Produr, Wear Solutions for the Paper Industry
Pulp production equipment, whether processing wood or recycled fibers, is exposed to continuous wear stresses: abrasion, impacts, erosion, clogging of ducts, and even corrosion.
Whether it involves grinding wood, transporting pulp, or evacuating fibrous by-products, each stage places demands on critical components that are often sensitive to premature wear.
In this humid, loaded and abrasive environment, PRODUR supports you in improving the reliability and extending the service life of your equipment.
Ultimate Performance Against Wear, Heat and Corrosion
PRODUR offers a selection of technical materials meeting the specific requirements of the paper industry: abrasion, impacts, humidity, corrosion, erosion:
- Duraplate® (D31T, Hi-Speed…): overlay plates based on complex carbides, designed for high-abrasion areas while remaining easy to integrate (welding, bending, cutting).
- Creusabro®: high-performance wear resistant steel, particularly effective in cases of wear combined with moderate impacts. It provides longer service life than conventional 400/500 HB steels.
- Durhart® 200: ceramic solution ideal for the internal protection of piping, elbows or hoppers subjected to sliding abrasion.
- Duranox®: stainless steel lining for equipment located in humid or corrosive areas (tank bottoms, screw conveyors, interfaces in saturated environments).
Each material is selected according to the actual stresses to reinforce your installations, limit shutdowns, and extend the service life of your equipment.
Manufacture of Wear Parts for the Paper Industry
PRODUR manufactures, according to your drawings, wear parts adapted to the constraints of the paper and wood industry: grates, scrapers, blades, shells, debarker tiles or hopper liners.
The materials used are defined according to your specifications: abrasion resistant steel, overlay plate, Creusabro®, Duranox®..
Each part is produced in strict compliance with the required tolerances, with rigorous quality control at every stage.
Our commitment: to supply reliable, compliant parts delivered within controlled lead times to ensure the continuity of your operations.
Wear Audit and Reliability Improvement of Your Paper Industry Equipment
Beyond manufacturing, PRODUR supports you in improving the reliability of your critical equipment: piping, conveyors, crushers, classifiers, hoppers, cyclones …
Our teams identify wear-sensitive areas, analyze mechanical and environmental constraints, then propose tailor-made solutions: geometry optimization, addition of liners, selection of higher-performance materials.
When original parts are no longer available or cannot be modified, we perform 3D scanning to ensure accurate reverse engineering, integrating functional improvements and more resistant materials.
This approach extends the service life of your components, reduces unplanned shutdowns and improves production continuity.
We turn your wear challenges into sustainable performance!
CASE STUDY
Replacement of pneumatic piping
In a paper mill, a fine ash transfer line located at ground level showed premature wear. The objective of our intervention: improve installation reliability while respecting space constraints.
PRODUR designed a tailor-made solution with abrasion resistant ceramic components:
- Elbows lined with DURHART® 200,
- Straight sections inDURZALT® 40,
- Adaptation flanges and bimetal pipes as complementary components.
Result: a durable line, resistant to abrasion, and easier to maintain thanks to standardized components.
CASE STUDY
Lining of a duct & an expansion joint
Facing premature wear of a stainless steel expansion joint and duct on a bark feed line, PRODUR proposed a tailor-made lining in DURPLAST® S, an elastomer resistant to impacts and abrasion.
Result: improved durability, parts reused instead of being replaced, and immediate operational gains.
CASE STUDY
Reliability improvement of a bark conveyor
In a paper mill, a bark conveyor was experiencing rapid wear despite the use of 400 HB steel. PRODUR proposed a new solution combining two materials:
- Bottoms and sides in DURAPLATE® D31T,
- Running rails in DURSTEEL® Mn.
This combination allows the abrasion and impact constraints to be precisely targeted.
Result: doubled service life of the rails and a significant reduction in maintenance shutdowns.
CASE STUDY
Reliability improvement of a drying duct
In the wood industry, an insulation panel manufacturer was experiencing corrosion and clogging issues on its fiber drying duct. The existing installation consisted of partial 304L stainless steel and standard S235 plate, heavily stressed by heat, humidity, and aluminum salts.
PRODUR proposed a complete reconstruction in DURANOX® 12, a martensitic stainless steel resistant to corrosion, designed to facilitate the flow of impregnated fibers.
Result: a homogeneous, durable line, optimized from the design stage thanks to 3D scanning.
