characteristics :
1. Vertical feeding directly in place. 
2. Die static, roller rotating, materials centrifugal, Evenly distributed around. 
3. Double-layer dies, up and down dual-use, reduce the cost, enhance the efficiency, can be dual-use, high capacity, energy saving. 
4. One die, different hole diameters, with different specifications to pelletize. 
5. Macroporous die, wire joining circular tube, increasing travel, improving density. 
6. Ring die, vertical structure, good for cooling the pelletizing room.
