The style of a SAG mill liner is driven by the material of building and construction and also the application, as well as limited by casting, molding, and taking care of constraints. For huge mills with wide inlet trunnions, in excess of 1.5 m, liner handling types of equipment are currently in common usage, and also this has actually permitted the development of large …

calculations define the efficiency of a fine stage-crush ball mill circuit as 1.0 to 1.2 depending on ball mill feed size, and some SABC (SAG/ball mill/pebble crusher) circuits operating with an efficiency of 1.3-1.4 or higher on coarse feed.

The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.

In this thesis, two modeling techniques are proposed for simulating the dynamics in the grinding process. The first method is the fundamental modeling method, where the underlying

According to the different grinding media and grinding materials, the mill can be divided into: ball mill, rod mill, AG mill, SAG mill, vertical mill and so on.When working, the motor rotates the cylinder through the transmission gear, sprocket or belt, and the centrifugal force generated will bring the grinding media and materials to a certain height and then fall, which will produce …

A controller was implemented between SAG mill and feeder, so the SAG mill hold-up was controlled below a certain level i.e. a constant mill charge. The intention was to explore how much the final throughput would be changed by controlling cone crusher settings where the SAG-mills capacities are limited.

Example crushing flowsheets feeding a: (a) rod mill, and (b) SAG mill with a "recycle" (pebble) crusher to size reduce "critical size" material. One of the main reasons for closing the circuit is the greater flexibility given to the crushing plant as a whole.

SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.

SAG mill by feeding crushed pebbles The standard destination for crushed pebbles has been to return them to SAG feed. However, open …

So, a typical processing line at a mine might consist of a crusher followed by a SAG mill or a ball mill. In this context, grinding mills like ball mills are considered grinders rather than crushers. applications. A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an ...

The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems. 9.1. In an SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9, respectively.

After closed-circuit secondary crushing, the SAG mill feed 80% passing (F80) size was 25 mm to 30 mm. Installed grinding power is split equally between the two mills with the SAG mill fitted with a variable speed drive (VSD). SAG discharge screen oversize ('pebbles' or 'scats') was recycled through an 185 kW pebble crusher.
