Feeding method: The ring die granulator adopts mechanical forced feeding, high-speed rotation and centrifugal distribution into the granulation chamber, and the material is distributed by the scraper, and the feeding is uneven; the flat die granulator enters the pressing chamber vertically by the weight of the material itself. , can feed evenly
Pressure: In a mold with the same diameter, the diameter of the ring die pressing wheel is limited by the diameter of the ring die, and the pressure cannot be adjusted. When pressing coarse fiber materials such as sawdust and peanut skin, it is difficult to form under the pressure designed by the machine, even if it is formed. Due to the overloaded work, the machine wears a lot, the die pressing roller skin needs to be replaced in time, and the die can only be used once, and the follow-up cost is very large; The large shaft is equipped with a special heat-treated mold below. The rotation of the mold drives the rotation of the three pressure rollers above. The pressure is adjustable, the output is stable, the particle density is high, and the mold can be used on both sides. In addition, the diameter of the flat die pressing wheel is not limited by the diameter of the die, which can increase the space for the inner shaft. The large bearing is selected to enhance the bearing capacity of the pressing wheel, which improves the pressing force of the pressing wheel and prolongs the service life.
Discharging method: the ring die belongs to high speed, and the breakage rate is high when the material is discharged; while the flat die belongs to low speed, and the breakage rate is low
Pressure wheel adjustment method: The ring die granulator uses two screws on the eccentric wheel in the middle of the pressure wheel to adjust the pressure; the flat die granulator adopts the center adjustment mechanism of the threaded screw column, the top force is 100 tons, the falling is stable, the touch Soft strike and even pressure
The raw materials of concentrated feed are generally corn and soybean meal, etc., which are easy to be formed with high viscosity and can be formed without a lot of pressure. For the high-temperature granulation of hard-to-form crude fibers such as sawdust, straw, grass powder, and waste tires, and the granulation of organic fertilizers such as municipal solid waste, sewage treatment, and animal manure, flat die granulators are still used.
