SAG Mill Liner MaterialThere is no best sag mill liner material. Different working conditionals need different material to selection of the material of construction is a function of the appliion, abrasive of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
AG Mill and SAG MillThe working principle of the SAG mill and AG mill is basically the same as the ball mill machine, but the barrel diameter of the SAG mill and AG mill is larger. The raw ore enters the AG mill through the feeding inlet, and the material is brought to a high place under the rotation of the barrel and then falls.
