Particle sizes for the recorded sample and sampling time.
Sample assessment
The diamond slurry has one measured endpoint after four hours. Requested earlier sampling times cannot supply missing kinetic data. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Collect samples over a treatment extending to 4 hours; no numerical size limit is stated.
Equipment and selection
The recorded planetary machine is QXQM. The corresponding TENCAN family is the Laboratory Full-Directional 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 | QXQM |
|---|---|
| Documented setup | 250 mL zirconia jar with standard zirconia balls; 49 g diamond powder plus 31 g alcohol; wet milling; 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
The requested sampling times were 0.5, 1, 2, 3 and 4 hours. The procedure supplies a numerical result only at 4 hours: D50 = 2.72 µm and D90 = 16.63 µm. It does not provide measurements or confirmation of sampling for the earlier requested times.
Measured after 4 hours for the 49 g diamond powder with 31 g alcohol.
Interpretation
The supported result is the measured 4-hour powder distribution. A full kinetic curve cannot be reconstructed from a sampling request alone. No size acceptance threshold or surface-morphology requirement is recorded.
Practical precautions
Document actual sample withdrawals and their masses in a repeat study. Confirm alcohol-compatible containment and inspect zirconia wear; abrasive diamond can make contamination assessment important for subsequent powder analysis.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Vertical square planetary ball mill. For diamond powder, a matched vertical XQM trial can test whether conventional orientation preserves the diamond coarse tail using the same withdrawal schedule. Retain the same sample and media. 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 QXQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
