10-50mm High-Efficiency Grinding Cylpebs are precision-engineered cylindrical grinding media designed exclusively for ball mills, delivering superior comminution performance across industrial sectors. Crafted via advanced metal mold casting and oil quenching heat treatment, these cylpebs feature a uniform microstructure that enhances wear resistance and energy transfer efficiency. Unlike traditional grinding balls, their cylindrical shape increases contact area with materials, boosting grinding efficiency while reducing energy consumption. Ideal for both wet and dry grinding processes, they maintain stable gradation during operation to minimize downtime for media replenishment.
High-Chrome Alloy Composition: Adopts premium high-chrome cast iron with optimized carbide distribution, achieving HRC 58-63 surface hardness—2x more wear-resistant than conventional low-chrome media.
Precision Heat Treatment: Metal mold rapid cooling combined with oil quenching creates a fine-grained matrix, ensuring impact toughness ≥4.0J/cm² and crushing rate ≤0.3%.
Efficient Energy Transfer: Cylindrical geometry improves contact efficiency, raising impact kinetic energy conversion rate from 65% to 82% compared to spherical media.
Stable Gradation Maintenance: Strict size tolerance (±0.5mm) preserves optimal particle distribution, extending ball replenishment cycles by 30%.
Low Environmental Impact: Reduces grinding dust emission by 15% and cuts mill noise by 8dB through smooth surface design.
Size Range: 10mm-50mm (customizable in 5mm increments)
Diameter Tolerance: ±0.5mm
Length-Diameter Ratio: 1.0-1.2 (optimized for ball mill rotation)
