The Challenge
A break on a paper machine is enormously costly, so equipment must be kept reliable and repaired fast. Pulp and paper mills combine abrasive stock, corrosive process chemistry, and high-speed rotating equipment running around the clock — pumps and rolls erode, tanks and chests corrode, and bleaching chemicals attack everything in the line.
Stock and process pumps, rolls and cylinders, chests and tanks, screens, and extensive pipework suffer erosion from fibrous stock and fillers and corrosion from bleaching and process chemicals. Downtime on the wet end is measured in lost tonnes.
Belzona erosion- and chemical-resistant coatings and metal repair composites rebuild and protect pulp-and-paper equipment in situ, without hot work. Rumford Industrial Group applies them to extend equipment life and support fast, reliable maintenance.
Belzona Solutions for Pulp & Paper
Solids Handling & Wood Processing Equipment Restoration
De-barkers, hoppers, screw conveyors, conveyor belts, and drive rollers suffer abrasion and wear from continuous wood and pulp processing, requiring metal and rubber repair materials plus positive grip systems that eliminate belt slippage and protect against abrasion and corrosion.
Chipper discs & lumber transfer rollers
- Chipper Disc Repair — Chipper discs suffer impact damage and wear from the pulping process, requiring solvent-free repair composites to rebuild worn disc pockets and maintain chip quality.
- Lumber Transfer Rollers — Drive rollers suffer abrasion and corrosion during lumber transfer, requiring rubber repair materials with positive grip systems to eliminate slippage and restore transfer efficiency.
Pump Repair and Protection
Liquid vacuum pumps and fan pumps suffer cracking and holing from continuous operation, requiring cold-applied paste-grade metal repair composites and coatings that restore original profiles, provide long-term erosion and corrosion resistance, and increase pump efficiency up to 7% on new equipment and 20% on refurbished equipment.
Mechanical Equipment Repair
Shafts and dryer can journals suffer bearing vibration, wear, and lubrication loss, requiring repair materials that reduce start-up friction by trapping and holding lubricating oil, with fast-curing composites for emergency bearing failure repairs.
Evaporator and Heat Exchanger Protection
Tube sheets, flange faces, water boxes, and end covers suffer erosion, corrosion, high-temperature degradation, and chemical attack, requiring high-temperature-resistant repair composites rated up to 150°C (302°F) and immersion-grade protective coatings rated up to 60°C (140°F).
