How Are Biomass Wood Pellets Manufactured?

Biomass wood pellets are made from the waste of some products, such as forestry residues, agriculture wastes, wooden wastes, and more. These pellets use in various forms and grades like electric power plants, homes, and other helpful applications. However, preparing these pallets with low moisture that is tremendously dense and burn and high combustion efficiency.

Moreover, biomass wood pellets equipment is available in different sizes and scales that allow industrial and domestic production.  

Preparation of biomass wood pellets

The preparation of wood pellets involves various steps. Here we will have a look at several steps : 

A truck arrives at the plant and sends wood to one of four places. The storage yard, the wood circle, the piles of sawdust and woodchips, or straight into the machine.

 

The bark is saving for fuel

For the further process, logs are put into a debarked machine to smash the logs together in a drum to remove the bark. Then the bark is put apart and made in use to fuel the woodchip dryer and then again use later in the process.

 

Thin wood stems turn into little bits

The logs, which are low-value fibre from sustainably managed working forests, must first be reduced in size before being shredded into the fine material required to make pellets. The logs are divided into around 10mm length by 3mm thick chips within the wood chipper with several spinning blades. The resultant chips are catering into the woodchip pile, so they can be screened.

Waste removal and chips are screened for quality check

Sand, leftover bark, or stones can be found in chipped-down wood and can interfere with the manufacture of pellets. Only ideal-size wood chips are left after the chips and process through a screener that removes the waste.

 

Your first-ever sighting of a huge hairdryer

Here is the need for the enormous hairdryer to have moisture for wood chips between 11.5% and 12%. If you do anything else, the quality of the pellets you get can suffer. The chips enter a sizable drum that receives a hot air blast produced due to heater-driven bark gathering from the debarked. The sizable fan moves the chips through the drum for the hammer mill.

 

Small woodchips continue to get smaller

There are several mounted hammers on a spinning shaft inside the hammer mill. The wood chips are fed into the top of the drum, where they are chipped and ground into a thin powder used for the creation of the pellets.

 

Putting the chips under a lot of pressure

The pellet mill receives the finely ground woodchip shreds. A spinning arm inside forces the wood fibre powder through a grating with numerous tiny pores. As the wood fibre goes through the holes in a metal ring dye and squeezes into wood pellets, the high pressure warms the fibre and aids in its binding.

 

Resting and cooling down

Fresh pellets from the mill need to rest and cool before being transported off-site since they are moist and hot. They are sent to silos that are huge and kept at low temperatures so the pellets can cool and harden in preparation for shipping.
