Autogenous and Semi-Autogenous Mills FLSmidth

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill designs in order to provide the most robust, safe, and efficient grinding mills

What’s the difference of Ball mill, SAG mill, AG mill?

A Sag mill is most often used in the mining fields, particularly in the mining of precious metals such as gold, copper, silver, and nickel. The sag mill serves in the line of industrial mining equipment designed to process, crush, separate, or locate precious metals from mined coal. The Sag mill is one of the large mining equipment pieces, and often requires mining equipment repair and maintenance. This is

Autogenous and Semi-Autogenous Mills ScienceDirect

01/01/2016· The disintegration and size reduction of ores in AG/SAG mills is brought about by a combination of impact, attrition and abrasion forces during mill rotation. Particles at the toe of the mill charge receive the maximum impact forces from falling rocks and other grinding media. Particles in the body of the mill charge partly slide from different heights and are subjected to attrition and abrasion

Dept. prior to Feb. 29, 2008. Copyright 2007, Society for Mining, Metallurgy, and Exploration, Inc. Introduction Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions

Choosing vibration monitoring methods Applications

A SAG mill is generally used as a primary or first-stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles.SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. These mills are characterized by their large diameter and short length, as compared to

AMIT 135: Lesson 6 Grinding Circuit Mining Mill

AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill red=fastest, blue=slowest moving particles [image: (135-6-4)] The mill product can either be finished size ready for processing, or an intermediate size ready for

Optimizing your SAG mill operation International Mining

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at

Difference Between Sag Mill vs Ball Mill mech4study

12/10/2017· SAG mills are very important equipment of industrial mining. SAG mills are commonly used in mining fields. From mined coal, it separates out some precious metals. In the mining, some precious metals found are like gold, silver, nickel, and copper etc. Ball Mills: Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small

Attrition mill operating characteristics ScienceDirect

01/07/1975· The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively. Size reduction rates for relatively coarse
