Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, …

A 42-ft SAG mill was designed and built for Minas Congas mine in Peru, but never installed. "The rise from 34- to 40-ft-dia. SAG mills was quick, but then stalled," Filidore explained. "Today, we're seeing a lot of 28-ft ball mills. Last month, we sold six 28-ft ball mills and six 40-ft SAG mills.

This paper provides. a new liner parameter design and optimization method, which offers theoretical guidance for the optimization design of liner parameters.

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

Section snippets Model validation. To test the validity of the model data from 21 different full-scale AG/SAG mill circuits were used. The data comprised mill dimensions, grate design, mill speed, throughput, feed size distribution, product size distribution, power draw, ball load, ball size, normal operating load level and rock breakage characteristics …

In order to eliminate the impact of the accumulation of rock, the autogenous mill allows to add about 3% of the ball (Φ80 ~ Φ120), SAG mill steel ball filling is generally 8% ~ 12%, even up to 15%.

SAG mills contain balls of up to 150mm in diameter that occupy 5%-18% of mill chamber volume. Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion ...

This current study was carried out using a series of DEM simulations of a 3D slice of a generic SAG mill. The "generic" SAG mill, detailed in Table 1, was constructed to investigate the effect of lifter height/face angle (i.e. lifter wear state) and fill level on charge shape for a given rotational speed. The profiles used in this study for ...

Discrete Element Method simulation of charge motion in ball, SAG and autogenous mills has become a standard for lifter design, power draft evaluation, etc. Both two-dimensional and three-dimensional codes are being used. The two-dimensional code dominates the user market since the code completes a simulation in one or two hours.

Simulations indicated that a capacity increase of 12% would be achieved in the existing grinding circuit by further crushing 35% of SAG mill fresh feed. Such figures would represent yearly additions of 8.3 kt in copper and 250 kg in gold productions. Study. Minerals 2022, 12, 727.

viable tool. However, one could always claim the superiority of 3D DEM over 2D DEM for power predictions (Cleary 1998) which cannot be refuted by simple arguments. Further with 3D DEM a slice of SAG mill (Cleary 2001a) can be simulated to predict full mill power. A further advance in DEM model would be to change the shape of particles from disk or

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 with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
