The method can be applied for any kind of synchronous mill motor. ... Grinding power is split into the SAG and ball mills. Commonly, when the SAG mill stops its operation, the other two ball mills should also halt Fig. 3 outlines the charge motion in the mill. The lifters lift the load and produce cascade and cataracting.

When the Sag Mill was in operation the clutch operation just did not look ok and pad wear was uneven. The clutch was changed with a used clutch and the results were significant. The axial vibration on the Sag NDE bearing axial plane reduced from 30mm/sec rms to under 2mm/sec rms. The motor vibration is now satisfactory in all planes.

When it Comes to Mining, Bigger is Best | PTE. An SABC circuit consists of a semi-autogenous grinding (SAG) mill, ball mill, and crusher. A ball mill is a slightly inclined, horizontal rotating cylinder, partially filled with ceramic balls, flint pebbles or stainless steel balls, that grinds material to the necessary fineness by friction and impact with tumbling balls (Fig. 2).

This paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase synchronous machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause tripping and equipment damage. The consequences of voltage sags on the machine behaviour depend on different factors such as sag's magnitude (or depth), …
