Keeping the “Paper Valley” Moving
The Reality of Recycled Fiber Processing
The Netherlands is a global leader in paper recycling, with hubs in **Eerbeek**, **Renkum**, and **Roermond** processing millions of tons of Recovered Paper (RCP) annually. This efficiency relies heavily on a complex network of material handling equipment: chain conveyors moving heavy bales of OCC (Old Corrugated Containers), screw conveyors feeding pulpers, and vibrating screens separating contaminants.
The operating conditions are deceptively harsh. Drive shafts in the “Wet End” and stock preparation zones face a dual threat: **High-Frequency Vibration** from screening equipment and **Corrosive Humidity** from the pulping process. Standard industrial shafts often suffer from spline fretting due to the micro-movements caused by screen vibration, or seal failure due to the ingress of acidic paper sludge. A failure in the main feed conveyor can starve the entire mill, disrupting the continuous production mandated by Dutch energy efficiency covenants (MJA3).
The Ever-Power “Fiber-Drive” Solution
Ever-Power has engineered two distinct series for this sector: the **Screen-Master™** for vibrating equipment and the **Convey-Pro™** for bulk material handling. The Screen-Master shafts feature a specialized “Long-Travel” spline coated with Rilsan (Polyamide 11) to dampen vibration and prevent metal-on-metal fretting.
For the Convey-Pro series, we prioritize sealing and torque density. Using a triple-lip Viton sealing system protected by a metal slinger, these shafts are impervious to the wet, sticky pulp environment. We utilize 42CrMo4 forged yokes to handle the “Start-Stop” shock loads common in bale handling. This robust design philosophy aligns with **NEN-EN 13001** and ISO 14001 sustainability goals, offering a longer lifecycle and reduced scrap generation compared to standard OEM replacements.
Technology Tailored for Pulp & Paper
Vibra-Shield™ Splines
Composite coated splines with optimized clearance to absorb high-frequency vibrations (5G+) from sorting screens without seizing.
Acid-Proof Coating
C5-M Marine grade epoxy paint system protects the tube and yokes from corrosion caused by recycled paper sludge and chemicals.
Aqua-Seal™ Technology
Multi-labyrinth seals with external stainless steel flingers to physically repel water jets and wet pulp during washdown.

The Power Core: Gearbox Integration
In a recycling plant, the drive shaft is the fuse between the motor and the load. But a reliable system requires a robust gearbox. For chain conveyors and pulpers, the starting torque can be 200% of the nominal load. We recommend pairing our **Convey-Pro Shafts** with **Ever-Power Heavy Duty Industrial Gearboxes** (Helical-Bevel or Parallel Shaft).
Our gearboxes feature reinforced output shafts and oversized bearings to handle the radial loads generated by the cardan shaft during high-torque startup. For the Dutch market, we offer “Drop-in Replacement” services for legacy gearboxes from **SEW**, **Flender**, or **Nord**, ensuring seamless integration with your existing conveyor setup.

Мнение экспертов: Часто задаваемые вопросы для голландских инженеров-мельничников
How can I prevent spline fretting on vibrating screen drive shafts?
Spline fretting is caused by the constant high-frequency micro-movements of the screen. We recommend using Ever-Power shafts with **Rilsan (Nylon 11) Coated Splines**. This dampens the vibration and provides a low-friction glide surface, significantly reducing metal fatigue and extending spline life.
What is the delivery time for a replacement conveyor shaft to Eerbeek?
We utilize a dedicated logistics channel for the EU paper industry. For standard DIN sizes, we can ship within 3-4 weeks. For urgent breakdowns in Eerbeek or Renkum, we offer an **Air-Freight Rapid Response** service, delivering custom shafts in as little as 6-8 weeks from drawing approval.
How do you protect the universal joints from wet pulp and acidic water?
Standard seals fail in the wet end. Our **Aqua-Seal™** system uses a triple-lip Viton seal protected by a stainless steel slinger. This design physically sheds water and pulp fibers, preventing ingress. Additionally, our shafts are painted with C5-M marine-grade epoxy to resist acidic corrosion.
Are your shafts compatible with Dutch environmental and safety standards?
Yes. Our shafts are designed with a Safety Factor >2.0, complying with **NEN-EN 13001** and the **Machinery Directive 2006/42/EC**. We also offer biodegradable grease options for mills with strict ISO 14001 environmental management systems.
