Cast Balls
Cast balls are widely used as grinding media in mineral processing and cement manufacturing. Produced through controlled casting, they deliver reliable wear performance, consistent hardness and cost-effective operation across Ball Mill and SAG Mill circuits — available as cast iron, cast steel or high-chrome variants.
Grinding Media Balls Chemical Composition
The performance of cast balls is heavily influenced by chemical composition. Typical formulations control carbon, chromium, silicon, manganese and molybdenum levels — determining hardness, impact resistance, microstructure stability and wear performance. Selecting the right alloy is essential for optimal results in a given grinding environment.
Product Overview
BMB supplies cast grinding balls for mining companies, cement plants, distributors and grinding-media importers. Available in multiple alloy grades and diameters, they support efficient grinding while maintaining consistent quality and performance.
Technical Specifications
Diameters from 17 mm to 150 mm; hardness 50–67 HRC depending on alloy and heat treatment. Products undergo chemical analysis, hardness testing, impact testing and dimensional inspection to meet industrial quality standards.

Manufacturing Process
Production begins with raw-material preparation and alloy melting. Molten metal is poured into precision moulds, then balls are heat-treated, finished, inspected and packed — achieving the required hardness, wear resistance and dimensional accuracy.
Performance Comparison
| Property | Cast Balls | Forged Balls |
|---|---|---|
| Manufacturing Method | Casting | Forging |
| Wear Resistance | High | High |
| Cost Efficiency | Excellent | Good |
| Dimensional Consistency | Excellent | Excellent |
