Particle sizes for the recorded sample and sampling time.
Sample assessment
The battery material is identified by application rather than exact chemistry. Its initial D50 was 8 µm, and a small 23.4 g charge was wet milled with alcohol and 1 mm zirconia balls. Selection should preserve that formulation and loading while keeping particle-size success separate from any unmeasured battery performance.
Recorded objective
A recorded D50 objective of 1 µm.
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 | XQM planetary family; 250 mL zirconia jar and 1 mm zirconia balls, standard charge; 23.4 g powder; alcohol wet milling at setting 450; 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 initial material was recorded at D50 = 8 µm. The powder was charged to the zirconia jar with 1 mm zirconia balls and alcohol. After 60 minutes at setting 450, the sample measured D50 = 0.52 µm and D90 = 0.79 µm. The duration field gives one hour and no later coarsening, caking or failed-stage observation was supplied. The exact battery-material chemistry, alcohol quantity and ball mass were not recorded.
Interpretation
The measured median is below the specified D50 value and provides evidence of a favorable outcome beyond the completion label. D90 = 0.79 µm describes the reported distribution at that checkpoint; it is not proof of a maximum particle size below 1 µm. The incoming record supplies only D50, so no initial-to-final D90 comparison is possible. No electrochemical testing or composition analysis accompanies the milling result, and neither can be inferred from the final particle sizes.
Practical precautions
Confirm the powder chemistry, alcohol compatibility and zirconia wear tolerance before reproducing the route. Record ball mass, solvent loading and sample dispersion. If downstream battery performance matters, test that performance independently after the milling and recovery steps.
TENCAN alternatives to evaluate
TENCAN Planetary ball mill (semi-circular model): Evaluate the XQM-A benchtop family for another small-charge wet battery-powder trial. Verify alcohol compatibility and the permitted zirconia contact first, and compare the median objective with any separately required chemical or electrochemical checks. This is a recommendation for a new comparison, not an observed result of this trial.
Endpoint context: D50 = 0.52 µm; D90 = 0.79 µm at 60 minutes.
Tested equipment association only: XQM family; exact machine variant not inferred. Alternative products are evaluation candidates in the body only.
