Particle sizes for the recorded sample and sampling time.
Sample assessment
The perlite charge was only 7.8 g. Selection must therefore preserve the small-sample loading rather than extrapolate directly from nominal jar volume. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Reach the recorded D50 objective of 8 µm.
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 and standard zirconia balls; 7.8 g perlite powder; dry milling; speed setting 450. |
| 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 perlite was dry-milled in an XQM planetary mill for 30 minutes. The endpoint sample measured D50 = 3.64 µm and D90 = 7.88 µm. The record supplies no numerical feed distribution or temperature measurement.
Measured after 30 minutes for 7.8 g perlite in a 250 mL zirconia jar.
Interpretation
The measured median was below the 8 µm objective. D90 provides additional distribution context but is a different percentile and must not replace the D50 acceptance criterion. No reduction ratio can be calculated without a measured feed distribution.
Practical precautions
Retain the very small sample loading when designing a repeat. Weigh the recovered powder and examine adhesion and dust loss rather than assuming the endpoint distribution represents complete mass recovery.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Omnidirectional Planetary Ball Mill. For perlite, a matched QXQM trial can test whether changing orientation affects the perlite median and powder recovery at this small loading. 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.
