ultrafine ball mill

Product Introduction

Ultrafine ball mills are powder grinding and processing equipment primarily suitable for use in industries such as mining, lime, chemicals, cement, construction, and fly ash. They produce high levels of fine powder and grinding power. The grinding wheel assembly is equipped with a universal joint and spring-loaded mechanism, allowing the grinding wheel to automatically adjust to maintain parallel contact with the active roller, ensuring fine grinding and product quality.

Operating Principle

The ultrafine ball mill operates by a motor driving the main shaft and turbine at high speed. The turbine and grinding blocks on the screen ring form a compact crushing and grinding assembly. When material enters the mill from the hopper, it is closely rubbed and strongly impacted by the rotating airflow against the inner edges of the turbine blades, where it is further ground in the gaps between the blades and the grinding blocks. While crushing and grinding the material, the turbine draws in large quantities of air, which cools the machine, grinds the material, and conveys the fine material. (The degree of material grinding depends on the material's properties, the screen size, and the amount of material and air passing through.) Finally, the material is discharged through the discharge grate.

Product Advantages

1. The ultrafine ball mill boasts a high operating rate, eliminating frequent downtime for maintenance due to damage to the internal chamber structure. This reduces the manpower and material losses caused by repeated ball distribution, lowering worker intensity.

2. Technicians have optimized the ultrafine ball mill's internal structure with cutting-edge technology, reducing resistance within the machine, ensuring smoother ventilation, and achieving a more balanced particle size distribution.

3. The use of small-diameter forged steel grinding media reduces the impact of large-diameter steel balls on the ultrafine ball mill cylinder, ensuring stable operation, reducing failure rates, and extending its service life.

4. Its innovative design significantly improves pulverization efficiency, and its optimized grinding media ratio allows for the efficient production of large quantities of fine powder.

5. Liners and grinding media can be selected based on the material to ensure product purity and whiteness.

6. The ultrafine ball mill classification production line boasts significant advancements and breakthroughs in energy-saving technology and classification accuracy compared to other ball mill classification production lines.

7. The fineness of the first-stage classification is adjustable from 300 to 2500. With the addition of a classifier system, the fineness can reach d97 ≤ 2µm (6250 mesh) after secondary classification, reaching the advanced level of dry classification both domestically and internationally.
