Sample assessment
The feed was muscovite at approximately 20 mesh. A preceding roller-mill sequence was followed by a planetary test using zirconia jar and media.
Analyst consideration: Muscovite can be assessed for flake morphology as well as apparent fineness; the recorded roller D50 cannot establish the planetary distribution. Its intended use determines whether preserving or breaking flakes is preferable.
Recorded objective
Meet the recorded 325-mesh requirement.
Equipment and selection
The successful stage is explicitly planetary, but its exact family and model are not recorded. TENCAN Laboratory planetary grinder is supplied as a catalog platform reference only; it is not identification of the tested machine.
Test setup
| Planetary-stage jar | Zirconia; capacity not recorded |
|---|---|
| Planetary-stage media | Zirconia balls; mass not recorded |
| Planetary-stage charge | Not recorded |
| Planetary-stage sample load | Not recorded |
| Planetary-stage speed setting | Not recorded |
| Planetary-stage cycle | Not recorded |
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 preceding roller stage used a 700 g charge. At setting 270 and sixty minutes there was little change. After increasing to 350, D50 was 72.7 µm at 120 minutes and 32 µm at 240 minutes. The procedure then changed to a planetary mill with zirconia jar and zirconia balls and describes the result as very good. The result field is marked accepted. No separate planetary duration, load or measured size was given.
Interpretation
The favorable accepted outcome is attributable to the named planetary stage, while the D50 numbers belong to the preceding mill. They must not be relabeled as planetary results or converted to complete 325-mesh passage.
Practical precautions
Identify the planetary family and recover the actual stage conditions before repetition. Define a sieve or distribution acceptance method appropriate to muscovite morphology.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. A QXQM comparison can investigate muscovite redistribution after the actual successful planetary configuration has been recovered. Define the 325-mesh acceptance check before comparing motion or duration. QXQM adds assembly tumbling and therefore changes flake-bed redistribution, providing a concrete motion comparison once the accepted source stage and sieve criterion are fully specified. This is an untested comparison proposal, not a result of this trial.
Exact successful planetary family/model not recorded; the TENCAN Laboratory planetary grinder catalog page is a catalog platform reference only.
