On this month's cover: COMFLEX, KHD´s new grinding system, is a modular, compact and multi-talented grinding solution for the cement and minerals industries. COMFLEX is used for finish and semi-finish grinding of raw materials, cement and slag. This new grinding system combines well-proven KHD technologies: roller press with swing frame for easy and fast roller change and a tailor-made separating unit, taking care of separating, drying and conveying. The system enables production rates of more than 1000 tph raw meal and 600 tph cement to fit large kilns with single grinding units. COMFLEX features high flexibility for a wide range of applications and product qualities, lowest energy demand and favourable particle size distributions. Contrary to other grinding systems, with COMFLEX at least 50% of the grinding capacity is available during maintenance of grinding tools.
