Fibermizer is a screening machine used for the reject handling. It is used for reject handling in coarse screening as well as fine screening where the amount of rejects is more in quantity and contains fiber flakes.
The paper stock enters tangentially 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 enter the screening zone. Due to the reduction in size, fibers pass through the screen basket and leave the machine as accepted stock.
The rejects from the screen basket are discharged continuously from the reject nozzle. Due to differential pressure, a portion of the rejects are recirculated back in the feed chamber again to reclaim maximum fiber.
Max. fiber recovery & low power consumption
Effective reject handling
Useful where size of flakes is bigger with plastics
