Doctoring? Roll cleaning? Scraping? Flaking? Continuous belt cleaning? These are terms for a similar process used differently depending on the industry, but the product’s purpose is the same–to clean or remove contaminants from a roll surface. A doctor blade, roll cleaning blade, scraper blade, or flaker blade is any material in stick form that is run against a roll and is used to keep the roll clean. Materials can be just about anything like composite, metal, or plastic.

  • How do I get the most out of my doctor or roll cleaning blades?

    1. Make inspecting blade and holder conditions a part of your maintenance routine.
    2. Change blades any time the machine is down for cleaning.
    3. Change the blade immediately any time there may be damage to the blade.
    4. Use a blade change indicator at the beginning of each blade change.
    5. Keep an inventory of commonly used blades to reduce downtime.
  • What happens when a doctor or roll cleaning blade wears?

    As a blade wears into the roll, the area of the blade contact increases. Even though loading pressure remains unchanged, actual transmitted blade pressure decreases due to the surface contact area getting larger. Increasing loading pressure with a worn blade will greatly reduce the efficiency of the system and may allow material to pass under the blade and wrap the roll due to the additional deflection of the blade.

  • How do I know if oscillating a doctoring or roll cleaning system is right for my process?

    If your process could benefit from better roll cleaning action, extended blade and roll life, increased sheet quality, and less chatter and dwell of the roll cleaning structure, an oscillating doctor system could be a significant advantage for your application.  

  • Do I need to use Kadant doctor or roll cleaning blades in a Kadant doctor or roll cleaning holder?

    Yes. Kadant has a genuine parts program backed by our technical blade experts. The Kadant genuine parts program focuses on employee safety, operating performance, and return on investment. Using Kadant blades is the only way to ensure the highest product quality and that integrity is maintained when using Kadant doctor holders.

Filtration products, such as pressure filters and water resource recovery strainers, are used to remove contaminates from liquid in process industries. A filtration system will contain a filter media which is used to separate unwanted particles from the substance being filtered. The filtration process can be intermittent or continuous providing high cleaning efficiency and easy maintenance.  

To maximize performance, filtration systems are chosen and designed for the application. Common applications include fresh water, process water recycling, dyes and additives, mechanical seal protection, chemicals, DAF filtrate, clearleg save-all water, overflow cylinder vat water, vacuum pump seal water, felt hair removal from press section, fiber recovery from u-drains, solids separation, thickening, fiber scalping, removal of sand from rivers and lakes, cooling towers, pump protection, steel mill water recycling, and spray nozzle protection.

  • Water Resource Recovery Strainers

  • Filter Media

  • Auto Strainer

  • Fine Filtration Systems

  • Multiple-Barrel Pressure Filter

  • V-Force Solids Separation System


  • Why do pressure liquid filters clog?

    There are a couple common reasons why pressure liquid filters clog quickly. First, the process may be unstable and the solids loading becomes high. Alternatively, the process may have changed, or the filtration equipment isn’t installed in the correct place for the application.

  • Our roll temperature is very hot, are there suitable roll cleaning blades available?

    Yes. There are roll cleaning blade materials available with high temperature resins capable of being used in temperatures as high as 570°F (299°C). 

  • Will the roll cleaning blade damage the roll material?

    Choosing the right type of fibers and resin is key when selecting the roll cleaning blade.  Usually, carbon fiber is used as a tough, wear resistant material but will be gentle and ensure that the roll surface roughness is maintained. Additionally, there are a series of roll conditioning pads available with the EzKleen™ V roll cleaner assembly that can further enhance roll conditioning.

  • Is there a benefit to oscillating the VeriLite roll cleaner assembly?

    Yes. Oscillation can improve the roll cleaning process. The movement of the blade tip provides a secondary cleaning action and ensures that debris does not embed into the blade tip, which could groove or score the roll surface.
