What is a SAG Mill? A SAG mill is a type of mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1.5 to 2.5 times the diameter of the shell. The SAG mill operates in a closed circuit with a screen. The product from the SAG mill is fed to a ball mill, which operates in a closed circuit with a cyclone.
WhatsApp: +86 18221755073SAG vs Ball Mills. By comesa_web Inglés. It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don't possess a single hardness. ...
