Bow screen is used for fiber recovery from white water in the process of paper & pulp making. Without rotation and vibration parts, the bow screen works without motor and it’s simple and reliable in operation.
Adopting upflow feeding structure design with pressure injection, liquid material is sprayed onto the curved plate in a tangential direction through a feed box with adjustable lip plate, the jet power pushes material forward through the surface of the curved plate. Depending on the jet power and gravity, the liquid and the fine particles pass through the gap of the screen plate, then aggregated to the filtrate outlet. The solids which can not be screened through the screen slots will be blocked by screen plate and flow to the discharge outlet along the direction of the material flow so the solid-liquid separation can be achieved.
