The ring granulator is primarily utilized in coal-fired power plants, mining, and other industries for the primary and secondary crushing of coal and other materials with medium to low hardness. Its crushing principle involves a high-speed rotating rotor driving hammer heads to impact material, and squeezing the material between the hammer heads and the concave and screen plates. From this perspective, the hammerheads necessitate high reliability and consistency to ensure the dynamic balance of the rotor at high speeds. Furthermore, in practical applications, they must possess balanced mechanical properties such as strength, ductility, toughness, and hardness to withstand materials changes in the feed and different degrees of impact, thus achieving superior reliability and wear resistance.
