Wood chip transportation screw
Paper mill production processes include debarking, chipping, pulping and washing. This can result in component wear through abrasion, corrosion, pressure and temperature.
Costly plant components such as wood chip transportation screws used in Pulp and Paper mills, are impacted by varying degrees of abrasive wear, depending on the material type and rates of transport.
With over 50 years’ experience in wear protection backed by intensive research and development, Welding Alloys developed a leading range of solutions to protect wood chip transportation screws for Paper mills. From our advanced welding consumables, automated hardfacing and cladding welding machines, to our turn-key Integra services, we have the solution for your Paper mill applications. To provide best in class customer support, our Integra service centres and technical experts are strategically located across the globe in locations that match our markets.
Although our Integra team regularly undertakes projects similar in nature, they approached the project systematically by applying proven Welding Alloys methodologies to determine the most suitable solution. This included data collection through analysis and inspection of different screws, a review of the parts’ records, assessment of the overall working environment and by conducting interviews with the plant operators. During the Covid-19 pandemic, our skilled teams were able to complete the analysis phase with limited access and regularly undertook remote assessments through use of technology, which has become part of our standard offer.
From the initial analysis, the Welding Alloys technical experts determined that screws were experiencing significant wear caused in the main, by high levels of abrasion as a result of the materials and particle dimensions. Our technical team interacted with Welding Alloys peers in two other global regions to discuss the project and to review recent project records where solutions for wood chip transportation screws were developed to deal with similar abrasion challenges.
