Summary of Expertise: Listed with other top experts in: 
The paper clay coating process covers the area from unloading chemicals from a rail car or a trailer truck to storage tanks and tote bins for minor additives and dispersing the clay with starch or latex binders to a solids content suitable for the application process - pumping and filtering the coating color that is then delivered to the Run Tank System preceeding the Paper Coating Process. Expert has many years of experience with this process.

The Run Tank System consists of a Run Tank, preferably of Conical Shape with Double Wall for Cooling or Heating. The Run Tank System also contains filters and dearators to avoid scratching and skip coating during the process.

The paper coating process can vary depending on the grade of coated paper that is to be made. E.g. LWC paper (Light Weight Coated) is primarily done on a MSP (Metered Size Press) with the capacity to apply light coat weights to both sides of the sheet at high speeds. Coated Fine Paper can also be processed in a MSP, but it is more common to use Blade Coater for these grades as higher coatweights may be applied and better paper qualities such as Smoothness, Brightness, Opacity, etc. can be more easily produced. Rod Coaters can also be used for these grades, but will cause slower operating speeds and film split that will reduce quality. Therefore, Rod Coaters are used more in double or triple coating of Board Grades (SBS/SUS) that are produced at lower machine speeds. Expert can help with understanding of the paper coating process and troubleshoot any problems

Paper Drying can be accomplished with four different technologies, which Expert has indepth understanding of. The Steam Dryer Can still being the most ecconomcal after more than 100 years of paper making. Air Dryers with high temperature and high velocity are common, but mainly for Tissue production and Clay or Starch Coated grades. Gas IR is frequently used for drying of Clay Coated grades, but cannot be used to dry an uncoated base sheet because of a radiation wave length unsuitable for penetration into a fiber web. Electric IR, on the other hand, has a shorter wave length that is excellent not only for drying Clay Coatings and Starch, but also works very well on an uncoated base sheet. The efficiecy of electric IR is nearly 4 x that of Gas IR

Paper Equipment is a rather broad term and can actually start at the pulper and end at the Winder and/or a Sheeter. Expert has "Engineered" Equipment covering it all.

Paper Industry is also a Broad Term for the processes used to make paper - from the Kamyr Digester to the Shipping Dock of the Finishing Room. Expert has had a finger on design of all mechanical equipment used in the process.

Paper Machine Design differs depending on what grade is to be made. For Tissue and Machine Glazed Grades a so called Yankee Machine is used where the forming of the sheet is done on a straight forward Fourdrinier Machine or on a Crescent Former. The Yankee name comes from the large diameter dryer used to dry and/or creep the paper. Expert rebuilt several tissue machines in Scandinavia for higher speed to increase prodution.

Other types paper machines are Cylinder Machines and Fourdrinier Machines or combinations of both used for production from LWC to SBS and SUS (Solid Bleached Sulfate/Solid Unbleached Sulfate). Expert's personal experience is with Tissue Machines and Fourdrinier Machines for production of Fine Paper and SBS/SUS + expertise in all types of Coating Application.

Papermaking is term describing the "art of making paper" When designing paper mill machinery it is important to also have good knowledge of the physical properties of paper and how the different paper grades need to be treated in order to have the appropriate properties for the grade. This is mainly done in the refining process (disc refiners) + the wet-end chemistry and of course also by the surface treatment. (See Coating)


The most important asset an engineer can have for "Engineering" in the field of recycled paper manufacturing is the "papermaking" experience plus the knowledge of how to best remove impurities from the recycled paper. There is much equipment available in the marketplace today. Some work better than others and the knowledge of what works and what not can save a client much money and headaches.

Wet-end paper operation varies with grade. Today mostly Fourdriniers are used for sheet formation, but there are many versions like with e.g. Dilution Head Box Profiling, combinations of Forming Equipment such as the Manchester Former, the BRDA formers, Cylinder Formers + Fourdriniers, etc. Single ply forming on a Fourdrinier is pretty straight forward. The Engineering Talent becomes challenged when serveral Formers + Fourdriniers are combined to form a thicker board of e.g. SUS from Recycled Paper with 3 to 4 layers. Expert's experience in this field is good.
