As preferably, described cloth wind frame circumference is provided with the second wind distributing hole.
Hot blast in described first wind distributing hole and the second wind distributing hole can pass through air inlet air intake jointly, and described second wind distributing hole contributes to preventing particle deposition further on described wind-distributing pipe.
More preferably, the diameter of described second wind distributing hole is greater than the diameter of described first wind distributing hole.
As preferably, described twin fluid atomization spray gun is tilted to down, is 5 °-10 ° with the angle of horizontal plane.
The location arrangements of described twin fluid atomization spray gun can make the auxiliary fluidization of forging a knife better.
As preferably, the upper surface of described first wind distributing hole is provided with the calotte raised up.
The effect one of calotte to change air flow, makes particle even granulation in granulation tower; Two is to prevent less particle from directly leaking down from wind distributing hole.
More preferably, the first wind distributing hole in described calotte is 5-8.
More preferably, be positioned at below described sprayer unit and be provided with anti-collision net above described reclaiming plate.
The effect of described anti-collision net be prevent particle comparatively large or flow velocity is too fast time calotte is pounded.
As preferably, described twin fluid atomization spray gun has 2, is disposed in an evenly spaced relation in described granulating fluidized bed madial wall.
In sum, the present invention has following beneficial effect: bed is stable, granulation evenly, not leakiness material; Cloth wind is even.
