Raw Material Drying-Grinding. Larger mills have a twin drives of half the ratings on either side of same girth gear. In central drive arrangement both the girth gear and pinion are avoided by connecting gear box output shaft directly to mill. Mechanical separators Mill discharge material is fed onto a rotating dispersion plate whence it

For example, the large girth gear of the ball mill is installed in the middle of the ball mill. From the mechanical point of view, the center of the ball mill cylinder will bear a large bending moment, and the load is vertically downward, so the middle load of the cylinder will also be The deflection caused by bending deformation and thermal bending deformation is relatively large.

Girth gears are extensively used in most of the mills and kiln drive system. These gears are one of the highest cost components in the entire drive assembly. The girth gears have a very big diameter and high precision finish. The girth gears have a high efficiency and its overall life depends upon the proper lubrication and alignment.

turn the girth gear around on the mill and run it on the back flank. In order to maintain alignment of the girth gear and mill pinion, standard practice in the industry is to measure the temperature difference across the face width of the girth gear. The David Brown standard is a maximum temperature difference (DeltaT) of 6 degrees
