Product Description
The MQR3254 roller mill is designed for medium-sized pellet production lines, offering high capacity and stable, reliable operation. It is an ideal choice for iron ore pelletizing processes.
Principle of Operation of the Polishing Mill: Raw materials (iron concentrate and bentonite) are fed into the rotating drum via a belt feeder at the feed end. Inside, the materials are subjected to impact from grinding media (steel balls), as well as attrition between the balls and between the balls and the drum liner. This process exposes fresh surfaces and ensures thorough mixing, increasing the -200 mesh content (feed size) by more than 10%. Finally, the processed material exits through the discharge port and proceeds to the next stage for pelletizing.
