Particle sizes for the recorded sample and sampling time.
Sample assessment
The GAGG crystal was reduced mechanically before milling. Its recorded powder objective concerns D90, with no inferred crystal formula or maximum-size claim. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Reach D90 below the recorded 50 µm objective.
Equipment and selection
The recorded planetary machine is XQM-0.4A. The corresponding TENCAN family is the Benchtop 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-0.4A |
|---|---|
| Documented setup | 100 mL zirconia jar and zirconia balls; 155 g pre-reduced crystal; dry milling; speed setting 650; XQM-0.4A machine. |
| 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 crystal was mechanically reduced before the planetary stage. After 2 hours of dry milling, the sampled powder measured D50 = 7.63 µm and D90 = 19.07 µm. The separate media field records large, medium and small ball fractions of 50%, 30% and 20%; no individual ball diameters are supplied.
Measured after 2 hours for the pre-reduced 155 g GAGG sample in a 100 mL zirconia jar.
Interpretation
The documented D90 was below 50 µm. The result applies to this preparation and does not establish a maximum particle size or the performance of an unrecorded crystal composition. The source uses the GAGG name without specifying a full chemical formula.
Practical precautions
Preserve the preliminary reduction step and use the exact permitted load for the selected benchtop machine. Check wear contamination against the intended use of the crystal powder, and document ball diameters in a repeat.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Omnidirectional Planetary Ball Mill. For gagg crystal, a matched QXQM trial can test whether changing orientation affects the GAGG coarse percentile after preliminary size reduction. 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-0.4A; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
