## Wet Semi-Autogenous Grinding Mills

Wet Semi-Autogenous Grinding Mills. Previous Next View Larger Image; The primary mill liner task force was formed in 1977. Its function was to improve the operating costs and milling efficiencies of the ten 8.2-m x 5.5-m (27 ft x 18 ft) wet SAG mills that were operating at the time. The SAG mills are driven by two 3500 HP motors drawing a total of 5450 kW at 76% of critical speed. In MarchSemi-Autogenous Grinding of Copper Ores,As in the case of autogenous grinding, the comminution process occurring in a SAG mill is also a combination of impact and abrasion. Operating conditions, which favor abrasion, for instance low loading of small size balls, may lead to high wear of balls and liners and result in operational problems due to the buildup of coarse material in the mill and the grinding of the feed to extra fine

case it is called semi-autogenous (SAG) grinding. Conceptually, any AG/SAG mill consists of a rotary cylindrical metallic chamber in which the feed is con-tinuously introduced through the hollow feed trun-nion at one end and discharged to another. The discharge mode does vary substantially between hol-low discharge trunnions to screen plates (grates) that can be either placed at the peripherySemi-Autogenous Grinding (SAG) mill DEM ,03/09/2019· Grinding simulation of ore particles in a Semi-Autogenous Grinding (SAG) mill to optimize grinding efficency, reduce wear or evaluate design changes.

## A Method of C alculating Autogenous/ Semi-Autogenous

griding/semi-autogenous grinding (AG/SAG), mill speci c energy is now calculated by various ﬁ empirical formulae and pilot testing carried out in small laboratory mills. Barratt (1989) described a method using Bond Indices than adding a single factor of 1.25 to arrive at the AG/SAG speciﬁ c energy. In 1991 the Canadians developed the SAGPower Index (SPI), test using 2 kg of material in aSemi-Autogenous Grinding of Copper Ores,As in the case of autogenous grinding, the comminution process occurring in a SAG mill is also a combination of impact and abrasion.

## What is SAG Semi-AutoGenous Grinding and

Semi-autogenous grinding is used in place of autogenous grinding when the ore does not produce the necessary competent media. Forged steel balls are used to supplement the coarse ore. In the past, the same ill geometry has been used as in autogenous mills with modifications in the structural design to account for the increased weight of media and pulp loading. (Because supplementary ballSAG Mill Semi-Autogenous Grinding Mill,SAG Mill Semi-Autogenous Grinding Mill A SAG mill is characterized by its large diameter and short length.
