Sample assessment
The feed was granular silica. Its mineral form and starting size distribution were not supplied.
Analyst consideration: For silica, fracture and agglomerate breakup can both affect a reported fineness outcome. The steel-jar/agate-media combination also makes contact-derived material a separate consideration from mesh acceptance.
Recorded objective
Meet the stated 600-mesh requirement.
Equipment and selection
The machine entry is XQM. 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 | Agate160 |
| Media-charge notation | Standard charge; individual specification not recorded |
| Sample-load entry | 60 (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 record lists a steel jar with agate media. Water, 40 g, was added for the trial. At one hour the sample was explicitly described as meeting the requirement, with an accepted result entry. No individual particle-size statistic or sieve-passing percentage was recorded.
Interpretation
The favorable observation is a one-hour accepted wet trial. The mesh requirement remains in its original form because neither a sieve standard nor an aperture was specified. The unusual steel-and-agate combination is recorded rather than replaced with a conventional matched material pair.
Practical precautions
Check jar and media compatibility and document the actual charge. Confirm the particle-size or sieve acceptance procedure before transferring this result to another silica grade.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. For silica, an full-directional wet trial can compare suspension movement with the same 40 g water addition. Preserve the recorded one-hour check and specify the 600-mesh method. Tumbling changes the redistribution of the water-containing charge, allowing a focused comparison of suspension movement while the recorded tooling and water addition remain controlled. 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.
