AI Technical Summary
Traditional vertical shaft impact crushers have a low single-pass yield, resulting in low production efficiency and requiring multiple crushing processes.
The design incorporates a spiral groove liner, an adjustable hammer position rotor structure, and a throwing disc. Combined with the tower-shaped distribution of the hammers and cylinder wall liner, it achieves step-by-step crushing and uniform impact of the ore.
It increased the single-pass pass rate to over 90%, significantly improving the crushing ratio and overall production efficiency.
