Particle sizes for the recorded sample and sampling time.
Sample assessment
The feed combines silica powder with glass granules, so representative sampling must account for two components and more than one initial size form. A zirconia contact system was recorded. Particle-size measurements can describe the combined suspension or powder sample, but do not establish that each component was mixed to the same composition everywhere.
Recorded objective
Combine mixing and ball milling; no numerical size limit was recorded.
Equipment and selection
The source identifies XQM family. The related TENCAN product association is Vertical square planetary ball mill. This identifies the recorded equipment family, rather than an independently verified serial-number configuration. Jar contact materials and charge details below are test observations; an unspecified steel grade or ball-percentage basis is not supplied by the association.
Test setup
| Recorded setup | Zirconia jar and zirconia balls, standard charge; 51 g powder and granules; initial setting 400; run/pause cycle recorded as 5:1; interval units unspecified. |
|---|---|
| Speed notation | Values are retained as recorded speed settings. The source does not identify the revolution/rotation reference; no separate jar speed is inferred. |
Recorded procedure and results
The combined silica and glass charge ran normally at setting 400 for 60 minutes. The speed setting was then increased to 500. The 120-minute sample had D90 = 11.3 µm and the 180-minute sample was recorded at 9.7 µm; the result field identifies the latter value as D90. The duration field records three hours. The source does not establish whether the timepoints restart after the speed change, so they are retained as recorded checkpoints.
Interpretation
Both sampled values describe the coarse part of the measured distribution. The later result is finer than the earlier one, supporting a useful milling outcome alongside the intended mixing operation. No initial particle-size distribution or component-specific assay was supplied. The case therefore demonstrates the observed size evolution of the mixture, while uniform composition remains unquantified. A repeat trial could establish whether the two components grind at different rates.
Practical precautions
Preserve representative sampling of the mixed charge and use the same particle-dispersion method at both checkpoints. Confirm that zirconia contact is acceptable for the intended glass and silica application; no contamination measurement was recorded.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill: Evaluate a QXQM orientation change only if repeated samples show component segregation or uneven exposure in the silica/glass charge. Retain the zirconia contact system and the same composition assay so that a new mixing result can be assessed alongside D90. This is a recommendation for a new comparison, not an observed result of this trial.
Endpoint context: D90 = 9.7 µm, recorded 180-minute checkpoint.
Tested equipment association only: XQM family; exact machine variant not inferred. Alternative products are evaluation candidates in the body only.
