Research on the Major Measures to Reduce Overgrinding
Overgrinding,which increases energy consumption and deteriorates subsequent beneficiation processes causing a waste of mineral resources,is ubiquitous in the whole process of both crushing and grinding.Optimization in grinding medium and classification system produce remarkable results to reduce overgrinding.New grinding media such as ceramic ball can provide bettergrinding effects than traditional steel ball;advanced system of classification can refrain from unwanted grinding.Mainly based on practical production,this paper discusses how the improvementsin aspects mentioned above reduce overgrinding andenhance technical-economic index.
