SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the …

Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...

Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2), which renders to the AG/SAG mill the credit for the fraction of the material that had been already ground to final product (Q1). To calculate the operating work indices,

The material will pass through the concentration process where it will be grinded, using ball and autogenous mills and will undergo gangue separation. The material will then undergo magnetic separation, dewatering, screening, hydro separation, and flotation to produce blast furnace (BF) and direct reduction (DR) grade concentrate. The BF ...

Abrasion is the main mechanism of comminution in autogenous mill, while impact crushing predominates in ball mills (Digre, 1979). Although the simulation of autogenous and ball mills is difficult in batch laboratory conditions, the charge, which is the ore itself in autogenous mills, also causes abrasion rather than impact action.

An autogenous (AG) mill is a grinding mill used in the minerals processing industry. It is shaped like a huge drum on its side and spins rapidly to carry ore to the top using centrifugal force. Gravity assists in smashing ore against other ore to pulverise rock to a size small enough to seperate minerals from gange.
