Máquinas de pó épico de Qingdao Co., Ltd. é um profissional fabricante of powder processing equipment. Our products mainly include: powder grinding equipment, classification equipment, equipamento de modificação e equipamento auxiliar relacionado.
Among the products, our grinding equipment includes: moinho de rolos, jet mill, moinho de bolas, air classifier mill, vibration mill, etc. Based on our company’s many years of practical production experience and feedback from consumers, we have made a general comparison and selection guide for roller mill, jet mill and ball mill. We hope it can be of some help to powder processing enterprises in the selection of the three mills.
Comparison of the characteristics of the three
| Parameter | Moinho de rolos | Moinho de jato | Moinho de bolas |
| Grinding principle | Roller-ring extrusion and shearing | High-speed airflow impact and collision | Steel balls/ceramic balls impact grinding |
| Consumo de energia | Low (30-50% lower than ball mill) | Very high (2~3 times that of roller mill) | High |
| Heat-sensitive material | Partially applicable (air cooling temperature control) | Very suitable (low temperature grinding) | Not applicable (easy to heat up) |
| Metal contamination risk | Low | No | High |
| Maintenance costs | Medium (replace the roller sleeve regularly) | Low (no wear of moving parts) | High (frequent liner/balls change) |
| Application areas | Non-metallic minerals, building materials, chemicals | Medicine, lithium batteries, high-purity materials | Mining, cement, ceramics |
Key factors for selection
· Material characteristics
— High hardness materials (Mohs hardness ≥ 7)
✖ Roller mill (roller wears quickly)
✔ Jet mill (non-contact grinding), or ball mill (ceramic lining)
Examples: Silicon carbide, corundum
— Heat-sensitive/sticky materials
✔ Jet mill (low temperature, no adhesion)
✖ Ball mill (severe temperature rise), roller mill should be based on actual conditions
Examples: Vitamins, resins
· Product fineness
— Ultra-fine powder (D97 ≤ 5μm)
✔Preferred jet mill (narrow particle size distribution)
— Medium fine powder (10~100μm)
✔ Roller mill (most cost-effective)
— Coarse powder（＞100μm）
✔Ball mill (strong adaptability)
· Capacity and cost
— Small-batch high-value-added products
✔ Jet mill (high precision, suitable for medicine/lithium battery)
— Large-scale continuous production
✔ Roller mill (low energy consumption) or Ball mill (large production capacity)
— Limited budget
✔ Roller mill or ball mill
Typical industry application recommendations
| Industry | Preferred equipment | Alternatives | Reason |
| Lithium battery materials | Moinho de jato | Roller mill+air classifier | Ultra-fine and pollution-free powder is required |
| Cement slag powder | Moinho de rolos | Vertical mill | Energy saving and specific surface area meets the standard |
| Pharmaceutical intermediates | Moinho de jato | Vibration mill | Low temperature and no metal pollution |
| Ceramic glaze | Moinho de bolas | Moinho de rolos | More coarse grinding needs with low cost |
To sum up what has been said above, it is: Ultra-fine high-purity selecting jet mill, large-scale energy saving selecting roller mill, cost-effective coarse grinding selecting ball mill.
