Hardened & Ground Gear Boxes/Gears:
With more than 1000 girth gears sold over the world CITICIC Gear is a leading supplier in the cement and mineral industry. And as member of AGMA (American Gear Manufacturers Association), we do actively take part in defining the standard for gear rating calculations and service factors.
We provide girth gears in three different designs
Fabricated gears became more common in the past and are constructed with forged steel gear rim materials and electro welded body structure. The rings are manufactured from a whole block of high resistance alloy steel. After the rough machining of the ring, we carry out hardening and tempering heat treatment in order to improve the mechanical characteristic and therefore its relevant performance.
Avantages of fabricated girth gears
These features will reduce the lead time and costs. Fabricated manufacturing ensures a fast delivery.
This is especially beneficial in an emergency situation, where the existing gear rim is suffering from damage
Forging material process
• Final rolling
• Furnace cooling
• Control on production
• Water quenching
• Hardness testing
• Rough machining
• Ultrasonic testing and dimensional inspection
• Final inspection certification
• UNI EN ISO
Our girth gears are applied in the cement and minerals industries:
• Various types of horizontal mills
• Rotary dryers
• Rotary kilns
• Any other large gear ring application
CITICIC Gear invested in significant resources and achieved many innovations with pinions. The right combination of material, hardness and finishing between pinion and gear is crucial for a long lifetime of the installed equipment. We design and manufacture pinions to match every customers need, no matter how unique the situation might be.
We are leading supplier the Kiln Girth Gears for the various plants as listed below.
Gear Cutting Capacity:
The Kiln girth gears are available mainly in bi-part, four parts, 8 parts or multi segments as per the requirement and suitability with the application of gear.
In the field of grinding mill components, We supply mill heads,feed inlet,grinding roller,cement kiln riding ring, casting gears, shaft block .Also we supply mill shell of welding structures and fabrications.
