proper supervision and instructions. 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
Installation Twin Pinion Sag Mill. SAG mill product feeds two parallel ball mills of 6.6 m 11.1 m internal diameter length, each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 3032 and 78.5 critical speed. The SAG mill trommel undersize is combined with the ball mills discharge … Ver artículo

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.
Girth gear drives – Fundamental Problems. 1.Axial/radial runout. 2.Alignment of the drive trains. 3.Uneven power splitting. 4.Centre distances variable. 5.Face load distribution. 6.Sealing of the girth gear. 7.Girth gear is through hardened only, fatigue strength is limited. -Dynamic behaviour.
STEP 5. Operating temperature and speed. STEP 6. Bearing interfaces. STEP 7. Bearing execution. STEP 8. Sealing, mounting and dismounting. The relationships between the temperature and power loss of components within an application is complex and these factors, in turn, have interdependencies with many others such as bearing sizes, loads …

For a double pinion drive the quantity is to be multiplied by 1,15. The gear cover should already be mounted to prevent dust from sticking on the tooth flanks before applying the priming lubricant BERULIT 443. BERULIT 443 also eases inspection of the contact pattern during the installation and alignment. By turning the gears with
The main gear is cut from a special gear steel casting and is made split and reversible. The pinion, usually integral with the pinion shaft, is cut from an alloy steel forging and heat treated prior to cutting the teeth. The pinion shaft is double ended so it is also reversible. All ball Mill gearing is designed in accordance with sound ...
Bearing internal clearance ( fig. 1) is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance). Initial internal clearance is the internal clearance in the bearing prior to mounting.

Aug 28, 2011Re Ball Mill Girth Gear and Pinion Alignment 08/27/2011 207 AM pinion alighnment is done by coating the pinion with a lead based grease. after rotating the drum, the grease marks will show the contact area. the pinion should contact the girth ring near the center of the gears.
This combination is called SLURRY. If this slurry gets onto the face of the bull gear it will act like sand paper when the pinion gear and the bull gear mesh together. It takes very little time under these conditions to wear a bull gear completely out. Where the bull gear is on the mill shell will affect how you shut your equipment down.
ring gear and pinion mesh after the installation of the components. These case-hardened and precision ground-pinions can be either grease or oil lubricated. Rigid pinion drive With this type of drive, the mill shell is driven via one or two pinions which transmit the motor power to the mill shell. Ring gear and pinion are usu-ally of the ...

Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
Processing girth gear of rotary kiln, what material wear resistance is high? The girth gear is one of the more commonly used parts in large mechanical equipment (such as rotary kiln, ball mill). Its function is to transmit and change the direction of force through the large ring gear. The large ring gear belongs to the thin-walled ring castings.
