Principe de fonctionnement<\/h2>\n

Power from the main drive motor is transmitted through multi-stage helical or planetary gear arrangements. The high-torque low-speed output shaft connects directly to the mill pinion or girth gear. Advanced forced lubrication and cooling systems maintain stable operation under continuous heavy grinding loads, while reinforced housings absorb the cyclic shock forces generated during the grinding process.<\/p>\n

Principaux avantages<\/h2>\n
1. Exceptional Shock Load Handling<\/strong><\/p>\n

Reinforced gear sets and housings withstand the heavy cyclic impacts from grinding media and material.<\/p>\n<\/div>\n

2. High Continuous Torque Capacity<\/strong><\/p>\n

Delivers reliable output torque up to 2,200 kNm for large ball mills and vertical roller mills.<\/p>\n<\/div>\n

3. Advanced Lubrication Systems<\/strong><\/p>\n

Forced oil lubrication with integrated cooling maintains stable temperatures during 24\/7 grinding operations.<\/p>\n<\/div>\n

4. Long Service Life in Abrasive Conditions<\/strong><\/p>\n

Wear-resistant gear tooth profiles and robust sealing extend operational life in dusty mineral processing environments.<\/p>\n<\/div>\n

5. Dual and Single Pinion Configurations<\/strong><\/p>\n

Available in single or dual-pinion arrangements to match mill power requirements and layout constraints.<\/p>\n<\/div>\n

6. Custom Mill Interface Design<\/strong><\/p>\n

Engineered to match existing mill girth gears, pinion stands, and foundation requirements.<\/p>\n<\/div>\n

Savoir-faire en mati\u00e8re de structure et de mat\u00e9riaux<\/h2>\n

Housings are fabricated from high-strength steel or cast in QT500 ductile iron with internal reinforcements. Gears are precision ground from case-hardened alloy steel. Large-diameter output shafts and heavy-duty bearings handle combined radial and axial loads from the mill. Forced lubrication systems with oil coolers and advanced sealing maintain performance in continuous grinding operations.<\/p>\n

\"Grinding<\/p>\n

Sc\u00e9narios d'application typiques<\/h2>\n

Ball Mills in Mining:<\/strong> Provides reliable high torque for grinding ore in mineral processing plants operating under heavy continuous loads.<\/p>\n

SAG Mills:<\/strong> Handles the combined impact and grinding forces in semi-autogenous grinding operations with large feed sizes.<\/p>\n

Cement Vertical Roller Mills:<\/strong> Delivers precise torque to grinding rollers while withstanding the high axial and radial forces in clinker grinding.<\/p>\n

\"Cement<\/p>\n

Guide de s\u00e9lection<\/h2>\n

Calculate required output torque based on mill power and grinding media load. Determine the target mill speed and select the appropriate ratio. Consider single or dual-pinion configuration based on mill size and power. Evaluate mounting orientation, foundation strength, and ambient conditions. Review thermal capacity for continuous operation and specify any requirements for forced lubrication or external cooling. Confirm compatibility with existing mill girth gear or pinion interface.<\/p>\n
