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
Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use “grid” liners to form an autogenous liner surface.
Description of Semi Autogenous Mill(SAG Mill): This semi-autogenous mill, also called semi-autogenous grinding mill or SAG mill, is mainly used to grind ores and other particulate matter in different fields, like chemical industry, mining field, metallurgy industry, building material sector, and so on.

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.

Our robust autogenous and semi-autogenous mills ensure efficient self-comminution of the product within the mill. In many cases, a SAM mill can replace a high-maintenance combination of crushing and screening equipment, making it a reliable, cost-effective alternative. As with ball mills, the material inside is lifted by the rotary motion
Autogenous Mills. Semiautogenous Mills. By Application: Metal Mining. Non-Metal Mining. Regional Analysis: The report offers in-depth assessment of the growth and other aspects of the Autogenous and Semiautogenous Mills market in important countries (regions), including: North America (United States, Canada and Mexico)
The data show that, although an ideal product was never obtained, the screen undersize products approached the desired size limits (88 percent minus 325 mesh). The cursory study indicated that autogenous grinding of mica in the attrition mill is technically feasible, but additional research would be required to optimize operating conditions.
Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore. Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media. The grinding is facilitated in autogenous mills by attrition
Autogenous milling means a pr ocess i n which the size of the constituent pieces of a sup ply. of rock is reduced in a tumbling mill purely b y the inte raction of the pieces, or by the
Answer (1 of 3): Question
An autogenous mill of ID 6.7 m and an effective grinding length of 2.1 m was fed with ore of SG 3.8 to 20% of its volume. The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speed. The solids in the mill charge were at 80% solids. Estimate: 1.
Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
The end cover of the autogenous mill is made of steel plate and welded into one body; the structure is simple, but the rigidity and strength are low; the liner of the autogenous mill is made of high manganese steel. The end cover and the hollow shaft can be made into an integral or split type according to the actual situation of the project.
Fully autogenous mills rely on the large, competent fraction of feed to act as grinding media. Research indicated that Hibtac mills require specific amounts of 6 to 10-inch ore. High recirculating loads require a steady influx of large rock. Blast designs, therefore, are presently characterized by wide patterns and low powder factors.
Semi-autogenous grinding mills. Semi-autogenous Metso Outotec SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening.

Pilot plant testing for primary autogenous or semi-autogenous grinding gives the following information needed for selection of mills, circuit design, and mill design. (1), (2) and (3). Since the ore determines the nature of the product from an autogenous or semi-autogenous grinding circuit, the first thing to be determined is the suitability of
