In recent years, high-value ultra-fine barite powder (600–2500 mesh) has been widely used in functional fillers, coatings, plastics, cosmetics and new materials. Traditional mills cannot meet the fineness and purity requirements. The LUM Ultrafine Vertical Mill has become the ideal equipment for producing ultra-fine barite powder.
The LUM ultrafine vertical mill integrates grinding, drying, classification and collection. It uses multiple grinding rollers and a high-speed rotating classifier to achieve precise particle size control. The finished powder has narrow particle size distribution, high purity and good dispersity.
One of the most important advantages is low iron contamination. Barite ultra-fine powder requires extremely high whiteness. The LUM mill’s grinding chamber uses wear-resistant composite materials, which effectively avoid black impurities and ensure product quality.
In addition, the LUM mill features low energy consumption. Compared with other ultra-fine grinding equipment, it saves 20–40% electricity. Its intelligent control system supports automatic operation, remote monitoring and fault alarm, reducing labor intensity.
The production process of ultra-fine barite powder is as follows:
Crush raw barite to less than 10mm.
Feed into LUM ultrafine vertical mill.
Grind and classify under high-speed airflow.
Collect qualified ultra-fine powder.
Package finished products automatically.
The whole line is highly automated and environmentally friendly. Many barite deep processing enterprises have upgraded their production lines with LUM mills and achieved higher product added value.
Shanghai Shibang provides complete ultra-fine barite processing solutions, including equipment selection, plant design, installation, commissioning and after-sales service.
