Sample assessment
The sample was tea leaves without a moisture or starting-size specification. An agate jar and paired zirconia/agate media entries were supplied.
Analyst consideration: For tea, moisture preparation and media contact can affect the texture and recovery of the powder. The paired media notation must be resolved before interpreting the mesh result as a reproducible preparation.
Recorded objective
Meet the recorded 200-mesh requirement.
Equipment and selection
The machine entry is XQM-1. TENCAN Vertical Planetary Ball Mill is associated at the recorded series level. No exact housing variant is inferred from jar capacity or an abbreviated machine label.
Test setup
| Jar entry | Agate250 |
|---|---|
| Media entry | Zirconia /Agate250/170 |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 30 (unit not stated) |
| Controller speed setting | 500 |
| Cycle notation | 5/1 |
Unlabelled jar, media and load numbers remain source notation, not assigned units. Controller settings are not certified rpm. The cycle notation has no independently stated timing unit or reversing definition.
Recorded procedure and results
The setup gives a controller setting of 500 and media entries 250/170. At two hours the material was sampled and packed. The result column records 200 mesh. No intermediate observations, retained fraction, sieve aperture or measured percentile accompanies that result.
Interpretation
The mesh result supplies the evidence beyond simple completion and packing. It supports a reported two-hour grade for this sample, while leaving complete-passage and analytical-size claims unproven. The record does not establish equivalence with another tea trial at a different setting.
Practical precautions
Resolve the paired media entry before repetition. Define the sieve method and retain a feed reference so the accepted mesh result can be compared without relying only on appearance.
TENCAN alternatives to evaluate
TENCAN Benchtop Planetary Ball Mill. A compatible benchtop machine can be assessed for the recorded tea charge. Compare at two hours using the same feed preparation and defined 200-mesh method. A benchtop comparison addresses compatible jar loading and batch handling; matching the resolved media entry keeps this from becoming an uncontrolled change in both charge and machine. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM-1 source entry; only recorded tested series/configurations are related. No jar-volume inference.
