Centripetal Pressure Screen Knotter – IPS

Centripetal pressure screen – knotters PS homogenise flowing stock before paper machine headboxes and at the same time they protect them from accidental impurities. The design of centripetal knotters is an optimal solution for primary fibre stock of low consistency in the terms of throughput, energy demand and output pulses. The knotter inner design is optimised in the terms of a constant throughput including polishing all the surfaces after the screen preventing formation of deposits. The IPS outflow chamber is uniquely designed to enable high throughput, to prevent output pulsations and to enable the removal of bearing body without dismantling the belt pulley.

Design

The IPS design has a compact closed design with a vertically placed cylindrical screen wiped from outside by a turning lowpulsation rotor. Small sized knotter drives are placed on frames while the larger ones are placed on concrete foundations. A great advantage is an easy service due to the possibility of removing the bearing body without dismantling the belt pulley.

The machine design and safety are in compliance with the EU standards and EAC.
