Ball Mill GEAR GUARD. A plate steel gear guard is furnished with the mill for safety in operation and to protect the gear and pinion from dirt or grit. As soon as the gear and pinion have been cleaned and coated with the proper lubricant, the gear guard should be assembled and set on its foundation.

Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...

A common failure cause of gear driven mill systems is misalignment, which in its most severe form can cause rapid tooth fatigue and fracture. The operating temperature profile of girth gear pinions give an indication of the pinion's overall alignment with the girth gear. High differential temperatures from end to end indicate misalignment.

girth gear sag mill commissioning,both the sag mill and ball mill are each driven by two gear units. because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about MW per drive is in effect. with the DM gear units, siemens said this limit expands to as much as MW per drive.

girth gears or the single-helical SAG mill girth gear from David Brown (England) delivered in 2008 for a mining opera-tion in Armenia. (A gear that weighed more than 65,000 kilograms [143,300,30 lbs] boasted 362 teeth, 0.75 DP, 863.6 mm face width, 12.4m OD and a 10.5 m diameter bore). At that time, David Brown had claimed the size record.

SAG Mill Circuit Sampling. Many mills have been built based on data from inadequate sampling or from insufficient tests. With the cost of many mills exceeding several hundred million dollars, it is mandatory that geologists, mining engineers and metallurgists work together to prepare representative samples for testing.
