Ball Mill GEAR GUARD. A plate steel gear guard is furnished with the mill for safety in operation and to protect the gear and pinion from dirt or grit. As soon as the gear and pinion have been cleaned and coated with the proper lubricant, the gear guard should be assembled and set on its foundation. DISCHARGE HOUSING "Doghouse"
This situation may cause the ball mill to tilt. The meshing of the large ring gear and the pinion gear will form an axial angle, which will cut the teeth each other, which will increase the difficulty of meshing, cause loud noise and increase the vibration, and will cause the ball mill to stop in severe cases.

mill and two 24' x 39.5' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. Copper Mountain has installed on all three mills, the new state-of-the art dual pinion mill drives. All the inherent operation and maintenance features of this
The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling …
Valuable information on the gear condition is obtained from the sideband index. 1. INTRODUCTION The pinion (Fig. 1) is driving the ring gear of the ball mill. The total power transmitted through the system is 4 MW. The plant had a record of pinion failures over approximately 3 years.

The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.
