Steel balls as traditional grinding media are prone to excessive fines generation and high energy consumption. Therefore, in light of this problem, the authors investigated another media—ceramic balls based on the output characteristics of fine particles. This study discusses the effect of ceramic balls on the change of the particle size distribution, zeroorder output characteristics, micro ...

This implementation realises the concept of combining HPGR and tower mill in a comminution flowsheet. A flipflow screen, based on the trampoline effect (alternate "stretch and relax") and acceleration on meshes of up to 50G (Skako, 2021, Chen et al., 2021), is used in the HPGRclosed circuit to screen ore down to −1 mm, which is beneficial for treating fine, damp and low density ...
