The main components of a SAG mill are transmission structure, roller, slow drive, and feeding. and discharging device. The working principle of a SAG mill is as follows: the main motor drives.
Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm).

operation of SAG mills. SAG mills are currently the technology of choice in hard rock milling operations for reducing primary-crushed ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m (34 ft) and above, with the largest being 12.2 m (40 ft) in
Keywords: IGBT, IEGT, 3-level in verter, mill main drives, Fixed Pulse Pattern, hot strip mill INTRODUCTION DC drives and cycloconverters have been used in rolling mill applications for many years. The appearance of the IEGT (Injection Enhanced insulated Gate bipolar Transistor) or IGCT/GCT made the large PWM drive system practical.
Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, which directly affects the impact speed and ...
