Henan San Kuang Machinery Technology Co., Ltd. is proud to present our Mining Ball Mill Split Ring Gear – 18 Module, 40Cr Wear Resistant Segmented Structure. As a trusted manufacturer since 2014, with a factory spanning 10,000–30,000 square meters and an annual export value exceeding US$2.5 million, we understand the critical demands of the mining industry. Our split ring gear is engineered to deliver exceptional durability, precise power transmission, and easy maintenance for large-scale ball mills. This product combines the strength of 40Cr alloy steel with a segmented design, ensuring reliable operation under heavy loads and harsh environments.
The 18 module configuration is specifically designed for high-torque applications in mining ball mills, where continuous operation and wear resistance are paramount. Each gear segment is manufactured using advanced heat treatment and precision machining processes, resulting in a surface hardness that significantly extends service life. The segmented structure allows for simplified transportation, installation, and replacement – reducing downtime and maintenance costs. Whether you are upgrading an existing mill or building a new one, our split ring gear offers a cost-effective solution without compromising on quality.
Key Product Features
- Segmented Design: Each ring is divided into 2–4 segments (customizable) for easy handling and installation in confined spaces. No need for heavy lifting equipment.
- Premium Material 40Cr: Alloy steel with chromium content provides excellent hardenability, toughness, and wear resistance. Suitable for high-stress environments.
- 18 Module Precision: Meticulously cut teeth with module 18 ensure smooth meshing with pinion gears, minimizing vibration and noise.
- Heat Treatment: Quenching and tempering process delivers a uniform hardness of HB 240–280, with optional surface hardening (carburizing or nitriding) available upon request.
- Wear Resistance: The combination of material and heat treatment results in 2–3 times longer service life compared to standard 45# steel gears.
- Customizable Dimensions: Outer diameter, tooth count, segment quantity, and bolt hole patterns can be tailored to your specific mill specifications.
- Rigorous Quality Control: Each gear is inspected for dimensional accuracy, tooth profile, and material hardness. Our factory holds ISO9001, ISO14001, OHSAS18001, and other certifications.

Advantages for Your Mining Operation
- Reduced Downtime: Segmented design allows partial replacement without dismantling the entire mill. Quick installation saves days of maintenance.
- Enhanced Durability: 40Cr material with optimized heat treatment resists abrasive wear, pitting, and tooth breakage under heavy loads.
- Improved Efficiency: Precise tooth geometry ensures uniform load distribution, reducing energy loss and extending gear life.
- Global Logistics: Our factory is located in Luoyang, Henan, with convenient access to major ports (Shanghai, Qingdao, Tianjin, Lianyungang). We export to over 15 regions worldwide.
- Full Customization: We work with your drawings or reverse-engineer existing gears. 3D modeling and FEA analysis are available for complex designs.
With over 10 years of experience in heavy machinery manufacturing, Henan San Kuang has supplied ball mill gears to customers across North America, South America, Europe, Africa, Southeast Asia, and Oceania. Our team of 51–100 skilled engineers and workers ensures strict adherence to international quality standards.

Frequently Asked Questions (FAQ)
1. What is the difference between a segmented split ring gear and a one-piece gear?
A segmented ring gear is divided into 2–4 pieces that are bolted together to form a complete ring. This design allows easier transportation, handling, and installation, especially for large-diameter gears (e.g., over 4 meters). It also enables partial replacement if only one segment is damaged, reducing downtime and cost.
2. Why is 40Cr material chosen for this gear?
40Cr alloy steel contains 0.8–1.1% chromium, which improves hardenability, strength, and wear resistance. After quenching and tempering, it achieves a good balance of toughness and hardness, making it ideal for mining ball mill applications where high impact and abrasive wear occur.
3. Can you manufacture gears with a different module or tooth count?
Yes, we can customize the gear according to your specifications. The module, number of teeth, outer diameter, and segment quantity can all be adjusted. Please provide a drawing or detail requirements for a quotation.
4. What is the typical lead time for this product?
For standard sizes (e.g., outer diameter ≤ 6,000 mm) and common material, lead time is approximately 45–60 days after order confirmation. Custom designs may require 60–90 days, depending on complexity.
5. Do you offer on-site installation supervision?
Yes, we can dispatch experienced engineers to supervise the installation and alignment of the ring gear. This service is available upon request, with travel and accommodation costs borne by the client.
6. How do you ensure the quality of the gear teeth?
We use CNC gear hobbing and shaping machines with precision cutters. Each tooth profile is inspected with a gear tester, and the overall gear runout is measured. Our quality control system follows ISO9001 procedures, and we provide material certificates and inspection reports.
7. What is the maximum hardness you can achieve?
Standard hardness is HB 240–280. For higher wear resistance, we can apply carburizing and quenching to achieve a surface hardness of HRC 58–62, with a core hardness of HRC 30–40. This option is recommended for extremely abrasive materials.
8. Do you export to my country? Which ports do you use?
We export globally to markets including North America, South America, Europe, Africa, Southeast Asia, Oceania, and the Middle East. Our main shipping ports are Shanghai, Qingdao, Tianjin, and Lianyungang. We can arrange sea freight, air freight, or door-to-door delivery as needed.
