Application: mining, cement production, power plants, chemistry industries
High hardness
Good wear resistance
High impact toughness
Rear earth grinding ball available (HRC up to 60-65)
Increased Surface Contact: Their cylindrical shape provides more linear contact with material, improving grinding efficiency.
Enhanced Durability: The hot rolling and heat treatment process results in high hardness (HRC 60–65) and impact toughness, reducing wear rates.
Lower Consumption: Longer operational lifespan translates to cost savings in mining and cement industries.

Manufacturing Process
Heating: Steel billets are heated to 1,100–1,200°C to reach a malleable state. Hot Rolling: The heated steel is passed through rollers to form cylindrical shapes with rounded edges, ensuring uniformity. Heat Treatment: After rolling, Cylpebs undergo quenching (rapid cooling) and tempering to optimize hardness (for wear resistance) and toughness (to withstand impact).
Applications:
Mining: Grinding ores (e.g., copper, gold, iron) in ball mills. Cement Production: Crushing clinker and raw materials. Coal Processing: Pulverizing coal in thermal power plants. Chemical Industry: Fine grinding of minerals and pigments.
