Girth gear cleaningflushing mill and kiln girth gear drives. globals bull gear cleaning programs are designed to remove contamination and lubricant buildup on bull gears and pinions prior to inspection. this is accomplished by flushing the bull gear while in production, which minimizes downtime.
Girth gear isotary kiln, mill main transmission parts and other equipment, mainly driven by the motor pinion drive, pinion drive mounted on the barrel ofarge gear, so that the mill drive, large gear and the barrel cooperation. due to the girth gear modulus big, big diameter, the ring gear of our company processed using radiation plate.
Girth gears are large ring gears which are normally fitted to the outside of ball mills or rotary kilns to provide the primary rotational drive, which is required to be operated inong time. so, the quality requirements during the actual production for the big gear ring are very high.
Girth gears fall into two basic categories flange mounted and tangential spring mounted. flangemounted girth gears, the more common of the two, are most frequently utilized in cold processing equipment such as sag semi autogenous grinding mills and ball mills for use in the mining and cement industries. by current standards, girth gears can be as large as 14.
Girth gears. withariety of options for cast, fabricated steel or sg iron and multisegmented gears, david brown santasalo is your one stop shop for girth gears for ag, sag, ball mill and crushing applications. engineered in segments, starting from two and with no upper limit, we can manufacture girth gears up to 14 metres diameter.
High efficiency level as no coupling required on the mill side the choice is yours. girth gear and pinion drives are sufficient for up to 4,500kw. our integral drive is suitable for up to 6,500kw. for mills withrive power of between 5,000 and 10,000kw, we recommendlassic central drive with fixed planetary gears.
