1、 Feeding mode: the ring mold granulator uses mechanical forced feeding, high-speed rotating centrifugal distribution into the granulation chamber, through the scraper to distribute the material, the feeding is not uniform; the flat mold granulator relies on the weight of the material itself to enter the pressing chamber vertically, which can feed evenly.
2 Pressure: in the mold with the same diameter, the diameter of the ring mold pressing wheel is limited by the diameter of the ring mold, and the pressure can not be adjusted. When pressing coarse fiber materials such as sawdust and peanut skin, it is difficult to form under the designed pressure of the machine. Even if the molding is overloaded and the machine is worn seriously, the mold pressing wheel skin needs to be replaced in time, and the mold can only be used once, and the follow-up cost is very high The flat die granulator adopts three conical pressing wheels with complete steel structure, a big shaft in the middle, and a mold with special heat treatment is installed below. The mold rotation drives the three pressing wheels above to rotate, with adjustable pressure, stable output, high particle density, and both sides of the mold can be used. In addition, the bearing diameter of the flat wheel can be increased, and the service life of the flat wheel can be extended.
3、 Discharge mode: the ring mold is of high speed, and the damage rate is high when the material is discharged; while the flat mold is of low speed, and the damage rate is low
4、 Pressure wheel adjustment mode: the ring mold granulator uses two screws on the eccentric wheel in the middle of the pressure wheel to adjust the pressure; the flat mold granulator uses the center adjustment mechanism of the screw thread column, with a jacking force of 100 tons, stable falling, soft impact and even pressure.
