A more sustainable and profitable process

Benefits

Fiber processing is a critical part of your production line and directly determines the quality of the finished product.

It all begins with your furnish and the perfect processing for your fiber requirements. Kadant applications engineers work closely with your team to deliver the best systems to meet those needs with profitable and sustainable results.

We start with the most efficient material handling and a holistic, end-to-end fiber processing solution to get you running, and keep you running.

The grapple hoist effectively removes waste material from the pulper junk tower. Constructed to provide superior performance and long service life, the grapple features individually driven tines and a rugged Hoist for optimum adaptation to handling a variety of materials.

Benefits

Hydrapulpers are designed for specific applications and are based upon furnish, capacity, and operational needs. Our rugged and reliable units are installed in over 8,800 locations across the globe and are proven in a variety of applications and on a wide range of furnishes.

Benefits

The Hydrapulper DR pulper with the Wash Tower, Trashwell, Grapple Hoist, Vortech® Rotor, and Maximizer® Extraction Plate.

The Ragger is designed to remove trash and bailing wire that results from slushing secondary fiber furnishes. It makes quick work of snagging sheet plastic, rags, wet strength paper, and other light trash normally encountered in waste paper furnish.

Benefits

Used to chop the rag rope into shorter sections for easier disposal, this unit features a double-cylinder guillotine design with replaceable hardened steel knife blade and anvil. The hydraulic system includes a 15 HP motor and pump capable of developing 3,000 PSI pressure.

Benefits

An integral part of the Hydraflow Continuous Detrashing System, this high-pressure unit efficiently moves highly contaminated furnish onward to the detrasher for further processing. The pump’s small footprint is perfect for installation into tight locations.

Benefits

The rugged heart of HydraFlow Continuous Detrashing System is this durable detrasher, capable of producing a constant output of low-density, light-weight rejects.

It works with the Hydraflow Trash Pump, alongside traditional continuous pulpers, to increase pulp yield, prevent water waste, and protect downstream equipment.

Benefits

Hydrapurge Detrashers are designed to extract the stock from a pulper to entrap and concentrate contaminants. The stock is passed through the detrashers extraction plate and then sent forward for further processing.

Heavy and light contaminants are retained, washed, and dumped. They are available in several sizes and styles to match the needs of your pulping system.

Benefits

This non-vibrating, low attrition tailing screen removes coarse debris and recovers water from reject loop. This rugged workhorse maximizes stock recovery and dewatering of light rejects and is excellent for both batch and continuous operation.

Benefits

A free vortex separator designed for efficient removal of contaminants from all types of applications including OCC coarse screen, refiner, and deflaking protection in a broke system.

Available in a wide range of sizes and configurations with a low maintenance, non-plugging design for continuous or intermittent operation.

Benefits

Available in a wide range of sizes and configurations with a low maintenance, non-plugging design for continuous or intermittent operation.

Benefits

Fiber processing mastered, end-to-end and in-between. Kadant designs and supplies complete systems and efficient upgrades based upon the unique needs and challenges of your individual applications. This includes enabling the expert transfer, handling, and storage of your valuable fiber.

The 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.

Benefits

The 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.

Benefits

The slotted drum screen is a non-vibrating, low attrition tailing screen that removes debris normally found in the coarse screening loop of most fiber recycling mills.

Ideally suited for processing rejects from a Kadant Float Purger™ stock cleaning system or anywhere a non-pressurized tailing screen device is used.

Benefits

The XCEL NT removes granular debris, grit, glass, sand, pins, staples, gravel, metal, dirt, abrasives, and other small heavy objects while saving you power.

Benefits

The 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.

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.

Benefits

The FiberNET utilizes an enclosed drum-style rotor, which eliminates stringing issues associated with screening stock having high debris levels. The screen cylinder incorporates two cylinder sections which can be optimized separately for open area, slot size and profile angle.

Small slots are used for system efficiency, and fiber savings are realized by reducing long fiber loss. By improving the screening system yield, the FiberNET provides substantial savings to the mill by reducing furnish and landfill costs.

Benefits

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 fiber.

Benefits

The latest reverse cleaning technology to remove lightweight debris from all types of pulp and paper stock. Delivering extremely high cleanliness standards for the removal of wax, styrofoam, hot melt glues, latex, grease and other low-density materials.

Benefits

The Kadant Direct Discharge Disk filter is optimal for stock thickening and water return/ channeling, removing water from pulp slurry.

The disk filter’s main advantage over other dewatering equipment is that it retains most of the fibers. Very clear filtrate means that the water can be returned up-front in the previous steps of the process without carrying fibers that have already gone through the process.

Benefits

The grapple hoist removes the large heavy contaminants from the Trashwell and Wash Tower.

The cantilevered drum screen provides dependable dewatering of pulper rejects for greater savings of water and disposal cost.

The liquid cyclone cleaner removes high-density rejects seen here, such as staples, and ensures rejects are fiber free.

The Kadant SaveMaxx screw compactor is used for thickening light rejects, such as plastics, in recycled paper production. It dewaters rejects from the detrashing and coarse screen drum screens.

Benefits

The slotted drum screen is excellent for the removal of styrofoam, one of the most abrasive contaminants found in recycling furnish.

This type of debris consists of sand, grit, and other coarse materials that not only effect sheet quality, but also quickly degrade downstream equipment such as screens or even paper machine components.

Fine rejects and stickies rejected from the high yield clean pulp fiber stream.

Kadant’s array of low density cleaner options are all design to remove the flexible, sometimes even liquid contaminants that pass through screens only to appear in the final sheet or to remain in the mill’s water system.
