separator speed significance in cement mill

Next chapter in the FL OK™ mill legacy

Product quality is a function of cement particle size distribution (PSD) and the dehydration of the gypsum within the cement. In the OK mill, parameters, such as mill air flow, separator speed and grinding pressure, can be easily adjusted during operation to control or alter the PSD curve to a profile (steeper or flatter) that achieves the ...

INVESTIGATION ABOUT THE EFFECT OF CHEMICAL GRINDING …

- Increase in separator speed: higher circulating load is obtained by increasing the mass of material in the reject stream. This allows to modify the cement particle size distribution, thus obtaining a finer and better performing cement. Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding

Advanced process control for the cement industry

grinding plant, separator speed and fresh feed are the main control parameters. The MPC controller frequently calculates new set points for the two parameters. The calculation is based on minimizing a so called "cost-function" meaning minimum deviation from production targets and minimum changes of separator speed and fresh feed.
