Screening
Screening is one of the key steps in the stock preparation process to remove contaminants, but also a required action to improve the sheet cleanliness and formation for the approach flow applications.
With a wide range of equipment, Kadant is in a position to design the most appropriate screen for both stock preparation and approach flow applications.
With the ID2 and ID3 new patented concepts for screening, Kadant is also bringing a revolutionary new approach to the market. This approach includes a soaring retrofit activity, adapting old existing screens to the most demanding technical conditions.
Screening can have several positions in the process and operate at various consistencies, including:
- Stickies and specs removal
- Plastics and large impurity removal
- De-flaking and de-flocculation
- Fractionation between long and short fibers
- Protection of downstream equipment
- Avoiding pulsation's
- High efficiency with low fibre loss
The position of the screen in the process and into the screening plant itself (primary, secondary or tailing) will help to define the most appropriate design.
