Sample assessment
The granular magnesium-oxide sample was not characterized by grade or initial distribution. Steel was recorded for both the jar and media.
Analyst consideration: For magnesium oxide, fragment reduction and agglomerate breakup are different possible sources of a favorable powder result. A feed-to-product distribution and contact-contamination check would make the acceptance more informative.
Recorded objective
Observe the milling response and obtain an acceptable sample; no numerical fineness target was entered.
Equipment and selection
The machine entry is XQM. TENCAN Vertical 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 | 100 (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 source states that thirty minutes was sufficient to meet the requirement, and the result field is marked accepted. The controller setting is recorded as 500. No intermediate samples, D50, D90, sieve fraction or sample-temperature result were supplied.
Interpretation
The positive evidence is the explicit acceptance of this thirty-minute trial. It establishes a useful comparison time for the tested sample, but not a particular final particle size or an oxide-wide grinding rate.
Practical precautions
Define the missing acceptance criterion and record actual charge units before repeating. Compare a retained feed sample with the recovered material using the same analytical preparation.
TENCAN alternatives to evaluate
TENCAN Benchtop Planetary Ball Mill. A benchtop configuration can be compared for this magnesium-oxide sample if the jar and loaded mass fit. Preserve the thirty-minute endpoint and define the missing fineness criterion. The benchtop option addresses compatible jar capacity and batch handling for a laboratory comparison, while the same thirty-minute check prevents nominal machine size from being mistaken for process performance. 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.
