[0014] The beneficial effects of the utility model are as follows:
[0015] 1. The material enters the feed groove inside the ring cutting die head through the feed hole. As the material continuously enters the feed groove, it is continuously pushed upwards. When the material moves upwards, it is squeezed by the first and second diversion rings. The material is squeezed out from the gap between the first and second diversion rings and enters the uniform material chamber. Only when the uniform material chamber is evenly filled will the material be squeezed out from the pellet outlet due to the thrust. This ensures that there are no cavities before the material is extruded and pelletized, thus guaranteeing the uniformity of the pellets. This solves the problem of common water ring pelletizing dies, which only have a ring cutting function and can ring cut materials into pellets, but lack the function of uniform extrusion, and cannot guarantee the uniformity of the pellets. This can easily lead to uneven material distribution during extrusion, affecting the uniformity of pelleting. Attached Figure Description
