Customized Solutions
Boneng HB‑series heavy‑duty helical / bevel‑helical gearboxes are adopted together with drive motors, featuring compact layout, high load‑capacity and good shock resistance. This solution fits continuous refining conditions with stable and reliable operation.
Technical Highlights
Compact Structure & Flexible Installation
- Multiple output‑shaft versions save installation space and adapt to different machine layouts.
Smooth Operation & Long Service Life
- Large‑module gears plus reinforced‑bearing configuration deliver low vibration & noise, long maintenance intervals and effectively cut operating costs.
Proven Industry Applications
- Widely applied in papermaking pulp‑preparation systems, compatible with mainstream disc‑refiner models on the market.
Application Cases
Filter Press
Customer Pain Points
Filter presses operate long‑term under heavy loads, shock and high‑humidity corrosive conditions. Conventional transmissions suffer insufficient torque and seal failure, causing frequent shutdowns.
Boneng Solution
Adopt H/B‑series heavy‑duty reducers to deliver high‑torque output and reliable sealing protection.
Project Results
- Equipment continuous‑operation rate raised above 99.5 %
- Unplanned shutdowns reduced by 45 %
- Maintenance costs cut by 28 %
Pulp‑Section Screw Press
Customer Pain Points
Screw presses require high torque and precise speed control. Conventional reducers feature large backlash and insufficient accuracy, hurting pulp dewatering efficiency and fiber quality.
Boneng Solution
Adopt P‑series planetary reducers to realise high‑load modular transmission.
Project Results
- Pulp‑processing efficiency improved by 18 %
- Stable improvement of finished‑fiber quality
- Energy consumption reduced by 12‑15 %
Rewinder
Customer Pain Points
During rewinding, unstable lifting/lowering of press roll and linear‑pressure control cause large tension fluctuations, easily resulting in wrinkles and paper breaks, hurting finished‑product yield and production speed.
Boneng Solution
Adopt J‑series screw jacks (synchronous left‑right layout) to realise precise lifting/lowering of press roll and stable linear‑pressure control, ensuring tight‑core loose‑outer rolls and neat roll end‑faces.
Project Results
- Greatly improved synchronism of press‑roll lifting‑lowering and linear‑pressure stability; finished‑product yield raised above 98 %
- Production speed increased by 15 %
- Reject rate reduced by 30 %
