Reject Sorter - Pulp & Paper Machine

Parason Reject sorter is non-vibrating, low attrition, totally enclosed reject screen that remove debris in almost dry condition with minimum fibre loss. Parason Reject sorter is designed for handling reject of screening at Pulp mill/Stock preparation stage and to work with waste paper and virgin Pulp line. It is one typical last stage screen to handle last stage coarse screen. The reject sorter with special rotor is fitted with sweeping distributing blades of special hardened MOC. The rotor impels the stock fed a in against the screen half, cleans the screen half, cleans the screen half and disaggergates the fiber bundle for better for sorting.



Working Principles -



The pulp slurry, with concentrated rejects, enters the Reject screen. Showers in the screen wash fiber from the debris in the screening zone. The rotor clears and transports the debris along the length of the screen plate towards the reject end. Recovered fiber is accepted from the screen and can be fed forward / backward in the system. The interaction of the multi-pitch rotor, screen plate and internal baffling produce virtually fiber and water free reject that are suitable for transportation and disposal.
