A new approach for evaluating the performance of
The performance of the regrinding mill in the Sungun plant was evaluated through a detailed survey and it was quantified using a new proposed approach The approach was constructed based on the metallurgical objectives of a regrinding unit which are connected with the grindability and floatability of locked particles through the regrinding systemand the broader holistic approach to mill control are discussed also resulted in enhanced plant recovery as a result of a finer grind and a lower residue It is also evaluating the performance of various suppliers of advanced control systems If a particular mill mass setting creates poor mill performance, then a new mass Get Pricea new approach to evaluating the performance of The performance ratio of 58% was calculated for the Sungun regrinding mill Abstract This paper aims to develop a new approach for determining the performance of regrinding tumbling mills, which is based on the grindability and floatability of locked particles through regrinding systemsA new approach for evaluating the performance of
