The process of cutting is necessary because the dimension of the raw material has to be reduced. The raw material could be in two parts: round or rectangular bales. The cut product can be transported with normal transportation systems. It could be dry or humid, in the first case it can go to the refining phase, in the second case the product has to be dried in order to have a suitable humidity to pellet.


The humidity percentage of the wood must be reduced from approx 80-90% to not more than 12-13%. The machine could be a rotary drum drier or a belt drier and has a burner that can be alimented with oil, gasoline, gas or wood.


After drying a refiner mill, complete with aspiration unit, reduces the dimensions of the product and prepares it for pelleting.
The product is also cleared from any ferrous part.


A mixing silo make the product homogeneous and in this silo the product can be stocked.


The material is entering in the pellet mill passing through the conditioner. Here other ingredients could be added, before the material goes into the pellet pressure chamber to be transformed into pellets by the die. On the outside of the holes some knives cut the pellets at the desired length.


After pelleting, the product is very hot, therefore it’s necessary to cool the product at approximately +5°C in respect to the room temperature, in order give it the right hardness and the best consistence to store and handle it.
The machine is a counter current cooler complete with air aspiration line the recovery of dust.


In this phase the product is cleaned from the dust, which is brought back into the production cycle.


The pelleted product is conveyed to the silo for storage before delivery.
It can be delivered in bulk, loaded on trucks or packed in sacks or big-bag. The machines for packaging could be manual, semi-automatic or automatic, based on the requested production.
