Testing Proves Milling Goal Possible for TiO2 Producer

HANOVER, MA – With the halt of growth in construction projects in China, CNNC had a problem. One of their brands, Hao pu, focused on TiO2 processing with the end product primarily being used in the creation of construction materials and with demand dwindling they had to seize other opportunities. To aid them in shifting focus, CNNC worked closely with Sturtevant with the goal of producing higher quality TiO2 that could be exported and sold internationally opening up countless new markets.CNNC Steam Micronizers

The result of the collaboration between CNNC and Sturtevant was the delivery of nine 42″ Micronizers with capacities of de-agglomerating four tons per hour. CNNC chose the TiO2 Steam Micronizers after a series of testing and comparisons against other jet mill manufacturers. They needed a jet mill that would not affect the color of the bright white pigment which due to its abrasive nature can easily become contaminated during the milling process. Thanks in part to their full-service testing facility at their headquarters in Hanover, MA, Sturtevant was able to provide data and recommendations, including PureLine liners designed specifically for TiO2, that proved CNNC’s goal was possible.

Rich Robatzek, Product Manager for the Micronizer at Sturtevant, explains that coming up with solutions to unique applications “is always exciting as it not only helps our customers but also gives us key insights into a machine invented over 60 years ago.” Collaborating with customers like CNNC to improve their milling results is always a welcome challenge for Sturtevant.
