Sag Mill Vs Ball Mill
What is the Difference Between SAG and AG Mill?
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.
