Pellet mill is the efficient pelletizing device which is widely employed in pellet production line. It can be divided into two types by die mould design: flat die pellet mill and ring die pellet mill. In small and medium sized production, the former is superior to the latter based on its unique merits of easy operation, low consumption, competitive price. Compared with ring die pellet machine in different aspects, flat die pellet mill own the following outstanding superiority.

1. Even feeding way

flat die pellet mill working principle

Ring die pellet mill adopts forced feeding method. Raw materials enter the pelletizing chamber through high speed revolution, then the scraper in the machine distributes the raw materials. This feeding way can not feed uniformly, which is inferior to that of flat die pellet machine. Flat die pellet mill can feed evenly for the raw materials directly enter into the crushing chamber rely on their own gravity.

2. Changeable pressure

With the same diameter mold, the roller of ring die is limited by the mould diameter, so the pressure is restricted. However, the flat die pellet mill does not have this problem. You can enlarge inner bearing space and choose a big bearing to increase the bearing capability, which not only improves the press power of the roller, but also prolongs the service life. With changeable pressure, flat die pellet mill can process variety of materials especially crude fiber materials like sawdust, stalk, straw, peanut shell and so on. But for ring die pellet mill, it may result in roller bearing wear or broken to compress crude fiber materials due to its unadjustable pressure.

3. Low breakage discharging way

Ring die belongs to high rotary speed, the materials percentage of damage is high. Compared with ring die, flat die is of low-speed revolution, so the breakage is lower. Besides, flat die wood pellet mill can pelletize the pellet with more smooth surface.

4. Greater mobility

Ring die pellet mill is in large structure so it is not easy to move it. Flat die pellet machine is with little space and you can move it anywhere you want, which is convenient for pelletizing. Moreover, the portable flat die pellet mill is less wear and tear compared with ring die pellet mill.

Flat die pellet mill is characterized by low energy consumption, good efficiency and competitive price and gets more and more popular in the market. It is worthy investment for small scale family workshop. We are expert in design and manufacturing pelletizing solution and supply variety of models of flat die pellet mills driven by diesel or electricity engine.
