Barite (barium sulfate) is a core raw material for oil and gas drilling mud weighting agents, paints and coatings, rubber and plastics, and barium salt chemicals. It requires high fineness, excellent whiteness, low iron content, and stable density. Traditional grinding mills are prone to contamination and produce inconsistent fineness, making it difficult to meet the requirements of oilfields and high-end chemical industries.
Shanghai Shibang has developed a complete range of equipment—including the LM Vertical Mill, MTW European Mill, LUM Ultrafine Vertical Mill, and SCM Ultrafine Powder Mill—specifically tailored to the physical properties of barite. These systems enable stable, clean, and efficient powder production, making Shanghai Shibang the preferred brand for barite deep-processing enterprises both domestically and internationally.
The core of barite grinding lies in low contamination, high classification precision, and stable density. The Shanghai Shibang LM Vertical Mill employs a bed grinding mechanism, resulting in minimal metal wear, controllable iron content, and high whiteness of the final product. It is suitable for large-scale production of 200–325 mesh drilling weighting agents, with an hourly output of 10–340 tons. The system operates under negative pressure to prevent dust leakage, and its integrated drying and grinding process simplifies operations.
For small to medium-scale production, the MTW European mill is recommended. Featuring thin-oil lubrication and smooth operation, its high-efficiency classifier ensures a high yield of 325 mesh material with uniform particle size, meeting the requirements of the paint and filler industries. It offers simple maintenance and moderate investment costs.
For the production of high-end coatings and ultrafine barium salts, the LUM ultrafine vertical mill is available. It produces finished products ranging from 325 to 2500 mesh with a concentrated particle size distribution, high purity, and low impurity levels. The specific surface area is controllable, making it suitable for high-end functional fillers. The equipment features a flip-up structure for easy maintenance, quick replacement of wear parts, and low long-term operating costs.
The SCM ultrafine mill offers higher efficiency and lower energy consumption for the same fineness, with a safe design free from the risk of loose screws, making it suitable for the production of high-purity barite micropowder.
Shanghai SBM’s barite production lines offer flexible configurations: the LM vertical mill for large-scale oilfield powder processing; the MTW European mill for small-to-medium-scale general powder processing; and the LUM/SCM for high-end ultrafine powder processing. Equipment wear parts are made of specialized wear-resistant materials to reduce iron contamination and ensure whiteness and purity; the entire process features intelligent control, simple operation, and stable performance, meeting environmental protection and safety standards.
With consistent quality and professional service, Shibang’s barite grinding solutions have been adopted in numerous mining and chemical projects both domestically and internationally, helping clients enhance product value and market competitiveness.
