Organic bentonite is widely used as a rheological additive in coatings, inks, oil drilling fluids, and cosmetics. To meet the growing demand for high-performance, ultrafine organic bentonite powder, a leading chemical manufacturer in China partnered with Epic Powder to achieve superior particle size reduction while maintaining high production efficiency. The customer needed to process ultra-fine bentonite with strict requirements. However, traditional mechanical mills caused excessive temperature rise that damaged the organic coating and resulted in inconsistent particle size distribution. Epic Powder recommended the MQW20 fluidized bed jet mill for bentonite, known for its precision classification and low-temperature grinding characteristics.
After commissioning and process optimization, the long-term production data is stable. The narrow particle size distribution and cool grinding process perfectly preserved the organic modification layer, significantly improving the thickening efficiency and suspension performance of the final product.
The customer reports that the MQW20 jet mill not only exceeded their fineness and capacity targets but also reduced energy costs by over 30 % compared to their previous impact mill system.
“Epic Powder’s MQW20 delivers exceptional stability and precision. Since installation, we have achieved consistent D97 below 16 microns at nearly 500 kg/h — far beyond our expectations,” said the plant manager.
This successful case once again proves that Epic Powder’s fluidized bed jet mill technology is the ideal choice for high-value, heat-sensitive materials such as organic bentonite.
