Raw material particle size and
moisture content of woody biomass that meet for specific technical requirements
as long as adequate quantity then can be directly processed into wood pellets
with pelletiser. Stages such as debarking, size reduction, and drying become no
need to be done with the raw material in these conditions. The shorter route in
the process so it will be more economical production processes are carried out.
This is the ideal choice that be searched by all manufacturers of wood pellet.
Ideal conditions are not plentiful but can be met in some industries.
Waste wood shavings (planers) due to
the small its particle size and already
dried (MC~10%) generally can be directly processed into the pelletiser for the
production of wood pellets. Just an additional equipment, that is hopper as a
temporary reservoir is usually required before pelletiser for maintaining the
stability of the supply of raw materials to the pelletiser continuously. The
availability and sustainability of such raw materials would become one of the
key success factors for the production of wood pellets. The dried raw material
but if the raw material size is still quite large such as wood chips can not be
directly fed into the pelletiser for wood pellets.
