. No viscosity, distribution, color-uniformity or storage-stability measurement was recorded.
Interpretation
The positive endpoint is reported dispersion acceptance after a short trial. It does not establish long-term suspension stability or an independently measured homogeneity level. The compact media charge is retained without treating it as a certified optimized recipe.
Practical precautions
Define the dispersion acceptance check for the actual coating. Record solids content, recovery and any relevant viscosity or settling observation before repeating the twenty-minute test.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. For the coating, assembly tumbling can be evaluated for dispersion and material redistribution. Compare at twenty minutes using the same formulation and an explicit uniformity check. QXQM tumbling changes redistribution of the formulation and media; a matched twenty-minute comparison can examine dispersion uniformity without assuming a new machine changes chemical compatibility. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM-2 source entry; only recorded tested series/configurations are related. No jar-volume inference.
