Fibermizer is the screening machine for the reject handling.it is used for reject handling in coarse screening where the amount of rejects are more in quantity and contains fiber flakes.
The paper stock enters tangentially into the machine into the feed chamber.The action between the rotor blades and defibrating ring bars creates mechanical shear which breaks down larger fiber flakes and bundles before they enters screening zone, due to reduction in size, fibers passes through the screen basket and leaves the machine as accept stock.the rejects from the screen basket are discharged continuously from the reject nozzle.
Due to differential pressure, portion of the rejects are recirculated back in the feed chamber again to reclaim maximum fiber
The Advantages Are
Maximum fiber recovery
Lower power consumption
Effective reject handling
Useful where size of flakes is bigger with plastics
