Pellet Mill for Biomass Materials

Ring die Pellet mill for biomass materials

The ring die wood pellet mill to process biomass materials is belt drive design which is same as following photos.Ring die pellet mills are preferred to flat die mills in large scale commercial and industrial production. Ring die pellet mills are not as widespread as those with flat dies due to the machines' greater complexity and higher costs. As the die's name suggests, the ring die has a wide cylindrical shape and is mounted vertically, rather than flat and horizontally as with a flat die. A surge bin is used to feed biomass materials through a variable speed conditioner before being distributed through the pellet mill door. A screw auger is useful at this last step in centering the materials in the pellet mill chamber.

Advantages of Ring Die Pellet Mill:There are two main advantages in using ring die pellet mills. First, ring die pellet mills generate less wear and tear since both the inner and outer edges of the roller traverse the same distance. Second, ring die pellet machines are more energy efficient than the flat die pellet mill. Roller slip during the pelleting process brings extra friction, but this extra friction is a good element in the production of quality wood pellets due to the additional heat.

 The parameter and data of Ring Die Pellet MIll:

MainFeatures:

1. 98% energy transfer - meaning less energy wasted
2. Adopting aerodynamics technology & The current round principle, reduce the temperature in pelletizing chamber and keep around90°C, as a result the machine can work well continuously

3. Timing feeder can control the feeding speed to lower the block ratio

4. The body is more durable because we use ductile iron

5. Capacity increased after adding another force feeder made from stainless steel to increase the feeding spread area

6.The key working part become stronger after modifying the material, heating processing technology etc..

These main parts are forging pieces. Now, the processing of our ring die can reach to800-1000MT. Ring die is assembled by quick-discharge clip

Other features:

1. High efficiency, lower power consumption, stable operation and production

2. Using imported bearing (NSK) & seals to get better transmission performance, stable operating, and less noise

3. Stainless steel ring die resists corrosion and lasts longer.
4. Multi-positioning feeder enables easier installation and alignment to bins

5. Stand-alone oil lubrication system is more effective in maintaining lubrication and keeping the bearings from premature wear
