PLANETARY BALL MILLS
304 stainless-steel grinding balls for milling and dispersion where the sample can tolerate the relevant steel constituents.
304 stainless-steel grinding balls for milling and dispersion where the sample can tolerate the relevant steel constituents. Select the diameter and total charge with the jar and machine loading limits.
The grinding media 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.
Media wear can introduce Fe, Cr and Ni. Magnetic response and corrosion behaviour depend on the actual grade and condition.
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.
| Property | Reference |
|---|---|
| Material | 304 stainless steel |
| Composition / grade | Fe–Cr–Ni stainless steel; grade 304 |
| Diameter range | 1–30 mm |
| Density | Approximately 7.9 g/cm³ |
| Hardness | HRC 20–30 (published reference) |
| Supplied size distribution | Specify the required diameters and quantities |
| Grade / batch documentation | Confirm with the quotation; material references are not a batch certificate |
Material properties are published references, not a certificate for a supplied batch or a complete assembly temperature/pressure rating.
Compatible general powders, chemical raw materials and blending or dispersion work.
Suitability depends on the actual sample, process and analytical requirements; a listed application is not a guaranteed final-particle-size result.
Specify the media grade, diameter mix, total charge and required documentation against the actual jar and sample. Confirm custom requirements in the quotation.
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 304 stainless steel 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.

Settling was reported and the requested sub-1 µm target was not demonstrated. The record does not establish that the jar or media were grade 304; it is a steel-family observation, not a grade-specific test.
For a 304 stainless steel 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 evaluationDo not use that as a guaranteed purchasing assumption. The product information itself notes that processing can affect magnetic response. State any magnetic or analytical requirement in the inquiry.
The catalog diameter reference is 1–30 mm. Select diameters and the size mix around feed size, target result, jar volume and the chosen process. Media wear can introduce Fe, Cr and Ni. Magnetic response and corrosion behaviour depend on the actual grade and condition.
The density reference for 304 stainless steel is Approximately 7.9 g/cm³. Equal mass does not give equal media volume when densities differ. Define the loading basis and review the total jar load before changing materials.
Check the jar working surface, media hardness/density, total loaded mass and sample chemistry. Media wear can introduce Fe, Cr and Ni. Magnetic response and corrosion behaviour depend on the actual grade and condition. A diameter that fits physically is not automatically an appropriate process choice.
The published hardness reference is HRC 20–30 (published reference). Media wear can introduce Fe, Cr and Ni. Magnetic response and corrosion behaviour depend on the actual grade and condition. Assess wear with the actual sample, jar, loading and measurement method; hardness is not a sample-specific wear-rate result.
Specify Fe–Cr–Ni stainless steel; grade 304, diameters within the 1–30 mm catalog reference, quantities and required grade/batch documents. Provide the actual jar, sample chemistry and contamination limits so TENCAN can review the pairing.
