ProJet received an order for 2 Power Cleaners (dryer fabric cleaners) from BioPappel, Tres Valles, Mexico for their Paper Machine # 1. The order was received in November 2021 and the value of the order will not be disclosed.
The order confirms the long-term relationship between BioPappel and ProJet. BioPappel has already multiple Cleaners running at Paper Machines at several of the company’s manufacturing sites, such as Tuxtepec, Durango,Veracruz and Tizayuca.
The paper machine at Tres Valles is 7.5 meters wide and runs up to 900m/min. It produces Medium Board (23-33# at 2,500fpm), using 100% OCC. OCC is known for its extreme contamination on the 1st and 2nd Dryer Sections. ProJet’s Power Cleaner is highly effective in maintaining cleanliness and permeability of Dryer Fabrics which is exactly the reason that BioPappel chose ProJet again. The equipment is scheduled to be delivered in March 2022 and installation & start-up in later in 2022.
The Power Cleaner cleans the Dryer Fabrics continuously, 24 hours a day, as long as the machine is running. Older technologies are operated in batch cleaning mode, allowing the dryer fabrics to get dirty first, losing permeability, and then trying to restore that permeability again. This leads to uneven permeability profiles over time, mostly leading to paper quality issues and more broke. The above graph shows the advantage of continuous cleaning, leading to a more stable moisture profile, less broke and longer lifetime of fabrics. Dryer fabric contamination is on the rise due to the increasing use of secondary fibers, recycling of coated broke, increasing use of sheet fillers, an increased use of recycled mill water supplies, and the increased use of process chemicals.
The Power Cleaner uses a single traversing head that cover the fabrics using up to 14 ruby nozzles at a pressure of maximum 500 bar (7,500psi). Air knives and a Venturi-vacuum-system make sure all water and debris is effectively discharged into a save-all and from there, outside the machine. A clean dryer fabric, with consistently high air permeability, delivers important productivity and performance advantages for dryer section applications. The desired end result, of a clean dryer fabric, is a substantial improvement in available dryer capacity. ProJet’s innovative cleaning system is being applied successfully to very low basis weight product as well has heavy weight paper board applications.
Applying a ProJet Cleaning Solution guarantees consistently clean dryer fabrics from beginning to end of usable dryer fabric life. Consistently clean fabrics deliver the following significant manufacturing advantages:
·No chemical cleaning will be required to maintain fabric cleanliness.
·No shutdowns will be required for fabric cleaning. This will provide increased manufacturing productivity and profitability.
·Maintaining consistently high dryer fabric air permeability increases available dryer capacity.
·Better CD moisture profiles will be maintained.
·Sheet curling, caused by uneven drying, will be eliminated.
·Dryer fabric life will be substantially improved.
·Much less contamination will be deposited on dryers, doctor blades, and felt rolls.
ProJet understands that each client application is unique. For that reason, ProJet developed an automated ROI-calculator that will be applied to each application and produced paper grade. By contacting firstname.lastname@example.org or email@example.com ProJet will perform a no-charge ROI calculation of any Forming Fabric, Press Felt or Dryer Fabric application. After inputting the process parameters provided by customers, they will be provided with a ROI-Analysis of each specific application and investment justification.
ProJet is represented by InnovaPaper, Mr. Ian Robertson. Robertson has been assisting the Mexican paper industry for the last 30 years to ‘know the unknown’ and striving to help paper mills gear up and adopt technology driven productions. Robertson’s constant endeavor has been towards establishing and bringing to the doorsteps of Mexican Paper Mills, new and latest technology which has a direct influence on paper quality and machine run ability.
ProJet and InnovaPaper are present on the LATAM Paper Exhibition, to be held in Mexico City from November 10-12, 2021.
