power consumption equation of vertical roller mill


In normal operation of the vertical mill, the vibration value of the mill should be strictly controlled within a reasonable range, and no more than 0.9mm/s should be allowed in an instant. 6. Air volume control The power consumption of products is closely related to mill output. The higher the output, the lower the unit power consumption.

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power ...

Best energy consumption - International Cement Review

Figure 3: vertical roller mill. ... The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent. Manufacturers have countered this generally satisfactorily with pressure drops reduced by lower nozzle ...

Vertical roller mill for cement grinding

The advantage of the vertical roller mill for cement (comparison with the tube mill) 1) Highly efficient grinding is possible with considerably low electrical power consumption. 2) The residence time of cement grinding in the vertical roller mill is much shorter than that of tube mill. Since system operational control response is superior,

Modern Processing Techniques to minimize cost in Cement Industry

The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton.
