Girth gear also called gear ring, ball mill girth gear, kiln girth gear, is one of the main parts of a rotary kiln and ball mill. The girth gear needs to drive the whole cylinder to run for a long time, so the casting quality of the girth gear is required to be high. Due to the large modulus and diameter of the girth gear, the girth gear ...
Based on the MPT TITAN™ design, the Mills are girth gear & dual pinion driven with self-aligned flanged motors, running on hydrodynamic oil lubricated bearings. The TITAN design enables you to run full process load & 40% Ball charge at 80% critical speed – Max grinding power for every shell size. Standard Mill Types Available: Overflow Ball ...
a specific example, a 6,250kW ball mill gear at 16.76rpm output speed has a required rim thickness value of 210mm (8.26 in) in a tee configuration whereas the box Y gear has 165mm (6.51 in). This reduces the overall weight of the gear to 61,600 kg (135,700 lbs.) in a box Y con-figuration but 67,500 kg (148,700 lbs.) as a tee configuration.
The girth gear is one of the key components in the rotary kiln transmission. The installation quality directly affects the stability of the rotary kiln drive system, the stability of the rotary kiln operation, the service life of the kiln lining and the rotary kiln operation rate.
