PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL OPTIMISATION - CASE STUDY V.K. Batra*, D. Bhaskara Rao** and Raju Goyal*** Holtec Consulting Private Ltd., New Delhi ABSTRACT Grinding technology has been continuously improving with numerous innovations with a view to improve productivity and reduce power consumption.
The EO system was first started up, together with ABB experts, at Adana Cement on 11 May 2009 for process optimisation of clinker production line 4, which has an average capacity of 4500 tpd, including the control of the rotary kiln, calciner and clinker cooler. In a second step the raw mill of line 4 and coal mill 2 were included in the EO system.
been made to optimize PID controllers of cement milling. The process simulation is combined with an autoregressive model of the errors between the actual process values and the computed ones. Long term industrial data have been used to determine the model parameters. The data include grinding of various cement types.
Cement Milling Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a … ball mill process parameters – Grinding Mill China
Cement mill is also called cement ball mill, which is mainly used for grinding cement clinker in the cement production process. It is one of the important cement equipment. The output of cement mill is 21~155 t/h, and the specific surface area of cement is 3300~3800 cm ² /g.
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
potential ability of the process engineers to control processing parameters to accomplish the desired cement fineness levels. In the second part of the study, a quantitative procedure for monitoring and evaluating cement milling process performance was described. Some control charts
