Particle sizes for the recorded sample and sampling time.
Sample assessment
The carbon powder has a narrow specified median range. A recorded speed increase precedes the successful sample and belongs in the procedure. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Reach D50 between 8 and 10 µm.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical square planetary ball mill. The jar volume identifies the test container and does not establish an exact machine variant or production capacity. Equipment association follows the recorded machine designation.
Test setup
| Recorded planetary machine | XQM |
|---|---|
| Documented setup | 250 mL alumina jar and standard zirconia balls; 30 g fine carbon powder; dry milling; initial speed setting 480. |
| Recorded operating cycle | Run 5 / pause 1; units not stated in mode field |
Speed values are reproduced as recorded settings. A rotational unit and planetary-disc versus jar-speed basis are not stated, so these numbers are not labelled rpm.
Recorded procedure and results
After the first 30 minutes the speed setting was increased to 550. The 3-hour sample measured D50 = 8.07 µm and D90 = 15.23 µm. The separate test record duration field is 8 hours and is not associated with an additional reported size measurement.
Measured at 3 hours after the recorded speed increase; this is not an 8-hour measurement.
Interpretation
The documented 3-hour median met the stated range. The result cannot be assigned to an 8-hour endpoint or to an unchanged speed setting. D90 supplies context about the coarser fraction and is not the acceptance criterion in this record.
Practical precautions
Retain the recorded speed change when repeating the run. Clarify the separate duration entry if scheduling is required, and measure recovered mass and adhesion because neither is quantified in the source.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For carbon powder, a matched QXQM trial can test whether changing orientation affects the carbon median range with the same staged speed settings. Keep sample mass, media and sampling times controlled. This is a proposed comparison; the test record does not demonstrate a superior result for that alternative. Confirm jar compatibility and the permitted complete loaded mass before selecting a configuration.
Procedure records XQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
