Small-to-medium-sized non-metallic mineral powder processing plants commonly face challenges such as limited budgets, cramped spaces, and a shortage of operations and maintenance personnel. Traditional, outdated Raymond mills are energy-intensive, prone to coarse particle leakage, and suffer from frequent bearing failures, making it difficult to meet environmental protection and stable production requirements. The MTW Series European-Style Grinding Mill, developed by SBM, incorporates mature European grinding technology and has been iteratively optimized based on feedback from over 10,000 customers, making it the primary equipment for standardized powder production of materials such as limestone, gypsum, bentonite, and marble.

The core advantages of the MTW European Trapezium Grinding Mill lie in four major structural upgrades. First, the innovative curved scraper blades expand the material grinding contact area, increasing output by more than 15% for the same main unit specifications, and are suitable for the mass production of desulfurization limestone and construction gypsum powder in the 200–325 mesh range; second, the drag-free spiral air inlet design ensures smooth airflow and reduces air resistance losses, lowering the machine’s overall energy consumption by approximately 10% compared to traditional grinding mills; Third, a full-machine thin-oil lubrication transmission system replaces the outdated grease lubrication, resulting in lower bearing operating temperatures, doubling service life, and reducing the frequency of downtime for maintenance; fourth, a built-in cage-type high-efficiency classifier ensures high classification accuracy, effectively preventing coarse particles from mixing into the finished product, and delivering uniform and stable particle size that meets standards for building materials and chemical fillers.
The equipment accepts feed material up to 50 mm in size, with a finished product fineness range of 0.038–1.6 mm, covering the mainstream powder requirements of 80–400 mesh. Models range from MTW115G to MTW218G, with individual unit capacities of 3–45 metric tons per hour, suitable for projects with annual production capacities of 100,000–400,000 metric tons of powder. The entire system operates under negative pressure in a sealed environment and is equipped with a pulse-jet baghouse dust collector. Dust emissions comply with domestic environmental protection standards, eliminating the need for additional large-scale dust collection facilities.
To accommodate different material characteristics, Shibang can integrate electromagnetic vibrating feeders, elevators, and storage silos to form a fully integrated production line. This allows for the processing of gypsum filter cakes with a moisture content of up to 8% and raw limestone from open-pit mines without the need for a preliminary drying process, thereby simplifying the production workflow. Multiple operational production lines—including those for Inner Mongolia bentonite, Shanxi limestone, and Hubei silica—utilize the MTW European Trapezium Grinding Mill. These mills feature low failure rates during long-term operation and extended replacement cycles for wear parts, significantly reducing customers’ operating costs.

Many first-time plant builders are unable to determine which machine model is suitable for their specific materials; blind purchasing often leads to issues such as insufficient production capacity and failure to meet fineness standards.
