With far more than 1000 girth gears bought over the world CZPT Equipment is a leading provider in the cement and mineral business. And as member of AGMA &lparAmerican Gear Makers Association), we do actively take component in defining the standard for equipment score calculations and service variables. 
We provide girth gears in 3 diverse styles
Fabricated steel
– forged ring
– rolled plate
Solid steel 
Ductile &lparNodular) cast iron  
Fabricated gears turned more widespread in the past and are constructed with solid steel equipment rim resources and electro welded physique composition. The rings are created from a total block of large resistance alloy metal. Right after the rough machining of the ring, we carry out hardening and tempering heat treatment in buy to improve the mechanical characteristic and for that reason its pertinent efficiency.  
Avantages of fabricated girth gears
The solid material composition excludes the risk of inclusions
Structure flaws like gasoline holes, CZPT shrinkage, pin holes, sizzling tears, sand and slag inclusions are averted
Consequently, fix welding of the entire body structure and e.g. grinding of toothed locations is not essential.
The fabricated production process excludes the want for patterns and risers
Rim materials has larger hardness and increased power than the material used for the underlying construction &lpari.e. world wide web, gussets)
These features will reduce the guide time and charges. Fabricated production ensures a fast shipping.
This is specially beneficial in an emergency circumstance, where the current equipment rim is struggling from damage

The recommended components for the worm are hardened steel and bronze for the worm gear. Nonetheless, relying on the software, unhardened steel worms can run sufficiently and much more economically on solid iron worm gears rated at 50%. In addition to steel and hardened metal, worms are offered in stainless metal, aluminum, bronze, and nylon worm gears are obtainable in metal, hardened metal, stainless metal, aluminum, nylon, and non-metallic (phenolic).
