Vertical roller mill optimisation

Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill.

Cement Manufacturing Process: What is Cement made of.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.Cement Manufacturing Process, Cement Bricks Factory,We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thousandth of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength.Cement mills and raw mills for small to medium throughput,MVR vertical roller mill with planetary gearbox . the material is conveyed to a stationary nozzle ring due to the rotation of the grinding table. Gases (air or hot gas) flow through this nozzle ring, take up the ground and dried material and convey it to the classifier where it is separated by the rotating wheel (rotor) into grits and fines
