However, a vertical roller mill for cement grinding generally requires the use of grinding aid to achieve the most efficient operation with a stable grinding bed and a low level of vibrations. Vertical roller mills grinding an OPC of low fineness, say around 3000 cm2/g (Blaine) can operate without grinding aid, but even when grinding to that ...
The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall. The transition zone consists of 50 mm and 60 mm balls. The basis is a 50 mm ball size for 5% residue on the 4 mm sieve.
The mill incorporates all the mechanisms based on practical grinding theory to ensure high-efficiency such as optimally contoured rollers and matching grinding track section, ensuring grinding to ...
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
