Sample assessment
The material was granular barite. No mineralogical analysis, moisture or feed distribution was included.
Analyst consideration: For a mineral powder such as barite, recovery and the remaining coarse tail matter alongside the accepted mesh label. Mineralogy and actual loading must be known before transferring the result to another source.
Recorded objective
Meet the stated 800-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 1 |
|---|---|
| Media entry | Zirconia 250 |
| Media-charge notation | 352 (unit not stated) |
| Sample-load entry | 150 (unit not stated) |
| Controller speed setting | 400 |
| 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
A steel jar and zirconia media were recorded. Operation was described as normal at one hour. Samples were taken at two and three hours, and the three-hour sequence is explicitly described as satisfying the requirement. The result is marked accepted; no measured distribution or sieve-passing percentage was supplied.
Interpretation
The acceptance statement supports the reported three-hour outcome. It does not independently prove an all-particle sieve cutoff or establish a micrometre equivalent. The two-hour sample has no reported numerical result and is not assigned one here.
Practical precautions
Confirm the mesh standard and the actual acceptance method. Specify the compact media-charge notation and initial sample distribution before comparing another barite source.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. For barite, a tumbling planetary comparison can investigate sample redistribution. Keep the three-hour sample and the same 800-mesh acceptance procedure. Tumbling changes bed orientation and redistribution; a matched barite comparison can examine media contact without assigning an unmeasured settling problem to the present sample. 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.
About this trial
TENCAN laboratory trial, 2017–2020. Observations above come from this experimental record; selection considerations and proposed comparisons are engineering interpretation. Results apply to this sample and recorded conditions.
