For sale is an industrial-grade Beloit Jones DD 4000 42-Inch Double Disc Pulp Refiner, built under Model Number 4342N and Serial Number D-2691. Renowned across the pulp and paper industry for exceptional mechanical reliability, the DD 4000 line utilizes a positive-action electromechanical plate positioning system to maintain flat, accurate, and stable tolerances for continuous stock treatment.
This unit was decommissioned from an active paper mill's stock preparation department and is highly suitable for large-capacity fiber development across chemical pulps, board, packaging, or recycled fiber lines.
Technical Specifications
• Manufacturer: Beloit Jones (Legacy platform supported by GL&V / Valmet)
• Model Line: DD 4000 Series
• Model Number: 4342N
• Serial Number: D-2691
• Nominal Disc Size: 42 Inches
• Piping Design: Two-pipe Duoflo configuration capability (Internal flow splitting eliminates the need to disconnect stock lines during routine plate replacement or inspection).
• Estimated Base Shipping Weight: ~19,000–21,000 lbs (Varies slightly by final component casting).
• Core Application: Fibrillation, fiber length treatment, tensile strength development, and drainage control.
Features & Operational Benefits
• Electromechanical Positioning System: Highly dependable positive-action gearing provides consistent uniform fiber processing over long production runs.
• Hinged End Housing: The outer housing door is cleanly hinged, offering immediate, unobstructed access to internal refining cavities for quick plate changes.
• Heavy Stainless Lining: Built to withstand demanding mill chemical environments, standard configurations feature durable corrosion-resistant fluid contacts.
• Unrivaled Aftermarket Support: Because the Beloit DD 4000 footprint remains a global industry standard, aftermarket segmented plates, packing boxes, and replacement seals are readily available at low operating costs.
Condition & Logistics
• Condition: Used. Salvaged from a closed or upgraded paper mill stock prep plant. The external casting, horizontal shaft assembly, adjusting linkages, and hinged door assembly are structurally sound. Prospective buyers should check internal plate layouts before custom commissioning.
• Shipping & Freight: Freight Pickup Only. The buyer assumes all liability for hiring a certified industrial rigging service, crane loading, and securing a heavy-haul flatbed freight carrier.
