Particle sizes for the recorded sample and sampling time.
Sample assessment
The catalyst formulation has an explicit median range. Its substantial coarser fraction makes it necessary to distinguish median acceptance from full-distribution fineness. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Reach D50 within 2–7 µm.
Equipment and selection
The recorded planetary machine is QXQM. The corresponding TENCAN family is the Omnidirectional 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 | 500 mL alumina jar and standard zirconia balls; 300 g catalyst formulation; omnidirectional 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
After 2 hours in the QXQM planetary mill, the sampled formulation measured D50 = 3.69 µm and D90 = 17.45 µm. No initial distribution or chemical formulation is disclosed in the record.
Measured after 2 hours for the 300 g catalyst formulation in the 500 mL alumina jar.
Interpretation
The median endpoint lies within the requested 2–7 µm range. The larger D90 is compatible with a broad distribution and must not be described as an all-particle 7 µm result. Catalyst activity, composition uniformity and durability were not measured.
Practical precautions
Define contamination limits for the actual catalyst chemistry before a repeat. Retain the documented sample mass and jar/media combination, and use a separate catalytic-performance test if the powder size is intended to support a functional claim.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Vertical Planetary Ball Mill. For catalyst formulation, a matched vertical XQM trial can test whether conventional orientation preserves the catalyst median range and coarse tail independently. 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.
