FQJ Series Light Impurity Separator

FQJ series light impurity separator(also known as apple screen, for its shape looks like apple) can efficiently remove light impurities in paper pulp and it also can used for dealing with tail pulp in the coarse screening section of pulp manufacturing line.


1. The main body is an inverse conical design, concave top structure can form a strong vortex, forming a low pressure area in the top center and getting the light impurities and discharge them outside effectively.
2. Pulp outflow chamber of rotor is higher than undersurface of shell, forming a low pressure area around the rotor to collect heavy impurities. Under centrifugal force, the heavy impurities are thrown to the outermost of eddy and deposit in the groove that is outside the sieve plate for discharging. At the same time, it will reduce the wear to cutter and sieve plate, prolong the service life of them.
