Hunan province is rich in limestone and calcite mineral resources. The client's main business is processing building material fillers, putty powder, and concrete admixture powders. Their existing aging grinding equipment suffered from four major drawbacks: insufficient capacity, large fluctuations in finished product fineness, excessive dust, and high energy consumption, making it unable to meet the continuously growing order demand and local environmental control standards.

After visiting several heavy equipment manufacturers and comparing their equipment capacity, wear life, operation and maintenance costs, complete set delivery, installation, and after-sales service capabilities, the client ultimately selected Shanghai Dingbo Heavy Industry to customize a complete powder production line using the YGM1600 high-pressure grinding mill.
