Vertical Roller Mills (vrms) are equipment with the following characteristics. A rotating, circular grinding table that turns around a vertical shaft. Mills are used to grind fuel (FCB mill E type) and Raw meal New on cement.Preparation of cement raw materials. Alite (approximately Ca 3 SiO 5) provides almost all the early strength (strength up to seven days of curing) of cement and a moderate amount of late ( 7 days) strength. Belite (approximately Ca 2 SiO 4) provides very little early strength and a large amount of late strength.So it can be seen that these small compositional changes have a.
The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill’s modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills regardless of size and application.Raw meal grinding is a key part of the raw material preparation process. Varies types of cement raw mills are the main helper in this stage. The amount of each material received by the raw mill depends on the speed of belt conveyors which take the materials from their respective storage bin and feed them into the raw mill.
Raw meal, Hot meal and Clinker Parameters Lime Saturation Factor (LSF) is the ratio of the actual amount of lime in raw meal clinker to the theoretical lime required by the major oxides (SiO 2, Al 2 O 3 and Fe 2 O 3) in the raw mix or clinker.
