3 Roller Raymond Powder Mill for Limestone

Raw material requirements: noninflammable and non explosive materials;  Mohs hardness ≤7, moisture ≤6%; Charge size

requirements: 5-25mm; Final product size80-325 meshes, some products can reach to 600 meshes .

After the materials enter the grinding room of the main equipment, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roller rolls.

After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding room for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust catcher.
