Vertical Shaft Kiln Structures & Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer. Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.
This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying (G-NLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints. Different objective functions are …
