get price! 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 ...
