Increasing emphasis on productivity and quality control has provided an impetus to research on better methodologies for diagnosis, modelling, monitoring, control and optimisation of mineral process systems. One of the biggest challenges facing the research community is the processing of raw sensor data into meaningful information.
Jun 08, 2016 Points of Control. The crushing plant is the first point at which control must be exercised. Almost without exception, fine crushers are operated in closed circuit with screens so that a positive size of feed is maintained at all times. The second point of control, and one of the most important, is in the mill storage bin.
