Grinding and classification performance evaluation and modelling of an industrial-scale horizontal roller mill process
Grinding and classification performance of an industrial scale Horomill grinding and classification closed circuit was evaluated. Perfect mixing modelling approach was implemented to model Horomill process. Classification performance of the high efficiency dynamic TSV air separator was evaluated by using efficiency curve approach .
Cement is conventionally produced in multi-compartment type ball mills which is a energy intensive process . Typical energy consumption of the grinding stage of cement production is about 40 kWh/t in a cement plant [4, 5]. In this respect, grinding technologies such as vertical roller mills, high pressure grinding roll crushers (HPGR) and the Horomill are used in finish grinding of cement in cement plants in the recent years as they are known to be energy efficient systems. Grinding is achieved by high compression in these systems. The energy efficiency of these systems was...
