· Fast wear and short service life of pump body caused by high-abrasion ore slurry

· Easy clogging of flow path by large-particle ore slag

· Difficult underwater discharge of tailings pond and insufficient suction head

· Unstable transportation of high-pressure and high-concentration slurry at ball mill outlet

· Air entrainment, insufficient flow and low efficiency of flotation foam slurry

· Complex equipment maintenance and production impact from downtime
