Ball mill discharge end cap

This paper elaborates on the ball mill discharge end cover, a key component at the cylinder's discharge end that seals the cylinder, guides ground materials to discharge, prevents leakage of dust and media, and bears partial loads in collaboration with the hollow shaft. It requires strength and toughness, with Q235B and Q355B steel as common materials, featuring a flanged disc structure with a central stepped hole (for hollow shaft connection) and optional internal wear-resistant liners or grid plates.
