Cement production raw meal production in steps perfectly mixed, accurately fed without pulsation, and precisely weighed.The key word is quality and this quality is achieved during cement production with exactly matched process steps.In the first stage, the raw meal is produced, as described below.
Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout, as well as tramp metal detectors to protect equipment and keep the operation running smoothly.The cement manufacturing process flow chart sums up where in the process each type of technology is making a difference.Note.
This is achieved in a cement raw mill.The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15 by mass consists of particles below 5 m diameter, and 5 of particles above 45 m.The measure of fineness usually used is the specific surface area, which is the total particle surface area.
