Girth Gear . Until the advent of frictional drives (see below), kilns only ever had one turning gear and this supplies all the torque to turn the kiln, so in the case of a long kiln, it is usually positioned somewhere near the middle (strictly speaking, the centre of mass) to minimise the amount of torsional distortion produced in the shell.
The spray bar should be set at a 30-degree angle to spray the open gear lubricant onto the drive or loaded side of the pinion or girth gear. Setting the spray angle at 30° (as shown in Figures 5.) will achieve a very good distribution of the lubricant in an upward or downward direction, always to the load-carrying tooth flank.
The girth gear is placed near to a kiln tyre so that it is accurately aligned with the rotary kiln axis, with minimal wobble. It is normal for the nearby tyre to be fixed in position with thrust rollers, so that as the kiln expands on warming up, the turning girth gear position remains fairly constant, while the nose and tail of the kiln expand ...

The rotating of the rotary kiln means passes the power to the shell and decelerates itself to the required speed. Every rotary kiln has a series of drive devices, generally composed of a motor, reduction box, big girth gear, and small girth gear. The common machines are the reduction box drive, gear drive, and triangle belt drive.

Girth Gear Pinion Infrared basics. The infrared alignment technique should only be applied to mill gear pinions not kiln or dryer gears. Kiln and drier systems typically run slow and do not develop sufficient temperatures from the mesh forces and can be significantly affected by heat transfer from the kiln or drum.
The national standard sets the maximum SO3 content at less than 3.5%, while our company controls it at 2.2±0.3%. 4. Control of Additions of Blended Materials. The addition of blended materials in cement production can, on the one hand, improve certain properties of the cement and reduce cement costs.

Vertical Kilns Vertical Shaft Kiln Structures & Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer.Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.
