Improvements by 2-stage separation
One of the most efficient cement grinding technologies is an HPGR operating in semi-finish grinding mode. Compared to a closed circuit ball mill grinding circuit with a dynamic air classifier, specific energy consumption is reduced by approximately 30 %.
The Köppern 2-Stage Koesep is a combined separator comprising two separation stages in one compact housing. It is specially developed for HPGR applications operating in semi-finish or finish grinding mode. Due to its compact design the 2-Stage Koesep is well suited to upgrade existing grinding plants.
Using the 2-Stage Koesep, only one compact separator is necessary to operate an HPGR in semi-finish grinding mode. Grinding circuits with the 2-Stage Koesep offer numerous advantages compared to equivalent combined air separation systems, such as:
