Systematic Approach to High Consistency Refining

When addressing high consistency refining, mills need to use a systematic process to achieve the highest optimal outcome. The following steps will aid in achieving optimum process conditions, optimum refiner plate design, improved plate life, increased trial success and refiner optimization and efficiency.

Refining System Optimization — A Simple Six-Step Process

The refiner is a critical piece of equipment in the paper making process. It is the only piece of equipment in the fiber line that is designed to mechanically enhance the properties of the fiber. Unfortunately, refiners are often neglected and inefficiently operated, negatively impacting quality and paper machine performance. What “goes on” inside the refiner has often been referred to as “Black Magic.” Take the “Black Magic” out of refining by applying a simple six-step optimization process. Read more to gain the basic tools for optimizing your refining system.

New information on Diagnosing Refiner Plate Failures

J&L has made further developments on diagnosing refiner plate failure modes in thermo-mechanical pulping. To improve your pulping process, it is essential to correctly diagnose the causes leading to plate failure. Only then is it possible to select the proper design and alloy materials for TMP refiner plates.

Mill Experiences of Evacuating Refiner Plates

Evacuating refiner plates makes it possible to control and alter the temperature and pressure profile prevailing in the refining zone. As a consequence the refining conditions can be optimized for higher refining efficiency. At IMPC 2007, J&L presented the results from several full scale mill trials with emphasis on refining efficiency and pulp quality as well as operational issues.

Mechanical Pulping: Thinking Outside the Box

Have you ever noticed some of the best ideas are realized by talking with your peers. It serves as a great tool for thinking outside the box. We know from experience, such as J&L’s October 2006 Mechanical Pulping Seminar, this is exactly what happens when our customers get together to discuss issues pertinent to their mill.

Let’s All Do “The Wave” with J&L’s New Venturi Pattern for High Consistency Refining

There’s a new game in town and we can’t help but raise our hands to spread the excitement. J&L’s new damless Venturi pattern is designed with “wavy groove bottoms” and “wavy bars” that significantly improve refining efficiency. Depending on the objectives of your mill, Venturi allows you to improve the quality of your fiber output at a given energy input or lower your energy use while maintaining pulp quality.
