Centrifugal Cleaner Troubleshooting

Centrifugal cleaners are widely used in the pulp and paper industry to remove contaminants from pulp fiber suspensions based on density differences. They can remove everything from nails, staples, and pieces of glass, to sand and grit, to lightweight plastics and adhesives . Besides improving the appearance and strength of the final product, cleaners protect downstream equipment from damage and wear.

The setup and design of each cleaning system are based on the nature and concentration of the contaminants targeted for removal, characteristics of the pulp fiber suspension, and end product requirements. In some cases, a single large cleaner or set of cleaners can perform the job. In others, multiple banks of cleaners arranged in three or more stages are required.

Centrifugal cleaner operations affect downstream equipment reliability, machine runnability, and product quality, which is why it is so important to take action to get cleaner systems back into their desired state when an issue develops. This course covers the key operating variables for centrifugal cleaners, common issues, possible causes and corrections for those issues, and best practices for troubleshooting centrifugal cleaners.
