The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R 0

Abstract The influence of the operating frequency the milling ball and grinding stock filling degree the material of the milling balls and beakers the milling ball diameter and the size of the milling beakers on the temperature increase inside the milling beakers in a mixer ball mill was investigated

SAG mill balls experience both significant abrasive and impact wear due to their large (75 – 100 mm) diameters Ball mill balls experience a greater number of impacts but at lower magnitude than SAG mill balls due to the smaller ball size and smaller mill diameter Feeds are typically highly abrasive

1-6-2005There are many other solutions however if the efficiency of a SAG mill is not what you are after all of the other options cost more in terms of maintenance and materials (eg pure ball mills hammer mills and rod mills) AG and SAG mills are cheap to operate and some inefficiency is

RoM Ball mills – a comparison with AG/SAG Milling Aubrey N Mainza1 and Malcolm S Powell 1 1Mineral Processing Research Unit University of Cape Town Rondebosch 7700 South Africa amainzaeng uct ac za ABSTRACT SAG mills are distinguished by utilising run-of-mine (RoM) feed as

length(m)) following two parallel ball mills (5dia (m)*7lenght(m)) The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method Miduk SAG Mill circuit is shown in Figure 1 Figure 1 Diagram of Miduk Copper Complex SAG Mill

Advances in Discrete Element Method Application to Grinding Mills 119 to 2D non-spherical to 3D slice to 3D full (Cleary et al 2003) the prediction of shoul-der angle toe angle power and vortex cen-ter increasingly improved Obviously these findings point in the direction of 3D DEM for full scale charge motion plus breakage studies

difference in the P80 and a 1% difference in the %75m and the particle size tendencies are correct (the finest feed gives the finest discharge) LUX J and CLERMONT B The influence of mill speed and pulp density on the grinding efficiency for secondary stage grinding International Platinum

SAG mills are essentially autogenous mills but utilize grinding balls in addition to large rocks to aid in grinding A SAG mill is generally used as a primary or first stage grinding solution SAG mills are used at gold copper and platinum mines with applications also in

While AG mills operate without a ball charge SAG mills use a grinding media charge of normally 3 % - 12 % for comminuting the feed material The maximum feed size is between 200 mm and 500 mm The AG/SAG mill is normally installed upstream of a tube mill operating in closed circuit with hydrocyclones

The designs of autogenous and semi-autogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills Methods of estimating SAG mill volumes mill charges feed size and power consumptions and optimum speeds of rotation during operation are described

Allow me to compare Ball mills can be of the overflow or of the grate discharge type Overflow discharge mills are used when a product with high specific surface is wanted without any respect to the particle size distribution curve Overflow discharge mills give a final product in an open circuit

CONGA THE WORLD'S FIRST 42 FOOT DIAMETER 28 MW GEARLESS SAG MILL ABSTRACT In 2010 Newmont made the decision to purchase a 42 foot (ft) Semi-Autogenous Grinding (SAG) mill from and a 28 Mega-Watt (MW) Gearless Mill Drive (GMD) from ABB for the Conga Project in Peru

The operating cost difference between the two circuits is driven by the difference in ball mill steel wear between the SAG/ball mill circuit and the crushing/HPGR/ball FL – FL breaks world record in Chile Before the Esperanza order FL's largest SAG mill measured 38' and its ball mills 26'

Enter the number of lifters that are exposed above the mill charge Fractions are acceptable and should be used in the case where the charge does not sit uniformly in the mill For example you may have 29 rows exposed at the discharge end of the mill and only 28 exposed at the feed end

11-1-2011On the S width method small direct measurement differences cause big variations on the charge level estimatives and the trend of such errors is to increase in smaller diameter mills which is the case of the measured ball mill The MCP eliminates vague criterias adopted by people while measuring mill internally by common methods
