Raw Grinding Ball Mill Feed Size And Capacity. Ball mills are customarily divided into categories that are mainly defined by the size of the feed particles and the type of grinding media intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 15 times the shell diameter.
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
