Polyurethane-Coated Iron-Core Grinding Balls
Iron-core grinding balls with a polyurethane working coating for compatible mixing, preliminary dispersion and processes that require evaluation of a cushioning surface.
Overview
Iron-core grinding balls with a polyurethane working coating for compatible mixing, preliminary dispersion and processes that require evaluation of a cushioning surface.
How it works
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.
A damaged coating can expose the iron core. Polymer wear, solvent compatibility and coating condition need to be checked.
Key features
- The core and coating perform different roles and should be specified separately.
- The published diameter range is 15–30 mm.
- The product information does not supply one fixed density for every coated configuration.
Specifications
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 properties are published references, not a certificate for a supplied batch or a complete assembly temperature/pressure rating.
Applications
Compatible mixing, pigment predispersion and slurry homogenization studies.
Suitability depends on the actual sample, process and analytical requirements; a listed application is not a guaranteed final-particle-size result.
Accessories and options
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.

Selection guidance
Match polyurethane coating over an iron core 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.

Trials and comparisons
No identifiable trial of this exact product/configuration was found in the available planetary-milling test summaries. A result from a different mill, jar grade or assistance system is not attributed to this product.
A comparison to request
For a polyurethane coating over an iron core 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.
Discuss a sample evaluationProduct FAQs
Are polyurethane-coated iron-core balls metal-free?
No. They contain an iron core. The outer coating separates it from the process only while the coating remains suitable and intact; wear inspection is part of the selection and use assessment.
Which polyurethane coating over an iron core ball diameter should I order?
The catalog diameter reference is 15–30 mm. Select diameters and the size mix around feed size, target result, jar volume and the chosen process. A damaged coating can expose the iron core. Polymer wear, solvent compatibility and coating condition need to be checked.
Can these balls replace another media material at the same mass?
The density reference for polyurethane coating over an iron core is Configuration-dependent; confirm the actual grade. Equal mass does not give equal media volume when densities differ. Define the loading basis and review the total jar load before changing materials.
How should these balls be matched to a jar?
Check the jar working surface, media hardness/density, total loaded mass and sample chemistry. A damaged coating can expose the iron core. Polymer wear, solvent compatibility and coating condition need to be checked. A diameter that fits physically is not automatically an appropriate process choice.
Does the hardness value establish wear performance in my sample?
The published hardness reference is Shore A approximately 80–95 (coating reference). A damaged coating can expose the iron core. Polymer wear, solvent compatibility and coating condition need to be checked. Assess wear with the actual sample, jar, loading and measurement method; hardness is not a sample-specific wear-rate result.
What grade and size information should I include in an inquiry?
Specify Iron core with an outer polyurethane layer, diameters within the 15–30 mm catalog reference, quantities and required grade/batch documents. Provide the actual jar, sample chemistry and contamination limits so TENCAN can review the pairing.
