As a global leader in the screening of pulp stock, Kadant offers a full range of options for knotter, coarse, fine, or machine screening. Robust and cost-effective solutions for wastepaper recycling, deinking, or virgin fiber processing, our screens are the industry standard for performance and innovation. Perfect for broke, approach flow and fractionation systems, fines recovery, and aggressive washing operations.
Kadant's Ultra-V vertical pressure screen line features proven innovations created especially for today’s competitive pulp and paper industry. As the world’s most experienced screen manufacturer, we developed the Ultra-V with our patented bottom-fed, up-flow technology to provide unsurpassed performance and reliability in virgin fiber, secondary fiber, stock preparation, and broke systems around the world.
The BoosTEK Performance Pack revolutionizes fiber processing in OCC recycling, stock preparation, and pulp mills. Designed for fine screening systems, BoosTEK utilizes system pressure to amplify the breakdown of stock mats that form on, and ultimately block, the screen cylinder. This proprietary technology improves the performance of the screen resulting in lower energy consumption, increased capacity, improved contaminant collection, and a higher yield of clean pulp fiber.
This robust unit concentrates plastics and other low density contaminates, completing the defibering of accept material. It is usually used in the coarse screening loop of any furnish that is heavily contaminated and not fully defibered. Gentle on debris, this energy efficient, low maintenance system removes more than 90% of light rejects while trapping heavy debris as well – both virtually fiber free.
Pressurized screens for knotter, fine, coarse, and machine screening. Radiscreen applications feature high availability, low power demand, long lifetime, as well as flexible and compact installations. These systems feature the highest hydraulic capacity on the market and are used for all stock types and applications.
The Periscreen-M machine screen is a high-capacity machine screen for all stock types and applications. The design is optimized to maximize efficiency and flow while serving as a protection screen, effectively removing remaining impurities and deflocculating the stock prior to entering the headbox.
The Raditrim series comprises a secondary knotter screen and tailing fine screen. The Raditrim-K is an efficient, totally enclosed secondary knotter screen for high yield with low energy consumption. The Raditrim-F is a completely enclosed tailing fine screen combining shive separation and thickening with effective fiber recovery.
The Kadant screen cylinder line offers a variety of profiled, drilled, and wedgewire designs manufactured for high performance and durability for pulp and paper mill applications. Our broad selection of cylinder profiles and open areas allows for greater process flexibility, depending on the specific process and actual operating conditions. Hole and slot sizes start at 0.004” (0.10 mm) and each cylinder is matched to the application. The pitch, or slot spacing pattern, typically ranges from four to ten slots per inch.
Kadant offers a wide selection of screen rotors to meet the exact needs of your stock preparation. Multiple adjustable rotors are available – standard foils, low pulse, low powered, and non-stringing – all built to exacting standards with durability and efficiency in mind. The correct rotor, when mated with the proper screen cylinder option, provides a high quality pulp with proven screen performance.
The ScreenONE is a multi-stage fine screening system in a single unit. Featuring patented ID-3TM technology in a 3-stage design, it delivers cost effective, high-efficiency screening. ScreenONE is capable of replacing up to five rotating machines in a single system, thus reducing installation costs, power consumption, and maintenance costs. The unique ID-3 technology improves system yield thereby reducing landfill and furnish costs.
Our unique Inward-Flo™ design provides the superior efficiencies of slotted screens to meet the high demands of secondary fiber applications. Perfect for the removal of stickies, drinking, virgin pulp and paper machine approach flow applications.
Designed to provide improved yield by reducing fiber loss, the FiberNET is used primarily as the final stage of screening in a screen system. To capture this fiber that is typically lost, the FiberNET incorporates two screening zones with ID-3™ technology for maximum fiber recovery. The ID-3 cylinder and rotor work together to increase the active area of the screen cylinder surface, creating more consistent flow through the screen cylinder.
