Cleaning
Cleaning involves converting pressure into high speed through the introduction of stock into small cones. The stock, introduced tangentially, is forced to rotate at high-speed resulting in high centrifugal forces. Most particles with a density over one 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.
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 step in any secondary fiber line.
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
Features and 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 deinking lines
- Virtually sand-free accepts
- Wide range including HD cleaners for the heavier particles and the Gyroclean for the removal of light weight contaminants
