Sample assessment
The feed was nickel acetate powder. Hydration state, starting distribution and downstream application were not identified.
Analyst consideration: For nickel acetate, hydration state and contact-derived contamination are relevant method choices because the intended grade is unspecified. A short accepted cycle should be assessed against those requirements, not fineness alone.
Recorded objective
Meet a privately controlled acceptance criterion; its numerical value was not included in the trial record.
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 | Steel 250 |
|---|---|
| Media entry | Steel 350 |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 50 (unit not stated) |
| Controller speed setting | 450 |
| 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
A steel jar and steel media were recorded. The procedure states that ten minutes was sufficient, and the result is explicitly marked as meeting the requirement. It also recommends using smaller balls where practical. No size distribution, individual ball diameter or temperature series was supplied.
Interpretation
The useful outcome is the recorded acceptance of a short test, with a source-specific preference for smaller media. It does not prove that every nickel acetate grade requires ten minutes or that a particular final particle size was achieved.
Practical precautions
Obtain the actual acceptance criterion before repeating the trial. Record the small-ball diameter and mass rather than interpreting the standard-charge entry as a reproducible media specification.
TENCAN alternatives to evaluate
TENCAN Benchtop Planetary Ball Mill. For small nickel-acetate samples, a benchtop configuration may be compared after jar and load compatibility are confirmed. Retain the ten-minute check and a fully specified small-ball charge. The benchtop comparison is about matching a verified charge to compatible jar capacity and handling; it does not imply a different grinding mechanism or inherently finer nickel acetate. 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.
