To ensure profitable operations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of lowgrade deposits become necessary. More powerful and larger mills, higher ball charges and demanding ambient conditions call for a strong partner for grinding solutions.
The mill at Orissa Cement was guaranteed to produce 212 tonnes per hour of PSC at 3800 cm2/gm Blaine without the use of grinding aid and with a mill area power consumption of kWh/tonne. However, as shown in table 1, its operational performance has exceeded this guarantee.
The operators and process engineers must be able to evaluate all the process variables in order to optimise the mill system production. The grinding technology and mill operations course provides the necessary knowledge to maximise the production rate and promote operational stability while ensuring the grinding systems operate efficiently.
