The SAG mill discharge is classified on a trommel screen. In this application the SAG mill discharge is treated with a Trunnion Magnet or a drum type magnet to collect the grinding media as it discharges the mill. The Trunnion Magnet is replaces the trommel screen and removes grinding ball fragments directly from the mill discharge.

On Mill Installation and Maintenance. Before starting the erection of the mill, adequate handling facilities should be provided or made available, bearing in mind the weights and proportions of the various parts and sub-assemblies. This information can be ascertained from the drawings and shipping papers.

The efficient design of the Hurco 5-axis cnc trunnion table machining centers (U Series) is a key benefit to consider—we use an integrated trunnion table instead of simply sticking a trunnion table on a 3-axis machining center and passing it off as a 5-axis CNC machine. The integrated trunnion table design provides more clearance in the Z ...

The oil level can be seen at any time during operation to replenish the oil in time and avoid the occurrence of bearing damage accidents. AGICO trunnion bearing is made of ZG35 and ZG45 cast steel, which has high hardness, excellent wear resistance, strong bearing force, and small loss. It can work continuously for a long time.

The spilling of the sag mill over the feed trunnion indicates that the volume of slurry inside the mill (hold-up) has increased so much that the mill starts to operate similar to an overflow mill. This situation arises due to the poor performance of its discharge assembly, consisting of a very small size of pulp lifters.

The methods on how to manage the changing variables around SAG mills have improved over the years with new instrumentation and Advanced Process Control () systems. Despite these improvements, there is a gap between the available technologies and achieving the maximum potential of the SAG mill performance. The gap traditionally …

The Trunnion Magnet System bolts directly to the ball mill discharge flange to provide continuous magnetic collection of the grinding ball fragments. A permanent magnetic circuit collects the grinding ball fragments and …

Coupling of SPH to DEM to predict multiphase flow in mills was introduced as a 1-way coupling by Cleary et al. (2006a) with a 2-way version of this coupling in Cleary (2015a). Lichter et al. (2011 ...

Eriez Trunnion Magnets provide a unique system for separating and removing balls, chips or scats in a typical ball/SAG mill operation. This technology …

The mill noise and trunnion vibration signals were collected by a microphone and an accelerometer. The results showed that the characteristic power spectra energy of both the mill noise and vibration can represent the mill load accurately. ... To predict the power of the SAG mill, Hoseinian et al. proposed an analytical model based on gene ...

The amount of pebbles passing through the grate increases with the angle of the grate. It is imperative to ensure the efficient removal of both slurry and coarse pebbles (critical size) in order to ensure the efficient operation of AG/SAG mills. Elimination of the above mentioned material transport problems will allow the mill to respond truly ...

The slurry wheel upgrade is a retrofit sealing solution for the grinding mill feed end. The existing configuration is replaced with a new and improved slurry return system featuring a unique water-wheel design that significantly improves the material containment of the feed ends.

The Morrell C-model is generally regarded as one of the most accurate tumbling mill power-draw models and is ideally suited for this application of estimating fill levels of the SAG mill in real time.

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters). This is also called a 2-D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters
