Flat Die Pellet Maker Vs Ring Die Pellet Maker Machine
- What is Flat Die Wood Pellet Maker?
Flat die pellet presses have many options on engine selection, such as electric engine, diesel engine, gasoline and PTO (power-take-off, pellet mill without engine which should powered by agricultural equipment).
Due to the simple structure, low cost and simple maintenance, it is more suitable for home-use, small-scale wood pellet production and individual users, and widely used for DIY making your own wood pellets at home or on farm. However, this kind of small wood pellet maker is not good if used in industrial or commercial pellet plant, mainly because the pressure is small, the output is also relatively low.
- What is Ring Die Wood Pellet Maker?

- Difference in Pelletizing/Extruding Pressure
The flat die pellet maker machine adopts three conical press wheels with complete steel structure and a big shaft in the middle, and the die with special heat treatment is installed underneath, the rotation of the die drives the three press wheels above to rotate, the pressure is adjustable, the output is stable, the density of sawdust/wood pellets is large, and the die can be used on both sides. In addition, the size of the diameter of the flat die press wheel is not limited by the diameter of the die, so it can increase the space of the internal shaft and choose large bearings to enhance the bearing capacity of the press wheel, which improves the pressing force of the press wheel and prolongs the service life.
