The pellets production plant is composed of machines connected together as to create the production cycle. This cycle is different in every plant because the features of the product (species of wood, size, moisture content, initial condition, ...etc.) are always different.
The plant can be divided in sections, and according to the customer's requirements we are able to automate and supply the whole plant or automate individual sections of the plant.
1.Feeding: crushing, sorting and selection
The particle size of the material used is one of the fundamental parameters when choosing the feeding systems of the line. Two type of machines to feed the material can be chosen:
-Crushing or chipping machine with belts or chains
-Selector and/or sorting machines with hydraulic extraction hopper or worm screw.
Moisture content is a very important parameter for the production of pellets. If moisture content of the material to be processed is higher than 12% UR, the line requires a dryer, which needs a generator to produce hot air, or more in general, heat than can carry out the drying process.
3. Preparing the product
The dried product subsequently undergoes de-dusting, selecting and refining, where it is taken to the maximum particle size of 6-7 mm required for the production of an even/homogeneous product. From here it will be conveyed to storage and to the subsequent final transformation.
4. Producing the pellets
The material prepared is transformed into pellets by a pellet-making press. The pellets production line ends with the cooling (air/product) and de-dusting of the pellets. The line also includes an auxiliary, general dust suctioning system with filters which treat the air to be discharged into the atmosphere.
5. Bagging the pellets
Once they have been cooled and cleaned, the pellets pass through a weighing system before being packaged into specific customised sack or big bags. The palletizing system is the final part of the line.
