The launch of SBM PMD New Generation Permanent Magnet Direct-drive Intelligent European Trapezium Mill marks a major breakthrough in grinding technology. For the first time, this model applies a permanent magnet direct-drive motor to pendulum mills, completely subverting the traditional transmission mode and realizing the deep integration of power system and intelligent control.
Permanent magnet direct-drive technology delivers stronger and more stable power output for grinding mills. Compared with traditional Raymond mills, the permanent magnet direct-drive European-version mill achieves a 30% increase in energy efficiency, leading to a substantial reduction in production and operating costs.
More stable power achieving a comprehensive energy saving rate of 15%.
Intelligent lubrication system enables non-stop operation.
Better sealing, high air flow speed, high powder selection efficiency and precision.
It provides warnings, ensuring stable operation and higher quality powder.
It improves aerodynamic efficiency by 15% and saves 8-10%6 of electricity.
An intelligent control system, it collects and analyzes data in real time.

Materials qualified after crushing are uniformly, quantitatively and continuously conveyed to the grinding chamber of the main unit by a variable-frequency belt feeder for grinding. The ground materials are driven by the air flow of the fan and conveyed to the classifier for particle size classification. Driven by the classification system, materials that fail to meet the fineness requirements fall back into the grinding chamber for regrinding, and finally discharged through the discharge mechanism as finished products.
It is suitable for grinding various non-flammable and non-explosive materials with a Mohs hardness below 7 and a water content of less than 6% in the fields of building materials, metallurgy, electric power, chemical industry, new energy, new materials, large and medium-sized non-metallic mineral powder making, limestone, calcite, dolomite, marble, gypsum, quicklime, heavy calcium carbonate powder making, environmentally friendly desulfurized limestone powder making, magnetic rare earth materials, bentonite, kaolin, bauxite, barite, clean coal powder preparation, petroleum coke powder making, etc.
