With a lot more than one thousand girth gears sold over the planet CITICIC Gear is a leading provider in the cement and mineral market. And as member of AGMA (American Equipment CZPT rs Affiliation), we do actively just take component in defining the normal for equipment rating calculations and provider elements. 
We provide girth gears in three various types
Fabricated steel
– cast ring
– rolled plate
Forged steel 
Ductile (Nodular) forged iron  
Fabricated gears became much more widespread in the past and are created with solid steel equipment rim components and electro welded body framework. The rings are created from a entire block of high resistance alloy steel. Soon after the rough machining of the ring, we have out hardening and tempering warmth remedy in order to improve the mechanical attribute and for that reason its appropriate efficiency.  
Avantages of fabricated girth gears
The forged material construction excludes the chance of inclusions
Structure defects like fuel holes, micro shrinkage, pin holes, hot tears, sand and slag inclusions are averted
That’s why, restore welding of the human body construction and e.g. grinding of toothed places is not required.
The fabricated production process excludes the need for styles and risers
Rim materials has higher hardness and greater toughness than the material employed for the underlying framework (i.e. net, gussets)
These characteristics will decrease the guide time and fees. Fabricated producing assures a CZPT delivery.
This is specially helpful in an crisis scenario, exactly where the existing equipment rim is suffering from damage   
Exterior teeth 
Optimum diameter: 16000 mm 
Toothed experience width: 1700 mm 
Optimum module: 45 by hob 
Optimum module: sixty five equipment finishing cutter
Interior teeth 
Greatest Diameter: 6500 mm 
Greatest module: twenty five.4 
Toothed experience width: 400 mm
Forging material process 
Final rolling 
Furnace cooling 
Handle on production 
Water quenching 
Hardness testing 
Tough machining 
Ultrasonic testing and dimensional inspection 
Closing inspection certification

Our girth gears are utilized in the cement and minerals industries: 
Numerous varieties of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other huge equipment ring software
ZTIC Gear invested in significant methods and attained a lot of improvements with pinions. The right mixture of material, hardness and ending among pinion and gear is critical for a CZPT lifetime of the mounted gear. We layout and manufacture pinions to match each CZPT ers need to have, no make a difference how exclusive the predicament may possibly be.
