Particle sizes for the recorded sample and sampling time.
Sample assessment
This is an 800 g alloy-powder charge with 1,600 g alloy balls in a recorded 500 mL stainless steel vacuum jar. The alloy identity and incoming distribution are absent. The measured first charge can be described, while actual loading compatibility and atmosphere remain questions for a repeat with the identified equipment.
Recorded objective
No particle-size objective was recorded; the report describes the measured outcome only.
Equipment and selection
The source identifies XQM family. The related TENCAN product association is Vertical 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; 500 mL stainless steel vacuum jar; 1,600 g alloy balls and 800 g powder; dry milling at setting 500; run/pause cycle recorded as 10:2; interval units unspecified. Jar type alone does not establish vacuum operation. |
|---|---|
| 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 first charge was dry milled in the recorded stainless steel vacuum jar using alloy balls. At the 200-minute checkpoint the sample gave D50 = 3.41 µm and D90 = 6.56 µm. Two further charges were stated to be completed to the requested procedure, but their settings and measured outcomes were not supplied. The overall duration field records ten hours and 40 minutes. That overall duration is not assigned to the measured first-charge sample.
Interpretation
The first charge has a favorable reported micron-scale distribution with no adverse observation and no unresolved numerical size objective. It can therefore be described as an observed milling endpoint, without claiming a reduction ratio or customer-specific compliance. The source gives no initial distribution or alloy identity. Its measured result must not be copied to the other two charges merely because they were completed. The ball-to-powder mass ratio for the documented charge is 2:1, directly calculated from its recorded masses.
Practical precautions
Confirm actual jar loading capacity and safe balance from the machine documentation before reproducing this dense charge. Identify the alloy and clarify atmosphere requirements. Record sampling basis and check contact wear; the source supplies no chemical-purity or recovered-yield measurement.
TENCAN alternatives to evaluate
TENCAN Production-Scale Planetary Ball Mill: Evaluate a production-scale XQM family only if a larger alloy batch is required. First confirm the present jar loading and alloy identity; preserve ball-to-powder ratio as a recorded comparison variable while independently validating capacity, balance and the measured distribution. This is a recommendation for a new comparison, not an observed result of this trial.
Endpoint context: First charge at 200 minutes: D50 = 3.41 µm; D90 = 6.56 µm.
Tested equipment association only: XQM family; exact machine variant not inferred. Alternative products are evaluation candidates in the body only.
