Keeping the “Paper Valley” Moving<\/h2>\n
\n
\n

The Reality of Recycled Fiber Processing<\/h3>\n

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.<\/p>\n

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).<\/p>\n<\/div>\n

\n

The Ever-Power “Fiber-Drive” Solution<\/h3>\n

Ever-Power has engineered two distinct series for this sector: the **Screen-Master\u2122** for vibrating equipment and the **Convey-Pro\u2122** 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.<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

The Power Core: Gearbox Integration<\/h3>\n

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).<\/p>\n

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.<\/p>\n

Case Study: Renkum Newsprint Mill<\/span><\/p>\n

Solving “Wet End” Vibration in Reject Screening<\/h3>\n

The Challenge:<\/strong> A major newsprint mill in Renkum was facing chronic failure of drive shafts on their coarse reject screens. The high-frequency vibration (5.5 G) combined with water ingress caused the spline coating to peel off, leading to metal-on-metal fretting and seizure every 3 months.<\/p>\n

The Ever-Power Solution:<\/strong> We installed the Screen-Master 390 Series<\/em> featuring our “Vibra-Shield” Rilsan coating and a custom labyrinth seal. We also increased the spline overlap length by 20% to better distribute the contact pressure during operation.<\/p>\n

The Impact:<\/strong> The shaft lifespan increased to over 18 months. The vibration transfer to the gearbox was reduced, lowering noise levels and extending the gearbox bearing life. The mill saved approximately \u20ac45,000<\/strong> annually in maintenance costs.<\/p>\n<\/div>\n

Expert Insights: FAQ for Dutch Mill Engineers<\/h3>\n
\n

How can I prevent spline fretting on vibrating screen drive shafts?<\/h4>\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n

What is the delivery time for a replacement conveyor shaft to Eerbeek?<\/h4>\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n

How do you protect the universal joints from wet pulp and acidic water?<\/h4>\n
\n

Standard seals fail in the wet end. Our **Aqua-Seal\u2122** 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.<\/p>\n<\/div>\n<\/div>\n

\n

Are your shafts compatible with Dutch environmental and safety standards?<\/h4>\n
\n

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.<\/p>\n<\/div>\n<\/div>\n
