LM190 vertical roller mill is a completely new and innovative design and a further step to more efficient grinding of soft and medium-hard products. The basic concept is based on a combination of the lower section of the mill featuring the roller and its supports, the grinding table and drive system, together with a series of highly efficient classifiers.
Operation and maintenance of vertical roller mill
1. When the vertical roller mill working, you should observed the wind speed and input air, and they should not be too small.
2. Good control of material layer. If the material layer is too thick or too thin, it will cause the vertical mill shock.
3. The grinding materials can not have too large metal.
4. Keep the vertical mill’s main motor electric current and pressure gate steady.
