In each mill, two pinions and gear units transfer the force from two 2250kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface. In spring 2017, an inspection of the drives revealed significant wear in the girth gears and pinions.
The proposed finite elementbased methodology accurately predicts the radial runout at the girth gear of an industrial ball mill. Discover the world's research 20+ million members
· How do you measure the root clearance between a girth gear and a pinion of a grinding ball mill and what is the recommended root clearance. This ball mill uses helical gears( 284 teeth girth gear with a 24 teeth pinion).
CHAENG girth gears are applied to the Xinjiang Tianshan Group, Henan Meng Group, and other wellknown domestic and foreign cement enterprises, for the normal operation of ball mill and rotary kiln. In 2011, CHAENG customized for the Turkish customers a large girth gear with diameter of meters and made up of GS34CrMo4 material, and received customer's high praise.
· The girth gear is the main transmission component of the ball mill and the rotary kiln. The girth gear is usually large in modulus and diameter, and generally adopts a radial structure, which is composed of two half gears. This structure determines that the girth gear will produce deformation during processing.
Ball Mill Girth Gear Radial How to install and align the girth gear and pinion prmdrive Jan 14, 2020 The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(b

Mill Girth Gear High Vibration Problem Case Study. A case study has been conducted on the wear problem of a set of large helical gears of a ball mill used for cement production at the shiraz cement plant the ball mill has a nominal capacity of 80 t h −1 the overall diameter and length are respectively 4000 mm and 12990 mm the total weight of the ball mill when fully charged is about 280 t.
Ball and rod mills are used to grind and process them further. Ball mills are heavyduty machines. The grinding process and the accepted ball motion flow inside the mill have an impact character. Drive gears are affected by impacts, which cause wear and tear on gear teeth and reduces operational life of gear trains and mills as a whole.
