Sample assessment
Alumina and magnesium oxide were pre-crushed and processed separately. Their distinct complete-passage times should not be averaged into one oxide recipe. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Produce powder passing a 100 mesh sieve for each material.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical 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 zirconia jar with standard zirconia balls; pre-crushed alumina 79 g or pre-crushed magnesium oxide 87.5 g; dry 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 alumina was crushed before milling and passed completely through a 100 mesh sieve after 30 minutes. Magnesium oxide received the same recorded crushing and jar/media preparation and passed completely through a 100 mesh sieve after 1 hour.
Interpretation
Both materials have an explicit sieve-passage result, with different treatment times retained. The record supports the stated 100 mesh preparation objective. It does not supply a sieve standard, an aperture conversion or particle-size percentiles, and it does not prove equal milling behaviour for the two oxides.
Practical precautions
Clean and inspect the setup between materials to control carryover. Retain the pre-crushing step and identify the actual sieve specification in any repeat procedure; do not substitute an assumed micron opening for the documented mesh result.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Omnidirectional Planetary Ball Mill. For alumina and magnesium oxide, a matched QXQM trial can test whether changing orientation affects the individual alumina and magnesium-oxide sieve times. 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.
