At Cast Products South Africa, we specialise in high chrome iron castings designed specifically for the demanding environment of coal pulverising mills in power plants. Our wear-resistant castings are engineered to withstand the harsh conditions of South African coal, delivering superior durability, efficiency, and cost savings.
South African coal often contains high ash content and abrasive materials that put intense wear pressure on pulverising equipment. High chrome iron castings offer the perfect balance of hardness and toughness, making them highly resistant to abrasion and wear.
Exceptional hardness protects against grinding and impact damage
Toughness ensures durability under heavy operational loads
Resistant to thermal shock and chemical corrosion common in coal mills
These qualities make high chrome iron the preferred material for critical pulveriser components.
We manufacture high chrome iron castings for essential coal mill parts, including:
Grinding rings: Provide a wear-resistant surface for crushing coal particles
Grinding rollers: Ensure consistent pulverisation with maximum durability
Table liners: Protect mill tables from abrasion and extend service life
Solid and hollow grinding balls: Optimised for efficient grinding and reduced wear rates
Each component is precision-machined to exact specifications, ensuring perfect fit and performance in vertical spindle mills, ball mills, and E-type mills.
Cast Products South Africa has over 60 years of experience producing wear-resistant castings for coal power plants. Our advanced manufacturing processes include:
Use of high chrome white irons developed for abrasive coal conditions
Precision machining of components up to 4,260 mm in diameter and 14 metric tons in weight
Tight machining tolerances (±2.5 mm) for optimal performance
Strict quality control procedures to guarantee consistent, reliable castings
Power stations equipped with our high chrome iron castings benefit from:
Reduced downtime due to extended component life
Lower operational costs through decreased maintenance frequency
Improved mill efficiency by maintaining optimal grinding conditions
Adaptation to the unique abrasive nature of South African coal
Our castings help power plants maintain continuous, cost-effective operations in challenging environments.
We lead innovation by developing high chrome iron balls as a superior alternative to traditional alloy steel balls. Our range includes:
Solid high chrome balls: For high abrasion resistance
Hollow high chrome balls: Reduced weight with improved wear life
Chrome-molybdenum steel balls: For clients requiring enhanced impact resistance
These innovations offer power plants longer service life and improved grinding performance.
