However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.
ASTM C 125 defines the maximum aggregate size in one of two ways: Maximum size. The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]). Nominal maximum size. The largest sieve …

2 BALL MILLS INTERNATIONAL CEMENT REVIEW FEBRUARY 2021 aim of delivering a target mill discharge size at the end of the chamber, with a maximum residue of five per cent >2mm. This is a standard limit and is practically known to guarantee the coarsest grain to be <6mm – a standard discharge slot size of an intermediate diaphragm. In this
The biggest ball size is calculated by the Bond formula and depends mainly from feed size and mill dynamics. (See also "BP Selecting Shell Liners in ball mills" to avoid 100mm balls). Most common is the 90 mm ball as biggest size but even 80 mm is possible depending on the clinker size.
