High-efficient cement manufacturing with POLYCOM® and SEPOL® PC – Machine and System Concept –

For cement grinding, the high-pressure grinding roll (HPGR) POLYCOM® and the static-dynamic separator SEPOL® PC can be installed as a finish-grinding circuit or, in combination with a ball mill, as a combi-grinding system.

1 Introduction:

The HPGR POLYCOM® from ThyssenKrupp Polysius has been successfully in operation for more than 25 years. More than 65 of the mills are producing high-grade cements in energy-efficient combi-grinding systems all around the world. The main characteristic of such a combi-grinding system is the pre-grinding of cement clinker in the POLYCOM®, which works in closed circuit with the static-dynamic separator SEPOL® PC, and after­wards finish grinding in a subsequent ball mill. One significant advantage of this system is the considerably lower specific power consumption compared to cement...
