Import Girth Gear For Ball Mill & Rotary Kiln — Buy in Bulk from Supplier in China

Great Wall Steel Casting Co., Ltd. supplies girth gears specifically engineered for ball mills and rotary kilns, key components that stabilise the transmission systems of these rotating equipment. The gears are cast from ZG45 or ZG42CrMo steel, materials known for their high strength and wear resistance in abrasive environments. Each gear weighs between 10 tonnes and 80 tonnes, reflecting the large dimensions required for heavy‑duty applications. The supplier emphasizes the need for clear engineering drawings to match the casting to the machine specifications.

In the casting industry, ZG45 and ZG42CrMo are standard grades that are typically heat‑treated to achieve a hardness suitable for high‑load transmission, often around 250 - 350 HB. Typical tolerances for large cast girth gears include a dimensional accuracy of ±0.5 mm for critical diameters and a surface roughness of Ra 1.6 µm. Standard practice also involves post‑casting machining of the tooth profile to meet ISO 1328 involute specifications. Buyers can request additional treatments such as nitriding or carburising to extend service life.

Primary customers are mining, cement and steel plants that require robust gear solutions for continuous operation. Great Wall Steel Casting Co., Ltd. can ship worldwide but does not disclose MOQ, lead time or payment conditions in the listing, so these details must be clarified with the supplier. Prospective importers should discuss packaging, freight terms and any required export certifications before finalising the contract.
