misaligenment girth gear cement mill process

Each day, the 15-meter-long machines grind up to 5000 metric tons of clinker – the result is ready-to-use Portland cement. In each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.

The girth gear driving pinion ends up getting aligned to the reduc-er, causing a misalignment issue between the girth gear teeth and the driving pinion teeth (Fig. 1). – Proper alignment should consist of: axial and radial alignment of the girth gear to the center line of kiln/mill; center line of the driving pinion is aligned to the center line

The cement mill is driven at 16 rev min"1 by a girth gear fitted to the head wall. The girth gear is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor. The speed ratio between the pinions and the girth gear is 7:1. The girth gear mounting on the mill shell is shown in Fig. 1.
