There is no best sag mill liner material. Different working conditionals need different material to selection of the material of construction is a function of the appliion, abrasive of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, VERTIMILL® or a stirred media detritor (SMD). Grinding circuit design AG/SAG mills are normally used to grind runoffmine ore or primary crusher product. Feed size to the mill is ...

4 The SAG mill model in the JKSimMet software has not been shown to accurately reproduce the performance of a single stage mill for greenfield design. A review of most modern power models shows that the prediction of specific energy is influenced by the high energy breakage characteristics of the ore (DWi, t 10, SPI etc.) and the low energy (BWi).

The collected SAG feed sample was prepared for pilotscale HPGR and stirred mill testing to determine the key operating parameters for flowsheet design and powerbased calculations. Ultimately, the simulation and test results allowed for the direct comparison of the energy and costs for three circuits.

Oct 05, 2010 · Metso has been selected to design and supply a 42ft x 25ft, ( x ) 28MW gearless SAG mill, plus two 26ft x 42ft, ( x ) ball mills and two VTM1500WB VERTIMILLS® for Newmont Mining's Yanacocha Conga coppergold project in Peru. The 42ft diameter SAG mill is the world's largest and the first of its kind.

Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter ( Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

4 x SAG mills (40foot diameter, 28 MW) 5 x ball mills (26foot diameter, / 22 MW) 4 x 800 tph tertiary cone crushers. Over the past year, Lycopodium has been completing the process plant design and the services to nonprocess infrastructure buildings and, as of .

The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits recirculation of pulp back into the mill.

Grinding mills are used to break solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. If you would like to speak with us about Grinding Mills please Call Us at our Mining and Operations office. The grinding of solid matters occurs under exposure of mechanical forces.

Jun 01, 2005 · SAG mills are often used as regrinding mills after a fully autogenous milling. Thus giving them a lower efficiency as they are grinding very small rocks to start with. ...

FEA simulations make it possible to reproduce the mechanical behavior of both liners and the mill under various operating conditions in order to ...

Mill drive arrangement. Mill drives are generally loed on the outside of the mill to facilitate maintenance. • Mill discharge arrangement. If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, .

Aug 25, 2014 · So perhaps we should not evaluate SAG mills in the traditional configuration of perhaps a +/12% ball charge and a <20% total charge in a high aspect shell design. Yanacocha for example, has a 19% ball charge and a 21% total charge Newmont has explored every other possibility with the final result of staying with this loading as it is the ...
