Sample assessment
The feed was hair fibers without a starting length distribution or pretreatment description. Corundum and zirconia were recorded for jar and media.
Analyst consideration: Hair is fibrous, so a generic size reading may describe a different feature from actual fragment length. Selection should therefore consider morphology and recovered fibers alongside the reported accepted number.
Recorded objective
Meet the stated 80 µm fineness 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 | Corundum250 |
|---|---|
| Media entry | Zirconia 250g |
| Media-charge notation | 352 (unit not stated) |
| Sample-load entry | 6 (unit not stated) |
| 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
The procedure records two hours of milling without adhesion and marks the result as meeting the requirement. The result column gives 80 µm and the controller setting is 550. The source does not identify whether the size is a length, distribution percentile or another characteristic.
Interpretation
The supported outcome is a nonadhering accepted sample with a reported 80 µm result. It cannot be interpreted as a maximum fiber length or as proof that every fragment met that dimension.
Practical precautions
Clarify the measurement basis before a repeat. Preserve feed pretreatment and inspect morphology as well as any reported particle-size number when evaluating fibrous material.
TENCAN alternatives to evaluate
TENCAN Compact Horizontal Planetary Ball Mill. For hair fibers, a horizontal arrangement can be compared using the same preparation and two-hour acceptance method. Measure the relevant fiber dimension rather than relying only on a generic size number. The horizontal arrangement changes how gravity acts on fibers and media, making circulation and the residual fiber population concrete comparison points at two hours. 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.
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.
