Specify cast grinding spheres with actual material records and a defined surface acceptance requirement.
Surface inspection
The title describes a smooth surface without a roughness measurement or defect criterion. Agree the required appearance and inspection method for the supplied balls rather than treating the wording as a measured finish specification.
Alloy and hardness
Choose a listed cast alloy-size entry and verify chemistry and route. HRC45–65 is a requested title range, so obtain actual hardness records and agree applicable acceptance before approving the ore mill charge.
- Selected cast model
- Actual alloy chemistry
- Diameter and shape inspection
- Surface acceptance criteria
- Lot hardness and mill trial
Operating evidence
Review representative behavior under the intended duty. Smooth appearance and hardness wording establish no wear-rate guarantee, breakage limit or certified grinding performance.
