2020-10-20  When the grinding time exceeded 25 min, the gradation change of the AFF was generally much smaller. Fig. 10 b shows the 60-minutes-dissolving conductivity of the AFF against the grinding time. Firstly, the dissolution of the deicing chemical decreased with the grinding time increased, and then the conductivity curve went up when the grinding time passed the 25 min.

2020-4-7  Abstract: The entrainment of fine particles in underflow of a grinding-classification hydrocyclone can cause ore overgrinding, which will lead to reductions in both metal recovery and ball mill throughput. To address this problem, this paper proposed a W-shaped hydrocyclone that can e ectively reduce underflow fine particle entrainment.
