Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers beneath a few …
Ball Mills vs Rod Mills. Previous. Next. When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the ...

In grinding, the SAG mills are used because of its capacity and short retention time for the processing of minerals and metals. SAG mills contain liners inside its structure. The liners crush the mineral and must be replaced each 6 months because they deteriorate during the crushing process. The measure of liners wears in SAG Mills requires a shut down …

AG/SAG is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media and this is the biggest difference compared with ball mill, through the mutual impact and grinding action to gradually reduce the material size.
Q1. What is a SAG mill used for? A SAG mill is used to grind and crush large pieces of rock into smaller pieces of rock, gravel, or dust. It is commonly used in the mining industry. Q2. How does a SAG mill work? A SAG mill uses a combination of impact and attrition to grind the material.
