In the field of industrial grinding, ball mills capable of handling 50 tons per hour (tph) or more are readily available in a variety of models. These units generally fall into the medium-to-large category and are widely used in large-scale, continuous production environments such as mining, construction materials, and chemical processing.

Key technical factors influencing throughput include shell diameter and length, motor power, grinding media charge, and material properties. For instance, a common Ф4500×6400 model processing medium-hardness materials like limestone can achieve an output of 54–306 tph, with a motor power of 2000 kW and a grinding media charge of approximately 172 tons. An even larger model, the Ф5500×8500, boasts a throughput of 108–615 tph, a 4500 kW motor, and a grinding media charge of 338 tons. Additionally, certain long-shell models with a 2.4-meter diameter (such as the Ф2400×10000) can consistently achieve capacities exceeding 50 tph when operated within a closed-circuit system.

When selecting equipment, one must consider not only throughput but also factors such as feed particle size (typically ≤25 mm), discharge fineness (adjustable between 0.074 mm and 0.4 mm), material hardness, and moisture content. It is advisable to base the overall design on specific production requirements and system integration—including classification equipment and drive mechanisms—to ensure efficient and stable operation. In summary, a throughput of 50 tph is entirely achievable with ball mills; success depends on proper model selection and scientific configuration.
