Sample assessment
The granular iron-ore sample was not characterized by mineralogy, moisture or initial distribution. The result applies to the tested material.
Analyst consideration: An ore may contain constituents with different fracture responses, so a bulk mesh acceptance does not establish mineral liberation or equal treatment of every constituent. Feed fraction and contact contamination are relevant selection considerations.
Recorded objective
Meet the recorded 600-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 250 |
|---|---|
| Media entry | Steel 300 |
| Media-charge notation | 5-75/8-60/10-65/12-5/5-5 |
| Sample-load entry | 60 (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 setup lists a steel jar and steel media. A sample taken after one hour was explicitly described as satisfying the requirement, and the result field is marked accepted. The notebook does not give a sieve percentage, aperture standard or particle-size percentiles.
Interpretation
The supported conclusion is reported acceptance at one hour. The record does not independently demonstrate 100% passage or a converted micrometre maximum, and it cannot establish a general iron-ore throughput.
Practical precautions
Confirm the acceptance method and actual sieve specification before a repeat. Keep a feed reference and record sample and media masses in explicit units when preparing a transferable method.
TENCAN alternatives to evaluate
TENCAN Horizontal light-duty ball mill. A horizontal planetary configuration can be compared for this granular iron ore. Use the same feed fraction and one-hour acceptance method rather than a nominal-capacity comparison. A horizontal layout changes the relationship between gravity and planetary motion, providing a way to compare granular-ore movement while keeping the sieve objective fixed. 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.
