Effect of Grinding Aids in Cement Grinding

In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to obtain the product, but it is usually more expensive, requires more energy and reduces capacity.

Consumption of steel grinding media in mills – A review

One obvious reason is that impact energies in laboratory mills are negligible compared to those in industrial mills. For example, Dodd et al. (1985) have estimated that an increase in ball kinetic energy from 1.4 J for a 0.025 m ball in a 0.20 m ball mill to 350 J for a 0.127 m ball in an 8.5 m ball mill.
