Cast Steel Girth Gear Heavy Duty Ring Gear for Ball Mill Mining Cement Equipment

Large Split Cast Steel Girth Gear Heavy Duty Ring Gear for Ball Mill Rotary Kiln Mining Cement Equipment

Product Description

The girth gear also known as ring gear is the core power transmission component for large rotary equipment. It is widely adopted on ball mills rotary kilns and other heavy rotating machinery used in mining mineral processing and cement industries. This split type girth gear adopts segmented casting design which greatly lowers the difficulty for transportation on site installation and maintenance compared with one piece large gear. The gear tooth surface is processed precisely to ensure stable meshing low vibration and long service life under continuous heavy load working conditions.

We specialize in the production of high end industrial castings with a wide range of material selections including high manganese steel high chrome cast iron alloy steel and ductile iron. Our main product portfolio covers various wear resistant liners for ball mill jaw crusher AG mill and SAG mill and a full range of mining machinery spare parts. We support OEM and ODM customized manufacturing according to customer technical drawings samples or working condition requirements. Our foundry has rich experience in producing ultra large heavy castings for global mining and cement projects.

Applications

1. Ball mill main driving gear for ore grinding in mineral processing plant
2. Rotary kiln transmission gear for cement and metallurgy calcining production
3. Other large rotary industrial equipment requiring heavy torque transmission It can work stably under heavy load dusty and continuous operation environment common in mining and cement sites.

Production and Quality Inspection

All girth gear castings will go through professional heat treatment process to refine internal grain structure eliminate casting stress and achieve stable mechanical performance and target hardness value. We implement comprehensive multi item inspection for each gear during production. The inspection items include hardness test 3D scanning magnetic particle test MT ultrasonic test UT chemical composition analysis dimension inspection and metallographic analysis. Chemical composition analysis controls the alloy element proportion strictly to meet the material standard. Hardness test verifies the mechanical property of gear blank and tooth area. 3D scanning is used to check the overall contour and gear tooth profile. MT and UT non destructive testing detect internal and surface casting defects. Metallographic analysis checks the microstructure of the casting. Full dimension inspection guarantees all sizes match customer drawing requirements. Every girth gear will pass full inspection before shipment to ensure reliable transmission performance and reduce unexpected downtime for end users.

Support and Services

We provide complete professional technical support through the whole project. Our team can assist customers on material selection gear module design calculation working condition evaluation and on site installation guidance. We can supply formal original inspection reports including material certificate hardness report non destructive test reports as customer required. We accept customized production for different gear sizes modules and materials. Our team has abundant export experience of large heavy castings and is familiar with international project standards for mining and cement equipment spare parts. We can respond quickly to technical inquiries and quotation requests.

Packing and Shipping

We adopt export standard fumigated wooden case packing for protection. The large girth gear will be fixed firmly inside the package with support structure to prevent collision and deformation during sea transportation. Anti rust coating will be applied on gear tooth surface before packing for long sea voyage storage. We mainly arrange sea shipment for such heavy large castings. We can cooperate with customers to handle packing marking and shipment arrangement according to your shipping plan and port requirements.
