Vertical Roller Mill Operation
LM Series vertical mill is an advanced grinding machine, which integrated with drying, milling, grading and transporting. It is the high standard mill which can meet the high capacity of powder producing request.
LM vertical grinding mill is widely used in cement, powder station, metallurgy, chemical and non-metal industry. It adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, and elevator.
Especially, it can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.
operation and maintenance
- When the vertical roller mill working, you should observed the wind speed and input air, and they should not be too small.
- Good control of material layer. If the material layer is too thick or too thin, it will cause the vertical mill shock.
- The grinding materials can not have too large metal.
- Keep the vertical mill’s main motor electric current and pressure gate steady.

With the continual increasing demand for portland cement and constant pressure for reduced energy consumption, producers are exploring a wide variety of cost-saving manufacturing options. One option is vertical roller mill technology for finish grinding.
The single largest energy consumption point in the manufacture of portland cement is in the finish milling process. A reduction in power consumption here makes a dramatic impact on the plant’s overall power consumption. VRM technology makes significant power reductions possible by more efficient grinding.
Vertical roller mills create a particle size distribution with a sharper cut in comparison to cement milled in a traditional ball mill. That is, the particle size distribution is in a narrower band. This sharper cut means potentially less variability in product consistency and, hence, more predictable results in product performance.
By changing various vertical roller mill operating parameters, significant adjustments in the particle size distribution, retention time, and fineness of the finished cement can be achieved. This can help with plant operations as production is switched between different cement types.
