Sample assessment
The trial concerned a pigment powder with no composition or initial distribution supplied. A PTFE jar and zirconia media were recorded.
Analyst consideration: For pigment powder, wall and ball deposits can change the recovered composition and apparent fineness. The nonadhering accepted sample is useful, while pigment functionality remains a separate question.
Recorded objective
Observe milling behavior and obtain an acceptable sample; no numerical fineness target was entered.
Equipment and selection
The machine entry is XQM. TENCAN Vertical 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 | PTFE500 |
|---|---|
| Media entry | Zirconia 500 |
| Media-charge notation | 3-200/5-100/8-50/1050/12-50/15-50/ |
| Sample-load entry | 60 (unit not stated) |
| Controller speed setting | 500 |
| 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
At three hours the procedure explicitly records no adhesion and states that the sample met the requirement. The setup contains a mixed-media notation, including an unresolved 1050 entry. No D50, D90, sieve result or sample-temperature reading was supplied.
Interpretation
The recorded success combines acceptance with a nonadhering material observation. It remains a qualitative result and does not support a final size claim. The media shorthand should be resolved rather than silently expanded into assumed ball diameters and masses.
Practical precautions
Confirm the ambiguous charge entry before repeating. Use a feed sample and define a measurable endpoint if the next trial is intended to substantiate a particular fineness.
TENCAN alternatives to evaluate
TENCAN Omnidirectional Planetary Ball Mill. For this pigment, a QXQM comparison can examine whether changing orientation affects wall and media adhesion. Retain the three-hour check and resolve the 1050 charge entry first. Changing bed orientation through QXQM tumbling gives a specific comparison of pigment contact and redistribution, with deposits and recovery measured under the same charge. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM source entry; only recorded tested series/configurations are related. No jar-volume inference.
