Screening problems
1. Feed screen system from pressure loop to maintain a constant inlet pressure regardless of changes in downstream capacity. 2. Eliminating foam in primary screening operations prevents the loss of good fiber from the system and improves efficiencies. Accept quality is too low: 1. May need to improve feed quality. — poorly defibered stock will […]
Screen efficiency
1. Keep the screens clean. 2. Ensure that slots or holes are not narrowing due to pitch deposition. 3. Perform regular mechanical inspection of the foils and maintain proper clearances. 4. Perform regular inspection of the baskets. — check size of holes or slots. 5. Perform regular mechanical inspection of gearbox, glands and drive. 6. […]
