IMPROVED CEMENT QUALITY AND GRINDING EFFICIENCY BY …

Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such

PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL …

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

) in the cement. The effect. of gypsum on the cement quality is critical and two-. fold. It affects two of the main properties of this. product, setting time and strength.1 For this reason. gypsum is added during cement grinding in the mill. feeding, requiring a weight feeder of high accuracy.

MODELLING OF CEMENT GRINDING

e ciency processes. The grinding of cement clin-ker from the kiln is the most ine cient process in the manufacturing, with an e ciency of 1 % (Benzer et al., 2001). This low e ciency makes optimization of cement clinker grinding circuits a task with large economical and environmental perspectives. Predictive control of cement processes inclu-

Vertical Grinding Mill Process Modeling

The required data for modeling of the grinding process have been taken from a recently commissioned cement plant that uses vertical roller mill for clinker grinding. In the vertical roller mill, clinker coming from rotary cement kiln is ground in the cement mill along with a small amount of gypsum and/or fly ash.
