SED-500CFS1-H — Integrated Ultra-Fine Pulverizer

Material is conveyed into the grinding chamber (between the machine body and guide ring) via a screw feeder. High-speed rotating blades strike the material against the fixed toothed ring, causing impact, shearing, and inter-particle/blade/ring friction for alternate grinding. Crushed fine particles, driven by negative-pressure airflow, rise over the guide ring into the classification chamber. The high-speed classifier wheel generates centrifugal force opposing the negative pressure: particles larger than the critical diameter are returned to the grinding chamber; particles smaller than the critical diameter pass through the discharge pipe to the cyclone collector and exit via rotary valves. Classifier rotor speed (variable) is the key control for product fineness.
