Deliver Enquiry

With more than one thousand girth gears marketed more than the planet CZPT Equipment is a leading provider in the cement and mineral industry. And as member of AGMA (American Equipment Makers Association), we do actively get portion in defining the normal for gear rating calculations and service elements. 

We offer girth gears in 3 different styles

Fabricated steel
– cast ring
– rolled plate

Cast steel 

Ductile (Nodular) solid iron  

Fabricated gears turned a lot more frequent in the past and are built with forged metal gear rim materials and electro welded body composition. The rings are made from a total block of higher resistance alloy metal. Right after the rough machining of the ring, we carry out hardening and tempering heat remedy in purchase to increase the mechanical characteristic and consequently its appropriate performance.  

Avantages of fabricated girth gears

The forged materials construction excludes the danger of inclusions

Structure defects like fuel holes, CZPT shrinkage, pin holes, sizzling tears, sand and slag inclusions are avoided

That’s why, repair welding of the physique construction and e.g. grinding of toothed places is not essential.

The fabricated production treatment excludes the need for designs and risers

Rim content has increased hardness and higher energy than the materials employed for the fundamental construction (i.e. web, gussets)

These attributes will minimize the direct time and charges. Fabricated producing assures a quickly shipping.

This is specially useful in an crisis circumstance, where the present gear rim is suffering from damage   


External teeth 
Highest diameter: 16000 mm 
Toothed face width: 1700 mm 
Greatest module: 45 by hob 
Highest module: sixty five gear ending cutter

Inside teeth 
Maximum Diameter: 6500 mm 
Optimum module: twenty five.4 
Toothed encounter width: 400 mm

Forging materials process 
Last rolling 
Furnace cooling 
Handle on production 
Drinking water quenching 
Hardness testing 
Rough machining 
Ultrasonic tests and dimensional inspection 
Last inspection certification

Our girth gears are applied in the cement and minerals industries: 
Numerous varieties of horizontal mills 
Rotary dryers 
Rotary kilns 
Any other large equipment ring application

The specialized specifications of a big CZPT Equipment ring:
1) is pretreated prior to normalizing surface hardening therapy, the hardness need to HB210 ~ 250 mechanical efficiency are the ultimate energy Rb 690MPa, produce pressure Rs 490MPa, elongation D5 11%, reduction of region W 25% , effect toughness Ak 30J tooth induction hardened, hardness HRC50 ~ 55 effective hardened layer depth 3 ~ 5mm.
two) general ultrasonic flaw detection, internal quality should satisfy 2 needs GB7233-87 common specifications tooth and fillet magnetic particle inspection, top quality must meet 2 specifications GB/T9444-88 standards.
3) Be aware the casting is not rounded R5 ~ R10.
four) Tooth chamfer at both finishes and 1 45b.5) by 2 and a fifty percent ring gear tooth width of each and every ring CZPT along the edge of a entire ring created with large power bolts, blended with the tooth area have to be at the bottom heart.
