Some questions during use cement vertical roller mill

1, the lack of feed When they find a lack of storage should stop feeding material, now lose out if continued risk free feed vertical roller mill, should feed vertical roller mill equipment and feed, or make the bed thinning attack rumbling sound, causing damage reducer . 2, the vertical roller mill is too large oscillations (1) feeding uneven, when the vertical roller mill mixes mostly powder, the load factor within the large vertical roller mill, resulting in thin material on the disc, and the disc with the roller directly touching, forming a vibration vertical roller mill; when the vertical roller mill when the mixture more for lump materials, formation pressure grinding roll is not stable, vibration grinding attack. The way to deal with the granularity of the grinding material is stable, appropriate adjustments grinding feed rate or reduce pressure, to ensure the required fineness of the material premise of proper lower separator speed. (2) fitting into the vertical roller mill, view the metal detector, the magnet separator is not working properly. (3) causing damage to the kiln exhaust fans or people shaking vertical roller mill kiln exhaust gas pressure is high, instability and dust concentration Ambassador vertical roller mill high temperature thereby increasing the vertical roller mill load moment should increase throttle opening of the cycle, increasing large recirculation flap into the vertical roller mill, increased vertical roller mill personnel a negative pressure, so that the vertical roller mill work balance.
