Cement Production - an overview | ScienceDirect Topics
A cement raw-mix blending application and a cement mill grinding MPC application. In applications, we apply a linear model predictive control (LMPC) algorithm with soft constraints. The proposed LMPC in both applications is able to optimally control the system operation, reduce power consumption, and improve production.

Clinkerization - Cement Plant Optimization
When coal is used as fuel, the ash content and its composition should be considered in raw mix design. LSF of clinker lies in the range of 92-98. Higher LSF at controlled free lime content translates to better quality of clinker (high C3S), difficult clinkerization, high heat consumption.

11.6 Portland Cement Manufacturing
The dry raw mix is pneumatically blended and stored in specially constructed silos until it is fed to the pyroprocessing system. In the wet process, water is added to the raw mill during the grinding of the raw materials in ball or tube mills, thereby producing a pumpable slurry, or slip, of approximately 65 percent solids.
