Low speed dispersion (kneading)
Working Principle
Stock is introduced into a drum casing and is pushed by a screw into the kneading area. Stock is forced to pass through a limited clearance created by stationary fingers fixed in the casing, and mobile fingers fixed on a rotating shaft. A counter pressure is created by a pneumatically actuated flap which permits precision adjustment of the kneading effect.
Applications
- Specs dispersion
- Complementary ink detachment for 2 loop de inking lines
- Stickies dispersion
- Oxidative bleaching mixing
- Final defibering/deflaking for difficult wet strength Applications
Benefits
- Excellent dispersion effect
- Limited maintenance
- Very high runnability
- Not detrimental to fibres (no cutting effect)
- Optimal use of power
- Excellent for ink detachment (low speed and high friction, no attrition)
- The best known mixer for bleaching due to high friction
