      Pulping

      The suitable technology for each resource

      Fibers from virgin pulp, recovered paper or paper machine broke are pulped with water to form a suspension in the  “Pulping” process step. An optimal pulping technology can be selected, depending on the type of furnish, production output and the contaminant included in the furnish. Pulping systems for recovered paper not only break down the fiber material, but also remove large non-recyclable components (rejects). It is, therefore, important to balance the main pulping parameters such as stock consistency, temperature, mechanical attrition, dwell time and chemical additives so that trash components are not broken down unnecessarily and, thus, made more difficult to screen later in the process. Pulping of recovered paper also has to consider the various parameters for downstream ink removal if used for graphical paper products.
      IntensaDrum Duo

      IntensaDrum Duo is a two-piece drum pulper for stock preparation system with high production. The machine design is based on our succesfull IntensaDrum and implements the long experience of Voith drum pulpers. Higher than standard pulping consistency and efficient screening process are key points adding to a long list of benefits with the IntensaDrum technology. In addition, modular components transfer the IntensaDrum Duo technology and reliability to a new level.

      IntensaPump

      Highly contaminated stock flows in the pulping system for recovered paper can only be pumped reliably and largely free of blockages using a special pump. Whether in LC or HC system, IntensaPump pumps the critical contaminants to the next machine very reliably in both systems, BluePulp LC and BluePulp HC. Featuring large nozzle diameters and a free-flow impeller, IntensaPump is designed for plug-free pumping of stock flows with a high proportion of contaminants. The impeller has a long service life thanks to its hard facing. A frequency converter offers the possibility for optimized pump speed and reduced energy consumption for intermittent pumping operation.

      Cleaning

      Removal of contaminants with minimal fiber loss

      Cleaning systems are used to remove coarse or fine heavy and lightweight contaminants as well as entrained air. This provides a clean fiber material but also reduces wear and tear in the downstream equipment. The cleaners are used for recovered paper stock systems, approach flow systems, and stock preparation systems with virgin fibers.

      To minimize fiber loss, the rejects have to be processed in subsequent cleaner stages. There are two or three cleaner stages in Voith's recovered paper systems. In the approach flow system, no more than four stages are required.

      InduraClean

      InduraClean is a modular system for heavyweight cleaning that consists of a redesigned cleaner bank and various cleaners that are perfectly matched to one another. Depending on process requirements, the system can focus on production volume, energy consumption, or separation efficiency.

      InduraHiClean

      InduraHiClean is a high-consistency cleaner that removes abrasive contaminants directly after the pulper. With the use of IDH cleaners, the wear of machines located downstream in the process – such as screens or deflakers – can be minimized.

      Product Details
      Lower Maintenance Cost

      Screening / Fractionation

      Removal of undesirable contaminants

      Immediately before the stock suspension enters the headbox, pressure screens are installed both in the main flow and in the ModuleJet dilution stream if provided. Since these screens provide a last barrier before the paper machine to prevent damage by foreign bodies, the connection between screen and headbox must be directly linked and completely closed. Screening can also play a key role in paper machine broke treatment for removing trash accidentally introduced in the broke.
      IntegraScreen

      The flow-optimized machine housing results in constant flow and pressure conditions around the basket. Together with the use of the experienced Voith rotors and screening baskets, a high sticky reduction is achieved.

      Flotation

      Improve optical cleanliness

      The primary goal of flotation deinking is the selective removal of printing ink, stickies and hydrophobic impurities in general from the stock suspension, thus improving the brightness and optical appearance of the product. Fillers and coating particles can also be removed efficiently with flotation.

      Selectivity is important for retaining useful material such as fibers in the accepts. The selectivity criteria is the wettability of the particle surfaces. The more hydrophobic the particle surface, the better it adheres to an air bubble and the better the chance of its removal.

      InjectaCell

      The InjectaCell flotation system removes contaminants from the stock suspension with minimal fiber loss. Due to the two-stage design, the flotation process is extremely efficient.

      Product Details

      Washing / Thickening / Dewatering

      The purpose of washing is to remove undesirable particles smaller than 30 µm from the fiber suspension through a separation process according to the filtration principle. In contrast to thickening, which mainly removes water, washing separates solids from solids. At the same time, however, dissolved and colloidal contaminants are also removed with the filtrate.

      Thickening is important for increasing the stock consistency as required for further processing, minimizing storage volumes and for water loop separation. With the dewatering process, the stock consistency is increased from about 5 to 30% or more to prepare for the next process stage and for complete water loop separation.

      Dispersion / Bleaching

      Reduce unwanted contaminants and improve optical characteristics

      Disperging is used in recovered fiber systems for reducing unwanted contaminants to a size not interfering with downstream processing. Disperging also has the task of dislodging and reducing residual ink particles from the recovered fibers. This is a precondition for efficient deinking in flotation cells. In recovered fiber systems for brown papers (OCC), disperging must also improves fiber strength  in addition to reducing unwanted contaminants. In bleaching systems, dispergers are used for intense mixing of the bleaching agents with the fibers.

      Bleaching improves the optical characteristics of the stock. The brightness is increased with the penetration of chemical additives by bleaching the fibers and colour stripping as well as moving the colour spectrum.

      Refining / Deflaking

      Improved stock quality through effective fiber treatment

      Voith refiners increase the specific fiber surface of each single fiber resulting in improved stock quality for the paper machine.
      Fiber treatment includes the most important actuating elements in terms of disintegration and surface treatment of each single fiber. Deflaking breaks up fiber bundles to prevent sheet brakes, thereby directly improving the paper machine runability. Refining increases the specific fiber surface of each single fiber resulting in higher strength potential due to fiber-fiber bonding and higher chemical absorption capacity.

      Voith is the market leader for compact disk applications in the field of fiber treatment. Disk applications provide very good accessibility, enabling a fast and secure filling change with low downtimes.
