The Pulp and Paper industry has its own unique requirements when it comes to mixing.  They need a high-quality consistent product in order to maximize the time between shutdowns and prevent any unscheduled downtime. In addition to these requirements, the mills also need to meet rigorous environmental controls and energy-saving solutions. A high-quality static mixer is a solution for the pulp and paper industry.

The Process Applications in a Pulp & Paper Mill

The pulp and paper mill applications include manufacturing paper from a variety of textiles, which include wood and cellulosic materials.  The major pulping process in the mills consists of mechanical, semi-chemical, sulfite, sulfate, and defibrated.  Applications within the pulp mill are recovery areas, coating kitchens, and water treatments.

Mixing is a requirement in all areas of a pulp mill, which is why static mixers are a solution for many of the applications’ problems.

Specific Applications within the pulp and paper mill:  

•         High-Density Towers
•          Bleaching Towers
•          Press Pits
•          Stock Chests (Dilution, Storage, Rejects, Broke, Blend, Dump, Machine, Equalizing, Latency)
•          Blow Tanks
•          Recovery Operations (Black Liquor, Green Liquor, Dregs, Smelt, Tall Oil)
•          Water Treatment
•          Coatings (Starch Slurry, Clay Storage, Dye, TiO2, CaCO3, Dye, Polymer)

Issues Pulp & Paper Mills Have

Consistency measurement is one of the most difficult variables to measure and control within the pulp and paper mills.  As the growth in the continuous process technology work has been done to improve the uniformity within mixing while decreasing the energy needed.

Triple Action Static Mixer Delivers with its Unique Design

The Komax Triple Action Static Mixer’s unique design is able to provide the highest level of mixing when compared to traditional motionless static mixers.  The mixing elements provide two-by-two division, cross-current/impingement mixing, and back mixing. 

The Komax Triple Action Mixer creates backmixing which generates the high shear that is required to separate pulp fibers.  Fluidization of the pulp also occurs, allowing chemical contact that decreases chemical usage.

The triple-action mixing also provides controlled consistency for stock blending applications.  Whether it is mixing different consistent stock streams or diluting stock with water, the low-pressure drop design results in a uniform reading from the transmitter.

All of Komax’s static mixer designs, PVC Static Mixer, Kynar Lined Static Mixers, Fiber Glass Static Mixer, Stainless Steel Static Mixer, Sanitary Static Mixer, contain the triple action static mixing elements.

Providing Robust Solutions

Pulp and Paper mills have found by installing Komax products is an economical solution to their mill’s problems.  Because the Komax static mixers can handle high consistencies, like slurries, it ensures the industry better results in consistency and homogenous mixing throughout the entire process conditions.

Komax is leading the industry in static mixing technology, which is why their solutions are in over 100,00 installations worldwide.  Pulp manufacturing has many processes that require advanced technology in addition to static mixers, Komax has solutions for steam heaters.  Contact them to help provide application solutions for your mills’ needs today.
