simulasi grinding sag mill

1 Introduction. In mining, a Semi-Autogenous Grinding mill (SAG) is the equipment used at mineral processing plants in the size reduction process, making the ore suitable for the next stage of flotation. Its use lies in significant processing and reduction capability offered by this kind of mill, where maximize the operational continuity and ...

The SAGDesign test was developed by the SAGDesign Consulting Group (Starkey, Hindstrom & Nadasdy, 2006) and consists of a batch grinding test conducted in a 0.488m diameter SAG mill. About 10kg of drill core is required for testing. The feed is prepared to 80% passing 19mm and ground to 80% passing 1.7mm.

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. … See more

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The experimental study was carried out in a lab-scale planetary ball mill (Droide®, Shanghai). As shown in Fig. 1, the planetary ball mill contains a disk and four grinding bowls, each with a capacity of 1000 mL.For a clearer explanation, a simplified diagram is used, as shown in Fig. 2.The centers of rotation and revolution are O r and O R, …
