3. Thickness
Thickness wood pellet machine die is another factor needs to be considerate. The thickness of the die can be divided into total thickness and effective thickness. The total thickness of the die refers to the overall thickness of the die which is larger than the effective thickness which refers to the working thickness of the pellet die, which the pellets are molded. The die is stronger when the die is thicker. Commonly, pellet die thickness increments vary by 1/4” between 11/4” and 5” thick.
The thickness has a decisive influence on how the material flows through the die. If it is too deep, the biomass materials cannot get sufficient compression to form pellet. And on the contrary, if it is too shallow, the biomass materials will get the pellet machine die blocked easily and shorten the service life of wood pellet machines.
In the study of C.R. Stark on influence of die thickness to feed pellet quality and production rate, he pointed out that thickness of pellet dies has a positive effect on pellet quality and negative effect on the production rate.
