Define ore beneficiation grinding media from the intended charge distribution and the selected cast material.
Diameter schedule
The requested title span is 20–150 mm, while the detail states 20–120 mm and actual options specify individual sizes. Agree the required cast diameters and separately confirm any size absent from the chosen family.
Material acceptance
The source combines carbon steel and chromium alloy wording. Verify chemistry and casting records for the selected option instead of assuming all black spheres have the same material or mechanical condition.
- Beneficiation mill requirements
- Selected cast designation
- Actual diameter distribution
- Chemistry and route records
- Trial and inspection criteria
Recovery boundary
Review sample results under representative mill conditions before approval. Application wording establishes no mineral recovery, throughput improvement, guaranteed wear rate or certified standard compliance.
