When you choose a feed granulator or fertilizer granulator, you will consider which type of granulator to choose. Today, Huaqiang Heavy Industry will briefly introduce the difference between
flat die granulator and ring die granulator.
①Feeding method. Flat die pelletizer relies on the weight of the material to enter the pressing chamber vertically, and can feed evenly; ring die granulator adopts forced feeding, high-speed rotation centrifugal distribution into the pelletizing chamber, and the material is distributed by the scraper, and the feeding is uneven;
②Pressure. In the mold of the same diameter, the size of the flat die pressing wheel diameter is not limited by the diameter of the mold, and the internal bearing space can be increased. The large bearing is selected to enhance the bearing capacity of the pressing wheel, which not only improves the pressing force of the pressing wheel, but also extends the service life; the size of the ring die pressing wheel diameter is limited by the diameter of the ring die mold, so the pressure size is limited;
③Discharging method.
Flat die granulator has a low speed and a low breakage rate; ring die granulator has a high speed, and the breakage rate is high when the material is discharged;
④Pressing wheel adjustment method. The flat die pelletizer adopts the threaded column m100 center adjustment mechanism, with a top force of 100 tons, stable fall, soft impact, and uniform pressure. It can be adjusted manually or automatically by hydraulic pressure. The ring die granulator needs to use the two screws on the eccentric wheel in the middle of the pressure wheel to adjust the pressure. It can be concluded that for coarse fibers such as sawdust and straw, which are light and difficult to form, it is better to use
flat die granulator.
