Sample assessment
The feed was identified as a 100-mesh magnetic powder. No specific alloy composition or magnetic-property acceptance was supplied.
Analyst consideration: For magnetic powder, the explicit sieve endpoint is useful because a median alone could conceal coarse retained material. Tooling contamination and magnetic properties still need their own acceptance criteria.
Recorded objective
Meet the 325-mesh requirement using a sieve measurement.
Equipment and selection
The machine entry is XQM-1. TENCAN Vertical square 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 250 |
|---|---|
| Media entry | Steel 350 |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 123 (unit not stated) |
| Controller speed setting | 550 |
| 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 source states that the powder was insoluble in water and that an instrumental particle-size measurement was unavailable, so a sieve was used. There was no adhesion at thirty minutes or two hours. At four hours all material passed the 325-mesh sieve. Steel jar and media were recorded.
Interpretation
The all-passing sieve observation directly supports the stated check. The recorded reason for using a sieve is retained as a source observation, not a general claim that insoluble powders cannot be measured instrumentally. No magnetic-property improvement was tested.
Practical precautions
Record sieve standard, sample recovery and retained mass when repeating. Keep the physical fineness check distinct from magnetic performance and contamination acceptance.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. For the magnetic powder, an full-directional comparison can retain the four-hour complete 325-mesh check. Keep recovery and magnetic-property acceptance distinct from the motion comparison. Assembly tumbling changes bed reorientation, giving a defined material-movement comparison while complete sieve passage and recovered mass remain the physical endpoints. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM-1 source entry; only recorded tested series/configurations are related. No jar-volume inference.
