2. Grinding mill circuit 2.1. Process Description A single-stage closed run-of-mine (ROM) ore milling circuit, as shown in Fig. 1, is considered in this study. The circuit consists of a semiautogenous (SAG) mill with an end
This included the bench-marking and optimization of the SABC comminution circuit, focusing on the primary (SAG mill) and secondary (ball mill) grinding mills, and estimating the outcomes of changes to circuit operating
Grinding circuit efficiency is critical for the performance of the whole ore beneficiation process. Outotec's ACT grinding optimization system – with the RockSense on-belt rock size analyzer, MillSense charge analyzer, and PSI particle
Sagmilling.com is home to a collection of both free and subscription-based calculation tools to aid metallurgical process engineers perform comminution calculations. Grinding circuit design tools, including for SAG mill-ball mill
2014/08/12· The results in SAG-Mill line 2 are even more dramatic. Because of segregation on the coarse feed stockpile, SAG-mill 2 receives a higher percentage of coarse material. The KnowledgeScape strategy's ability to maintain smooth and stable operation of the mill was more apparent when contrasted to the DCS control on the …

This paper discusses the development of the Batu Hijau Milling Circuit Configuration Strategy, which incorporates mine ore scheduling, mill shutdown planning, SAG Mill discharge grate, trommel and pebble screen panel aperture
The value T80 is the "synthetic" transfer size between the SAG mill and ball mill – a fines-corrected 80% passing size 2 of the SAG mill product (or the combined SAG mill product and crushed pebbles if the circuit is sending crushed pebbles to the ball mill circuit, a.k.a. SABC-B operation).
The SAG Power Index (SPI) test (Starkey & Dobby, 1996) uses a benchscale SAG mill test to - determine the specific energy of an industrial SAG mill. The test is operated in closed circuit and the time required to grind the 80
Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product
optimization of the SABC comminution circuit, focusing on the primary (SAG mill) and secondary (ball mill) grinding mills, and estimating the outcomes of changes to circuit operating parameters (e.g., feed rate, mill load, ball charge, etc.).
The Grinding Circuit optimization Application is the first technology to accurately predict critical SAG Mill performance variables. It then correlates this data to give an accurate picture of conditions inside the mill.
2017/03/17· When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit …
