high fineness mill

Efficient machine learning model to predict fineness, in a …

On the industrial scale, change in material grindability impacts significatively the mill performance in terms of material flow and product fineness. Indeed, a decrease in material grindability results in an increase on mill circulating load at same fineness level, and, therefore, mill material throughput drops down [44]. In other words, to ...
