The equation uses mill dimensions (inside the liners), the density of the mill charge and an empirical "power number" that encapsulates the mill speed and volumetric filling.
WhatsApp: +86 18838072829Early SAG mill designs using gear drives were limited in the amount of power that could be applied to the pinions, MPa (5000 hp). The exception to this design was the Hibbing taconite operation. It used MPa (6000 hp) motors to drive a 1Imdiam x long (36ftdiam x 15 ft) autogenous mill. However, recent SAG mill designs now ...
WhatsApp: +86 18838072829Due 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 ...
