Jiangsu Manqi Machinery Co., Ltd. is proud to present the MBY710 Jinxiang Ball Mill Gearbox – a robust, high-performance drive solution engineered for demanding ball mill applications. With a rated power of 1250 kW and a wide ratio range of 8.0:1 to 11.2:1, this helical-bevel gearbox delivers exceptional torque transmission while maintaining remarkably low noise levels. As a manufacturer with over 7 years of experience and a modern facility spanning 10,000–30,000 square meters, we design and produce gearboxes that meet the rigorous needs of mining, cement, and bulk material processing industries worldwide.
Key Features and Benefits:
High Power Density: The MBY710 handles up to 1250 kW, making it suitable for large-scale ball mills in mineral processing and cement grinding.
Helical-Bevel Gear Design: Combines helical gears for smooth, quiet operation with bevel gears for efficient right-angle power transmission – ideal for confined spaces.
Low Noise Operation: Precision-ground gears, optimized tooth profiles, and rigid housing keep noise levels ≤78 dB(A) under typical load, improving working conditions.
Wide Ratio Flexibility: Adjustable ratio range 8.0–11.2 allows matching mill speed requirements without additional external gearing.
Robust Construction: Housing made from high-strength cast iron or welded steel; gears are case-hardened and ground to ISO 1328 Grade 6 accuracy for durability.
Reliable Lubrication System: Integrated forced circulation oil system ensures constant lubrication and cooling, extending gear and bearing life.
Easy Installation & Maintenance: Horizontal foot-mounted design with standard shaft configurations simplifies alignment and replacement.
Proven in Harsh Environments: Suitable for dusty, high-temperature, and continuous-duty conditions common in ball mill installations.

Frequently Asked Questions (FAQ)
Q: What is the maximum input speed for the MBY710 gearbox?
A: The typical maximum input speed is 1500 rpm. For higher speeds, please consult our engineering team for customization.Q: Can the ratio be adjusted after installation?
A: No, the gearbox has fixed gear sets. However, we offer multiple ratio options within the 8.0–11.2 range. Please specify your required ratio at the time of order.Q: What type of oil should be used?
A: We recommend mineral-based EP gear oils with viscosity ISO VG 320 to 460, depending on ambient temperature. A lubrication specification sheet is provided with each unit.Q: Is the gearbox suitable for reversed rotation?
A: Yes, the design supports bidirectional rotation, but the forced lubrication system must be verified for the intended direction. Please inform us of your application.Q: How does the noise level compare to standard helical gearboxes?
A: The helical-bevel design typically reduces noise by 5–10 dB(A) compared to pure bevel gearboxes, thanks to the helical stage absorbing vibrations.Q: What is the typical lead time?
A: For standard models (common ratios), lead time is 30–45 days. Custom configurations may require 60–90 days. We can expedite upon request.Q: Do you provide installation and commissioning support?
A: Yes, we offer remote technical support and optional on-site commissioning assistance (additional charges apply). Detailed installation manuals are included.Q: Can the gearbox be used with other types of mills (e.g., rod mills, SAG mills)?
A: While primarily designed for ball mills, the MBY710 can be adapted for similar rotary applications with appropriate torque and speed verification. Contact our sales team for a feasibility check.
