Sample assessment
The material was supplied as tea-leaf particles. Leaf variety, drying history and moisture content were not specified.
Analyst consideration: Tea contains fibrous plant tissue, so preparation should consider fragment length and recovery as well as apparent fineness. The accepted four-hour sample does not independently characterize either attribute.
Recorded objective
Explore the milling response and obtain an acceptable sample; the record does not give the numerical acceptance criterion.
Equipment and selection
The machine entry is XQM. 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 | Corundum |
|---|---|
| Media entry | Corundum |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | Not recorded |
| Controller speed setting | 550 |
| 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
Corundum was recorded for both jar and media. Samples were taken at two hours and four hours. The four-hour sequence is explicitly marked as meeting the requirement. There are no particle-size percentiles, sieve recoveries or temperature readings in this record.
Interpretation
This is evidence of recorded acceptance for the tested tea sample. It supports the sampling sequence but does not establish a transferable four-hour recipe or a particular mesh grade.
Practical precautions
Keep drying history and feed preparation consistent. Define the acceptance measurement in advance and compare the two-hour and four-hour samples using the same method.
TENCAN alternatives to evaluate
TENCAN Compact Horizontal Planetary Ball Mill. For fibrous tea, a horizontal arrangement can be compared at the same two- and four-hour sampling points to investigate whether material movement changes the accepted preparation. The horizontal layout changes how gravity acts on the jar contents, providing a concrete way to compare circulation of fibrous tea against the recorded vertical route. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM source entry; only recorded tested series/configurations are related. No jar-volume inference.
About this trial
TENCAN laboratory trial, 2017–2020. Observations above come from this experimental record; selection considerations and proposed comparisons are engineering interpretation. Results apply to this sample and recorded conditions.
