PLANETARY BALL MILLS
An alumina ceramic jar for planetary milling of compatible nonmetallic samples.
An alumina ceramic jar for planetary milling of compatible nonmetallic samples. The product information also identifies zirconia media as a pairing to evaluate, without making that combination a universal recipe.
The jar working surface forms part of the contact system between sample, media and mill. Material selection should balance the required mechanical action with chemical compatibility and the acceptable contribution from wear.
Check aluminium contamination limits and the sample chemistry. Do not translate a ceramic material’s thermal capability into a complete jar, seal or mill operating limit.
Published catalog references are reproduced below. Nominal volume is not a sample-mass rating. Confirm the selected model, material grade, electrical supply and complete supplied configuration in the quotation.
| Model / nominal volume | External diameter (mm) | Height (mm) |
|---|---|---|
| 50mL | 56 | 70 |
| 100mL | 70 | 72 |
| 250mL | 95 | 88 |
| 500mL | 106 | 112 |
| 1000mL | 133 | 131 |
| 1500mL | 132 | 141 |
| 2000mL | 132 | 173 |
Ceramic raw materials, minerals and compatible laboratory powders where alumina contact can be accepted.
Suitability depends on the actual sample, process and analytical requirements; a listed application is not a guaranteed final-particle-size result.
Confirm jar dimensions, lid and holder compatibility, and ask for the supplied alumina grade rather than assuming it from appearance.
State the required grade, quantities, drawings and destination when requesting a quotation. Confirm what is included, the document requirements, packing and commercial terms; no generic delivery time or universal custom capability is assumed.

Match alumina (corundum) to the sample chemistry and the elements or residues that matter to the analysis. Then confirm the dimensions, complete loaded mass and operating arrangement against the selected mill.

Two starting grades appear in the entry, so no starting distribution is assigned to these measured samples. Jar/media grade, interruption history and measurement method are unspecified. This supports a material-level comparison of recorded time points, not proof of a premium-jar advantage.
For a alumina (corundum) comparison, use matched sample portions and the same measurement/dispersion method. State the jar, media, mass/volume loading basis, processing schedule and contamination measurements. A change in material grade alone is not established as the cause of a result.
These anonymous records are not operating instructions. Measurement and dispersion methods are not fully specified in the test summaries; results apply to the reported samples and conditions.
Discuss a matched sample evaluationCorundum is the crystalline alumina material described by the source. “Alumina (corundum)” makes the material clear to an international equipment buyer; the actual grade still needs confirmation.
Listed nominal volumes: 50mL, 100mL, 250mL, 500mL, 1000mL, 1500mL, 2000mL. Check external diameter, complete lid-inclusive height, holder/clamp geometry and loaded mass. Confirm jar dimensions, lid and holder compatibility, and ask for the supplied alumina grade rather than assuming it from appearance.
No. Allow space for media and material movement, and check the permitted loaded mass. Check aluminium contamination limits and the sample chemistry. Do not translate a ceramic material’s thermal capability into a complete jar, seal or mill operating limit. Agree the charge for the actual alumina (corundum) jar and process.
Consider the sample chemistry, the jar working material, contamination limits and the required result. Check aluminium contamination limits and the sample chemistry. Do not translate a ceramic material’s thermal capability into a complete jar, seal or mill operating limit. Confirm the complete pairing before specifying a diameter mix or media charge.
Confirm jar dimensions, lid and holder compatibility, and ask for the supplied alumina grade rather than assuming it from appearance. A proposed custom feature is subject to engineering confirmation and is not automatically included with a standard jar.
Silica: XQM; exact model not recorded, 176 g in 500 mL alumina/corundum jar, 45 min. This is an XQM-family record, not verification of every XQM model. The requested 1 µm target was not demonstrated. Exact ceramic/media grades and measurement/dispersion methods are not supplied. A material-family observation does not certify the supplied part or grade.
