Sample assessment
The feed was alumina powder with a recorded initial size of 33 µm. The source does not label this number as a distribution percentile.
Analyst consideration: For alumina, the characteristic-size reduction is informative only when the initial and final measurements use the same preparation. Steel contact may also need assessment if the intended ceramic process limits introduced metals.
Recorded objective
Reach a recorded 13 µm endpoint.
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 100 |
|---|---|
| Media entry | Steel 140g |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 19 (unit not stated) |
| Controller speed setting | 500 |
| 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 setup lists a steel jar and steel media. Water, 10 g, was added for wet milling. After thirty minutes the sampled size was 13 µm, matching the target and result entries. No other sampling times, distribution percentiles or temperature data were supplied.
Interpretation
The record provides a directly comparable initial and final characteristic size, while leaving the analytical method unspecified. It does not establish an all-particle 13 µm limit or show that the reduction was uniform across the distribution.
Practical precautions
Confirm the original measurement definition before repeating. Keep water addition and sampling preparation consistent and evaluate contamination separately where the intended alumina application requires it.
TENCAN alternatives to evaluate
TENCAN Benchtop Planetary Ball Mill. A compatible benchtop setup can be compared for the alumina charge with 10 g water. Keep the thirty-minute sample and the same characteristic-size measurement. The benchtop comparison concerns compatible jar loading and handling for the verified laboratory charge; keeping the water addition and measurement constant avoids attributing charge effects to the housing. 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.
