BrainWave SAG mill

BrainWave is ideally suited to stabilize the operation of SAG mills Effective grinding in a SAG mill depends largely on how it is loaded A mill containing too much material does not allow for adequate movement of the ore and balls A mill that does not contain enough material does not take advantage of the autogenous grinding mechanism...

Autogenous and Semi

Rely on our proven track record of SAG and AG Mill superiority Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills 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...

Grinding Circuit

A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al [6] is shown in Figure 96, where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced...

Grinding Mill

A Gupta, DS Yan, in Mineral Processing Design and Operation, 2006 661 Estimation of Operating Pressure To operate the HPGR Polycom grinding mill the pressure required is applied hydraulically through four cylinders to the roll that is designed to move laterally The second roll is immovable The crushing pressure applied is generally of the order of 200 MPa but for hard ores, higher ....

Outotec presents the world's largest SAG mill

Outotec has recently been awarded a contract to deliver one of the largest grinding mills in the world The contract includes the design and manufacture of a Ø40'x29' SAG mill The mill will be driven by a Gearless Motor Drive (GMD) which at 280MW is equal to the largest grinding mill power ever used in the mining industry...

Difference Between Sag Mill vs Ball Mill

Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding These mills utilize the balls in making the large fragments of materials broken into piec The ball charge of a SAG mill is about 9% to 20%This process takes place inside the large rotating drum of SAG mill which is filled with balls partially...

Grinding Mill Foundations

Sep 23, 2014· Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives)...
