หลักการทำงาน
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.
ข้อได้เปรียบหลัก
Reinforced gear sets and housings withstand the heavy cyclic impacts from grinding media and material.
Delivers reliable output torque up to 2,200 kNm for large ball mills and vertical roller mills.
Forced oil lubrication with integrated cooling maintains stable temperatures during 24/7 grinding operations.
Wear-resistant gear tooth profiles and robust sealing extend operational life in dusty mineral processing environments.
Available in single or dual-pinion arrangements to match mill power requirements and layout constraints.
Engineered to match existing mill girth gears, pinion stands, and foundation requirements.
โครงสร้างและงานฝีมือด้านวัสดุ
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.
ตัวอย่างการใช้งานทั่วไป
Ball Mills in Mining: Provides reliable high torque for grinding ore in mineral processing plants operating under heavy continuous loads.
SAG Mills: Handles the combined impact and grinding forces in semi-autogenous grinding operations with large feed sizes.
Cement Vertical Roller Mills: Delivers precise torque to grinding rollers while withstanding the high axial and radial forces in clinker grinding.
คู่มือการเลือก
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.

คำถามที่พบบ่อย
Q: What service factor is recommended for ball mill applications?
A: A minimum service factor of 2.0–2.5 is recommended due to the heavy shock loads from grinding media and material.
Q: How is lubrication managed in continuous grinding operations?
A: Forced oil lubrication with integrated oil cooling and filtration systems maintains stable temperatures and protects components during 24/7 operation.
Q: Can these gearboxes be supplied in dual-pinion configuration?
A: Yes. Both single-pinion and dual-pinion arrangements are available to match mill power and layout requirements.
Q: What maintenance is critical for mining mill gearboxes?
A: Regular oil analysis, vibration monitoring, and scheduled inspection of gear tooth condition help prevent unplanned downtime in remote mining operations.
Q: Are custom cooling systems available?
A: Yes. External oil coolers and enhanced cooling jackets can be integrated for high ambient temperature or high-power applications.
กรณีศึกษา – บันทึกภาคสนามของวิศวกร
เปรู – Large copper concentrator in the Andes. Two dual-pinion ball mill gearboxes (2,000 kW each) were installed during a plant expansion. The units have operated continuously for over 20 months with excellent thermal stability and zero unplanned stoppages.
Turkey – Major cement plant near Ankara. Three vertical roller mill gearboxes were supplied for a new clinker grinding line. Post-commissioning testing confirmed vibration levels well below acceptance criteria and stable performance under full load.
แอฟริกาใต้ – Platinum group metals processing plant. A heavy-duty SAG mill gearbox was installed to replace aging equipment. The new unit increased grinding capacity while reducing lubricant consumption and maintenance frequency.
