Dynamic Classifier For Coal Mill
Product Description
Coal preparation is high-risk and high-demand. Our MD series Dynamic Classifier is built specifically for this environment. Integrating vortex, inertia, and centrifugal grading, it ensures coal powder is separated to the micron level required for boiler combustion. Operating under negative pressure, it works seamlessly with air-swept coal mills, simplifying the system and saving over 10% in energy compared to standard models.
Safety is paramount. Every MD unit features an explosion-proof shell and pressure relief vents. For a decade, our MD850A model has maintained an outstanding record of coal powder fineness (80μ residue < 2%) for power plants.
