Sample assessment
Two activated-carbon charges have independent time series. The size objective does not establish adsorption performance, and the mass-field conflict requires clarification. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Reach the recorded D50 objective of 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 | 1.5 L alumina jar with standard zirconia balls; separate sample charges 100 g and 88 g; dry milling; speed setting 450. |
| 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
The 100 g sample measured D50 = 7.5 µm and D90 = 14.03 µm at 15 minutes, then 3.65/5.84 µm at 1 hour. The 88 g sample measured 6.7/12.76 µm at 15 minutes, 3.89/6.61 µm at 45 minutes and 3.4/5.45 µm at 1 hour. A separate mass field says 1100 g; the individual procedure charges are retained here because they identify the measured samples.
Interpretation
Both samples were already below the D50 objective at the first measured time and became finer at later reported times. This does not establish adsorption performance or a maximum particle size.
Practical precautions
Resolve the conflicting aggregate mass field before repeating. Keep the sample charges and time series distinct, and assess adsorption properties, wear and powder recovery independently of the size measurement.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For activated carbon, a matched QXQM trial can test whether changing orientation affects each carbon charge at its earliest conforming median. 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.
