Before we cope with the FAQ in raymond mill operation,we should make clear about Raymond mill working principle. After the materials enter the grinding chamber of Raymond mill, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of Raymond mill main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. 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 Raymond mill work normally.The first raymond mill problem is powder Roller device abrasion,The reason is that Bearing out of oil, or sealing ring damage.Solution to raymond mill problem:refuel and clean the bearing device at the interval. The second problem is ground materials too coarse or too fine, Graet Wall company comments the reason is that over abrasion of analysis blade.the suggeation is to change analysis blade and turn down importing air volume to reduce coarse materials particles.
