Sample assessment
The metal powder is not chemically identified in the source. Two measured long-duration endpoints are documented without inferring alloy composition. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Process for 24 hours and record the resulting distribution.
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 | 500 mL stainless-steel vacuum jar; 160 g of supplied balls with composition unspecified; first powder charge 158 g; full-directional dry milling; speed setting 94. |
| Recorded operating cycle | Run 30 / pause 10; 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 first preparation measured D50 = 7.27 µm and D90 = 12.99 µm after 24 hours. A second preparation also sampled at 24 hours measured D50 = 8.64 µm and D90 = 15.29 µm. No evacuation, gas-filling step or complete second charge is given.
Interpretation
The two measurements document observed powder distributions at the requested duration. They do not establish alloy identity, equivalent loading in both jars, a reduction ratio or a preferred milling mode. A vacuum-jar label does not itself establish the atmosphere used.
Practical precautions
Identify the powder and supplied media before transferring the method. Confirm the full loaded mass and actual atmosphere, and retain separate sample records rather than averaging the two endpoints into an unrecorded result.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Vertical square planetary ball mill. For unspecified metal powder, a matched vertical XQM trial can test whether conventional orientation preserves the two metal-powder endpoints after identity and loading are confirmed. 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.
