This customer contacted our company in 2016 and inquired about calcite powder making plant for 10microns powder production. After 3months’communication, their representative visited our production base and deeply impressed by our company’ strength, finally they bought our XZM236 ultrafine mill. Because our mills run very smoothly during these years, they bought another two XZM236 ultrafine mills in 2020. Now the mills are reaching customer’s factory and soon they will be built up for new production. Their powder main application is used as filler for paint industry.
