Horizontal roller mill (Horomill®) application versus hybrid HPGR/ball milling in finish grinding of cement

Industrial scale Horomill (R) and hybrid HPGR/two-compartment ball mill applications at puzzolanic portland cement production were presented with emphasis on the general operational characteristics of the circuit configurations, size reduction and energy efficiencies of the Horomill (R) and two-compartment ball mill grinding conditions. Horomill (R) circuit configuration indicated to have advantages in terms of production of high strength cement as compared to Hybrid HPGR/two-compartment ball milling, depending on the classification performance of the separators influencing the circuit performance.
