Sample assessment
The material was granular boron oxide. No composition details, initial distribution or moisture specification were supplied.
Analyst consideration: For boron oxide, atmosphere, material condition and tooling contact are distinct selection variables. A favorable argon-jar observation does not establish that oxygen exclusion rather than charge differences caused the improvement.
Recorded objective
Observe the milling response; no numerical fineness criterion was entered.
Equipment and selection
The machine entry is WXQM-2. TENCAN Horizontal light-duty ball mill is associated at the recorded series level. The association is a WXQM laboratory reference; the record does not independently specify every supplied machine feature.
Test setup
| Jar entry | Steel 500 |
|---|---|
| Media entry | Zirconia 500 |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 110 (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 machine entry is WXQM-2. A steel jar and zirconia media were recorded. The procedure used a vacuum-type jar filled with argon and continued for four hours. It records no adhesion and describes the atmosphere-assisted material result as substantially better. No gas pressure or final size was supplied.
Interpretation
The favorable observation concerns this four-hour jar arrangement. The note does not establish a controlled inert-atmosphere advantage because matched reference conditions were not given. A vacuum-type closure and an argon-filled operating atmosphere are distinct descriptions.
Practical precautions
Confirm jar sealing, permitted pressure and atmosphere procedure for the selected configuration. Record the actual final distribution if a fineness comparison is required.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. An full-directional machine with a compatible sealed jar can be evaluated for boron-oxide movement. Match the argon procedure and four-hour check; no atmospheric advantage is assumed. QXQM changes assembly orientation while retaining planetary motion, allowing redistribution to be compared separately if the same compatible argon closure and material preparation can be specified. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit WXQM-2 source entry; only recorded tested series/configurations are related. No jar-volume inference.
