Sample assessment
The shell was cut before the feasibility run. Powder formation is the recorded objective, with no implied extraction or chemical-conversion process. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Determine whether the supplied shell could be converted into powder.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical square planetary ball mill. The jar volume identifies the test container and does not establish an exact machine variant or production capacity. Equipment association follows the recorded machine designation.
Test setup
| Recorded planetary machine | XQM |
|---|---|
| Documented setup | 500 mL alumina jar and standard zirconia balls; 20 g cut shell; dry milling; speed setting 500. |
| Recorded operating cycle | Run 5 / pause 1; units not stated in mode field |
Speed values are reproduced as recorded settings. A rotational unit and planetary-disc versus jar-speed basis are not stated, so these numbers are not labelled rpm.
Recorded procedure and results
The shell was cut into smaller pieces before the planetary stage. After 2 hours the record states that all the material had become powder. No sieve result or particle-size percentile is supplied.
Interpretation
The qualitative result answers the recorded feasibility objective: powder formation was observed. It does not establish a micron-size limit, chemical purity, chitin extraction or a particular powder morphology. The cutting step is part of the successful preparation history.
Practical precautions
Keep cutting and milling steps separately recorded and define feed dimensions for repeat work. Add a sieve or particle-size method if a quantitative powder specification is needed, and assess wear contamination before chemical or biological analysis.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For crab shell, a matched QXQM trial can test whether changing orientation affects complete shell powder formation after the same cutting step. Keep sample mass, media and sampling times controlled. This is a proposed comparison; the test record does not demonstrate a superior result for that alternative. Confirm jar compatibility and the permitted complete loaded mass before selecting a configuration.
Procedure records XQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
