  Energy-Efficient Comminution: Best Practices and Future

  2017112 · The weakening results in lower grinding energy and breakage is reported to be preferential along grain boundaries enhancing liberation for improved mineral separation. In open-pit mines, improvements in mill performance have been achieved by increasing the energy intensity of blast patterns, thereby reducing the size of feed to the mill.

  Improved extraction of alumina from coal gangue by surface …

  2016111 · In order to elucidate the mechanisms of the improved alumina dissolution by grinding, changes in physical properties of coal gangue samples were monitored after grinding. Volume mean diameter (D 4,3 ) and the median particle size (d 50 ) decreased but the span values ((d 90 − d 10 ) / d 50 ) increased with the grinding time prolonging ( Table ...

  Multi-objective optimization of planetary roller screw

  202191 · In this paper, the mathematical model of PRSM is established to obtain the load distribution of planetary roller screw mechanism (PRSM) in different installation modes considering pitch errors and pitch deviation. An improved iterative algorithm is proposed to solve the calculation un-convergence caused by unloaded thread.
