See Why You Should Participate in TAPPI Standards You too can expand your network and establish yourself as a SME
TAPPI Standards Test Methods are procedures and related practices used in the measurement, evaluation, and description of pulp, paper, packaging, and related products, including raw materials used in their manufacture, use, or in scientific investigations of any such substances. There are more than 240 TAPPI Standards and each has a Standard-Specific Interest Group (SSIG) made up of industry professionals who regularly review and vote on that standard.
All SSIGs require a minimum of 10 members in order to ballot and vote on a draft of a method and many have open ballots. You can join an SSIG at any stage of the process and participate at your convenience.
Now’s a great time to get involved! See what others have said about their participation in Standards and TIPs.
Your time is valuable, and so is your perspective. You may be new to the industry but you bring something new to the industry, too.
- No mandatory meetings to attend
- Minimal time commitment. You can expect to spend 20 minutes to six hours over the course of a Standard’s five-year life cycle
- You are encouraged to participate in multiple SSIGs
Your opinion matters. Different views and perspectives are valued in SSIGs. Neither TAPPI membership nor deep experience is a required to participate in a SSIG. Anyone that uses a TAPPI Standard is familiar with the technical review process or other standards is welcome.
What is required?
- Willingness to grow as an industry influencer, sharing your expertise, knowledge and technical information to help shape the industry’s future
- Inclination to gain an instant network of technically inclined and involved peers
- Curiosity and a thirst for knowledge. There’s no better way to gain a comprehensive understanding of what a test method does, how it works and learn about its practical uses than by being part of a SSIG

TIP 0508-10: An Introduction to Centrifugal Cleaners The purpose of this Technical Information Paper is to introduce the reader to centrifugal cleaners, from basic theory of operation to practical operational issues. Specifically, high density, low consistency forward, and lightweight cleaner types are presented along with their purpose in stock preparation.
Most paper making pulps contain contaminants with either specific gravity and/or surface area which is different from usable fiber. Such contaminants can be separated using centrifugal forces that accentuate such differences. The most suitable equipment for removing these types of contaminants is the centrifugal cleaner; a static device that applies centrifugal force to a pulp slurry to separate fiber bundles (shives), heavy, and light components from the papermaking fibers.
The hydrocyclone is a closed vessel designed to convert the velocity of the feed stock into a spinning motion. The spinning velocity of the stock separates particles heavier than fiber to the wall of the cleaner body and lighter debris to a vortex at the inner portion. In conventional centrifugal cleaners, heavy rejects report to the apex of the cone and lighter particles report to the overflow (or base) of the cone. There are several other configurations that are discussed the text that follows.
Energy consumption in centrifugal cleaners is measured as a function of the pressure differential between the feed and accept streams, expressed in terms of the power consumed in the feed pumps that provide the pressure and velocity needed to make the centrifugal cleaner work.
