Sample assessment
The two silica-sand portions have direct all-passing sieve observations. The earlier percentile measurement and later sieve results answer different questions. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Obtain complete passage through a 200 mesh sieve.
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 agate jar and standard agate balls; first silica-sand portion 146 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
For the first portion, the 2-hour sample measured D50 = 39.74 µm and D90 = 86.97 µm. At 3 hours, all material passed the 200 mesh sieve. A second sand portion processed by the same recorded method also passed completely through the 200 mesh sieve after 3 hours.
Interpretation
The complete sieve-passage observations supply direct evidence for the stated preparation target in both portions. The 2-hour percentile pair is an earlier analytical result and is not a substitute for the later sieve test. No mesh-to-micron conversion is made.
Practical precautions
Confirm the sieve standard, aperture, dry-sieving method and recovery mass when repeating. Keep the two sand portions separately labelled and assess agate wear or cross-contamination if the material will be used for elemental analysis.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Omnidirectional Planetary Ball Mill. For silica sand, a matched QXQM trial can test whether changing orientation affects complete silica-sand sieve passage at a matched preparation time. 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.
