Difference Between Sag Mill vs Ball Mill - mech4study

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

They use ore exclusively as their grinding media but if the hardness and abrasiveness of the ore does not lend itself well to full AG milling, then a small charge of steel balls (6 to 15 % by mass) is added to assist in size reduction. This is known as a Semi-Autogeneous (SAG) mill. AG mills bring about size reduction by a combination of impact ...

AG Autogenous Grinding - Mineral Processing & Metallurgy

In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore. The main source of reduction comes from the impact of the rock falling on rock.

Autogenous and Semi-Autogenous Mills - ScienceDirect

Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media. Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills.
