Sample assessment
The feed was hard-alloy powder recorded as 50–100 mesh. Exact composition and the feed distribution were not supplied.
Analyst consideration: For hard-alloy powder, media wear and material deformation or fracture depend on the actual composition. The recorded D90 and jar temperature should therefore be evaluated alongside contamination and morphology requirements.
Recorded objective
Meet a recorded 10–20 µm requirement.
Equipment and selection
The machine entry is QXQM. TENCAN Omnidirectional Planetary Ball Mill is associated at the recorded series level. A horizontal operating mode, where mentioned, does not change the recorded QXQM family into WXQM.
Test setup
| Jar entry | Hard alloy jar |
|---|---|
| Media entry | Hard alloy balls |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 300g |
| Controller speed setting | 400 |
| 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 QXQM trial used a hard-alloy jar and hard-alloy media. A 300 g charge was dry milled at setting 400. At 280 minutes the inside-jar temperature was 68 °C and the sampled distribution had D90 = 11.3 µm. The result is explicitly marked accepted.
Interpretation
The final D90 is the specific measured endpoint and lies within the numerical target interval. It is not an all-particle range or a purity result. The 68 °C reading is relevant process evidence rather than proof of temperature control.
Practical precautions
Confirm the exact hard-alloy composition and temperature limit. Record the standard media charge in explicit dimensions and masses before repeating the accepted 280-minute test.
TENCAN alternatives to evaluate
TENCAN Vertical Planetary Ball Mill. A conventional vertical platform can compare the hard-alloy powder with the same tooling and 280-minute endpoint. Measure inside-jar temperature and D90 under matched loading. A conventional vertical platform omits QXQM assembly tumbling, providing a focused comparison of redistribution when the same hard-alloy contact materials and load are retained. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit QXQM source entry; only recorded tested series/configurations are related. No jar-volume inference.
