[0002] Wet grate autogenous grinding mills are used to grind ores and other materials of varying hardness. They are widely used as the primary equipment for grinding operations in non-ferrous and ferrous metal beneficiation, the chemical industry, and the building materials industry. A low-speed synchronous motor directly drives the rotary section through a large peripheral gear reduction transmission. The cylinder is filled with appropriate grinding media—steel balls. Under the action of centrifugal force or friction, the grinding media is lifted to a certain height and falls in a tossing or cascading manner. The material to be ground continuously enters the cylinder through the feed port and is crushed by the moving grinding media. Qualified products are then forcibly discharged from the machine through the grate liner and the built-in cylindrical screen for the next processing step.

[0007] Through the above technical solution, qualified and unqualified products can be quickly separated, and the two products can be discharged separately to maintain effective transportation.

[0008] Furthermore, the flange is designed to be matched with the discharge lining flange of the autogenous grinding mill, and a plurality of fastening bolts are evenly installed on the inner wall of the mounting opening of the top wall of the flange.
