MRN Pendulum Roller Grinding Mill

Working Principle

After hammer crushers (or jaw crushers) break large bulky materials to smaller ones, elevator works to send materials to material hopper. Then, by electromagnetic vibrating feeder, broken materials are evenly and quantitatively sent to the grinding chamber of MRN Pendulum Roller Grinding Mill. After grinding, materials are blown away by airflow to the powder concentrator for classifying. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure.
