Speaker Dr Francisco Reyes, Research Fellow, JKMRC Abstract SAG mills are a key asset for mineral processing operations as one of the critical stages of extracting mineral out of ore, and their continued stable operation is central to productivity. However, the performance of a SAG mill changes rapidly in response to conditions such as feed size and hardness as well as longer-term ...
SAG mills. The prospect of achieving maximum increases in the throughput of existing grinding plants also make the POLYCOM a popular machine for plant extensions. Thanks to its low space requirement and high capacity in relation to machine size, the POLYCOM can be easily incorporated into existing plant configurations.
Comminution is an essential component of mineral processing operations and its proper operation and design is vital to ensure that the plant operates efficiently. In recent years, there has been a shift of emphasis on ball mill optimization to semi-autogenous grinding SAG mills.
Jan 01, 2016 The SAG mill had a 68 ball charge and the power consumption was 8 kWht, 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

inside the mill and it is composed of balls, ore and water. The ball charge is a function of the bulk fraction of the SAG mill volume Jb occupied by balls the ore retained in the mill is the result of the volumetric lling which depends on the ore size distribution spe-cially the 600 and the 600 100, on the rotational speed NNc

EGL SAG mill driven by a 24,000 kW gearless drive. The SAG mill feeds two FLSmidth ball mills each 26 ft. in diameter 40 ft. long EGL, each driven by a 16,400 kW drive. The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft. SAG mill in Peru Garcia amp Villanueva, 2013 1.
With the new equipment, the plant expects to double its ore processing capacity and increase gold production, according to Metso. Metsos delivery consists of the primary crushing station with a Nordberg C160 jaw crusher, one SAG mill and two ball mills
A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006. 12.1. An alkaline slurry from a bauxite grinding mill was scheduled to be classified using a spiral classifier at the underflow rate of 1100 tday. The width of the classifier flight was 1.3 m and the outside diameter of the spiral flights was 1.2 m.
Mineral processing operations present many challenges for automatic process control due to variations in unmeasured ore properties, material transport delays, and nonlinear response characteristics. Control of -SemiAutogenous GrindingSAG mill weight is an example of an important process that exhibits many of these aspects.
