The operating cost difference between the two circuits is driven by the difference in ball mill steel wear between the SAGball mill circuit and the crushingHPGRball FL FL breaks world record in Chile. Before the Esperana order FLs largest SAG mill measured 38 and its ball mills 26
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
The 2.0 MW semi-autogenous grinding SAG mill and 3.7 MW ball mill were assisted by a crusher and a 3.7 MW ball mill in closed-circuit with 400 mm. Get Price Plant performance improvements

SAG Mill power of sag mill. 3. Select SAG power at a minimum of theth percentile of hardness variability unless other considerations make another choice more reasonable.. One such consideration is the decision to use a pebble crusher in the SAG mill circuit. This adds grinding capability to the SAG mill and allows the selection of a smaller
2009-8-26The ROM SAG mill circuita brief description The typical ROM SAG mill circuit is depicted in Figure 1. The circuit is usually closed with either a screen or more commonly a cyclone for product sie classification. The focus of control can be divided into two parts vi. the mill and the cyclone. The importance of cyclone performance should
AGSAG mills can accomplish the same sie reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill. Because of the range of mill sies available AGSAG milling can often be accomplished with fewer lines than in a conventional rod millball mill circuit. A diagram of types of AGSAG
2020-5-18By combining with SAG discharge and screening on the SAG discharge screens top sie control to the ball-mill circuit feed is maintained while still unloading the SAG circuit Mosher et al 2006. A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling while convenient this has the
