Minerals Free Full-Text An LSTM Approach for SAG Mill

Results show accuracies above 80% on both SAG mills at a short upcoming period of times and around 1% of misclassifications between soft and hard characterization. The proposed application can be extended to any crushing and grinding equipment to forecast categorical attributes that are relevant to downstream processes.

Minerals Free Full-Text An LSTM Approach for SAG Mill

SAG mills are located at the beginning of the comminution circuits, after a primary crushing stage. Although there are small SAG mills, their size usually ranges from 9.8 × 4.3 to 12.8 × 7.6 m, with a nominal energy demand of 8.2 and 26 MW, respectively [ 2 ], which make SAG mills the most relevant energy consumer within the concentrator.

What is the difference between a SAG mill and ball mill?

SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries.

Semi-autogenous grinding (SAG) mill liner design and

2016-6-6  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

SAG vs Ball Mills COMESA

By comesa_web Inglés. It’s important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don’t

Semi-autogenous grinding (SAG) mill liner design and

2007-8-1  SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell

Improved yields Mineral Processing at-minerals

2012-7-8  The actual comminution to particle sizes of around 5-10 mm is usually performed by autogenous or semi autogenous mills (SAG), which nowadays have diameters of up to almost 13 m, require a drive power of 25 MW and achieve throughput rates of 10 000 t/d. Ball mills installed downstream of SAG mills grind the ores to finenesses of less than 0.1 mm.
