Sample assessment
The source identifies only a pharmaceutical powder. The active ingredient, formulation and initial particle-size distribution are not given.
Analyst consideration: For a pharmaceutical powder, size reduction can be accompanied by changes in solid form or composition. Jar-contact choice and sample temperature should therefore be evaluated alongside the accepted physical endpoint.
Recorded objective
Make the powder finer; no numerical endpoint was specified.
Equipment and selection
The machine entry is WXQM. 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 | PTFE |
|---|---|
| Media entry | Zirconia |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | Not recorded |
| 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 WXQM horizontal planetary machine, PTFE jar and zirconia media were recorded. The procedure states that one hour was sufficient. The media charge is described only as standard, and no final size, assay, dissolution or sample-temperature measurement accompanies the acceptance statement.
Interpretation
The evidence supports a material-specific accepted operating observation on the horizontal platform. It does not prove a particular pharmaceutical quality attribute or establish that a horizontal machine is better than a vertical one.
Practical precautions
Confirm the formulation and define the actual acceptance test before repeating. Record the standard charge as individual diameters and masses and inspect recovered material for any retained deposits.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. Assembly tumbling is a separate motion to compare for the pharmaceutical formulation. Match the PTFE and zirconia arrangement and the one-hour acceptance test. QXQM adds assembly tumbling to planetary motion and can compare material redistribution with the recorded horizontal layout; this is a motion question, not a pharmaceutical-quality claim. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit WXQM 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.
