Barite (BaSO4) is one of the most important non-metallic mineral resources widely used in oil drilling, paint, rubber, plastics, construction, chemical engineering and other industries. As the demand for high-purity and fine barite powder continues to grow worldwide, efficient and stable barite milling equipment has become critical for mineral processing enterprises. This article introduces barite milling technology, equipment selection, process layout and performance advantages to help you build a high-efficiency barite powder production line.
Barite features moderate hardness (3.0–3.5 on the Mohs scale) and low moisture absorption, making it highly suitable for dry grinding. The standard barite milling process includes crushing, grinding, classification, collection and packaging. Each step directly affects powder fineness, purity, output and stability.
First, raw barite must be crushed to a suitable feed size. Jaw crushers or hammer crushers are commonly used to reduce large lumps to less than 30mm, which helps improve grinding efficiency and reduce energy consumption.
The core stage of barite processing is grinding. At present, the mainstream industrial milling equipment includes Raymond mills, vertical mills, ultrafine vertical mills and European mills. For barite powder production between 80–400 mesh, the European mill and Raymond mill are the most cost-effective choices. For ultra-fine powder above 600 mesh, an LUM series ultrafine vertical mill is more suitable.


After grinding, the powder enters a high-efficiency classifier to separate qualified fine powder and coarse particles. Coarse powder returns to the mill for re-grinding, ensuring stable and uniform fineness. The finished powder is collected by a pulse dust collector, which guarantees high collection efficiency and environmental protection.
Barite milling has special requirements: high whiteness, low impurity content and stable fineness. Therefore, the mill must feature good sealing, low iron contamination and stable classification performance. Shanghai Shibang’s barite milling solutions adopt wear-resistant materials, optimized grinding chambers and high-efficiency classifiers to ensure high whiteness and high purity of finished powder.
In terms of energy saving, Shibang’s European mill and vertical mill reduce power consumption by 15–30% compared with traditional mills. The intelligent control system supports automatic operation, remote monitoring and fault warning, greatly reducing labor costs.
