Sample assessment
The licorice feed is fibrous, and residual roots remained after the earlier roller trial. The planetary trial used a much smaller 40 g charge and an intervening 5-mesh preparation step. Those changes matter when selecting a repeat setup because complete powder formation belongs to this prepared charge and planetary stage.
Recorded objective
Produce powder; the record explicitly marks the planetary stage as meeting the requirement.
Equipment and selection
The source identifies Unspecified planetary machine; catalog platform reference only. The related TENCAN product association is Laboratory Planetary Grinder. 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 | Planetary machine with exact family/model unspecified; stainless steel jar and steel balls; 40 g fibrous feed; setting 450; dry milling. The source lists QM-5 for the earlier roller comparison, so its equipment heading is not used to identify the planetary machine. |
|---|---|
| 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 earlier roller-mill run used 300 g licorice at setting 450. After two hours the condition was considered fairly good, but at four hours some roots remained unground and only 90% passed a 50-mesh sieve. The planetary stage used 40 g licorice and a stainless steel jar with steel balls. The procedure says that coarse material was separated using a 5-mesh sieve before further milling. After 60 minutes at setting 450, the sample was entirely in powder form and completely passed the 50-mesh sieve. The overall duration field records five hours.
Interpretation
The successful stage is explicitly attributable to a planetary machine and has direct sieve evidence. Its outcome is kept separate from the earlier roller result with residual roots. The much smaller planetary charge and the feed-selection step prevent a controlled efficiency comparison between the machines. The note does not specify which fraction from the 5-mesh preparation was retained, so reproducing the feed preparation requires clarification. No claim of a particular particle diameter is derived from the mesh designation.
Practical precautions
Identify the actual planetary model and retained feed fraction before reproducing this route. Record charge recovery and any fibrous residue alongside sieve passing mass. Check whether steel contact is acceptable for the intended use and confirm that the sieve test represents the whole recovered charge.
TENCAN alternatives to evaluate
TENCAN Vertical Planetary Ball Mill: Evaluate an identified XQM vertical model for a repeat of the small licorice charge, since the successful planetary family is unknown. Retain feed selection and direct 50-mesh testing before comparing cycle time or attempting a larger fibrous batch. This is a recommendation for a new comparison, not an observed result of this trial.
Endpoint context: Planetary stage at 60 minutes: powder formed; complete passage through a 50-mesh sieve.
Tested equipment association only: Unspecified planetary machine; catalog platform reference only; exact machine variant not inferred. Alternative products are evaluation candidates in the body only.
