Cleaning
Most contaminants have a density which is higher than fibre, including many stickies, most black specs and sands. Other particles have a density similar to fibre, but a larger size which makes them easy to separate through centrifugal force. This is the reason why cleaning is a key required strategic step in any secondary fiber line.
Working Principle
Cleaning involves converting pressure into high speed through the introduction of stock into small cones. The stock, introduced tangentially, is obliged to rotate at high speed which results in high centrifugal forces. Most particles with a density over 1 are projected against the inner cone wall until they reach the lower section of the cleaner. Stock is attracted by the central
vortex and accepted at its upper section.
Applications
- Specs and sand removal in secondary fiber lines
- Stickies removal
- Approach flow for improved paper machine protection and runnability for both secondary and virgin fibre lines
Benefits
- The third generation cleaning concept resulting in improved efficiency and reduced power consumption
- Polyamide free designs which result in less wear
- Excellent large ink removal for the models designed for de inking lines
- Virtually sand free accepts
- A very large range to satisfy all needs including HD cleaners for the heavier particles & the renowned Gyroclean for the removal of light weight contaminants
