Barite has a relatively high true density, and during grinding its slurry load is significantly higher than that of many common non‑metallic minerals. Consequently, the design of vertical ultrafine mills cannot simply adopt the parameter settings used for low‑density materials such as calcium carbonate. Once the slurry enters the fine‑grinding equipment, the motion of the grinding media is influenced not only by the agitator but also by the material’s density, solids content, and flow rate. If the circulation capacity is inadequate, high‑density particles may become concentrated in localized zones, leading to fluctuations in load; and if the media selection is suboptimal, energy efficiency will suffer while wear rates increase. For barite fine grinding, the proportion of large balls should be determined based on the feed particle size, while the proportion of small balls should be tailored to the target fineness. At the same time, the spindle torque, motor power, and the capacity of the circulation system must all be carefully evaluated.

The cell mill employs a vertical stirred wet‑grinding configuration and can accommodate various media combinations tailored to high‑density mineral powders such as barite. During operation, it is recommended to continuously monitor the main motor current, slurry flow rate, outlet particle size, and temperature to identify stable operating conditions, rather than relying solely on a single particle‑size analysis to assess equipment performance.
