The compression ratio of the ring mold is the ratio of the effective working length of the ring mold to the diameter of the mold hole. The compression ratio of the ring mold can be selected according to the raw material formula and product requirements. A low compression ratio can increase production, reduce energy consumption, and alleviate wear on the ring mold and pressure roller. But the particles are loose, with varying lengths, and the feed pulverization rate is high; On the contrary, the particles are solid, have a smooth and glossy appearance, have a low pulverization rate, but have high production costs. Users can choose the compression ratio of the ring mold according to their own needs, and the compression ratio of the ring mold for livestock and poultry pellet materials is generally10Below, the compression ratio of the ring mold for aquatic pellet feed is mostly10above.
The difference between ring mold pellet machine and flat mold pellet machine
1. Feeding method:
The ring mold pellet machine adopts mechanical forced feeding, high-speed rotating centrifugal distribution into the granulation chamber, and material distribution through a scraper, resulting in uneven feeding; The flat die granulator relies on the weight of the material itself to enter the pressing chamber vertically, which can evenly feed.2. Pressure:
In molds of the same diameter, the diameter of the ring mold wheel is limited by the diameter of the ring mold, so the pressure is limited; The diameter of the flat mold wheel is not limited by the diameter of the mold, which can increase the space for the internal bearings. Choosing large bearings to enhance the bearing capacity of the pressure wheel not only improves the pressing force of the pressure wheel, but also extends its service life.3. Discharge method:
The ring mold belongs to high-speed, and the damage rate is high when the material is discharged; The flat mold belongs to low speed and has a low damage rate.4. Adjustment method of pressure wheel:
If the ring mold granulator uses two screws on the eccentric wheel in the middle of the pressure wheel to adjust the pressure; The flat die granulator adopts a threaded thread column m100 central adjustment mechanism, with a top force of one hundred tons, smooth descent, soft impact, and uniform pressure. There are two ways to adjust: manual rotation and hydraulic automatic adjustment.Harbin Yongxing Machinery Equipment
