An Intelligent Control System for Complex Grinding

2016-10-19  Grinding jobs are in the process of crushing the most important aspect of it is the crushing process continues, ore grade during the last pre-processing, classification in fact, in each of the ore with the ingredients separated from the current classification method magnetic separation, flotation and the like. The project grinding method using a ball mill, flotation and grading methods. Grinding operations associated with the great job grading, grading the quality of work indicators, it depends largely on the quality of ore grinding operations [5-6]. Grinding operations to comply with the required fineness grading operations, all the ore has a grinding fineness economy, • the fineness should be strictly controlled, appropriate grinding is often the key to effective implementation of dressing, grinding will be inadequate so that products are too thick, the degree of dissociation is not sufficient for economic separation, mineral recovery and enrichment rate is not higher than the mill is wasted valuable energy and mineral ground to a particle size less than the most effective method to sort out the required such cases are not allowed.
