Straws are widely used in paper making, ethanol production or used
as feed for animals in the past, until recently, the new way of
processing these straws has caught people’s attention-that is
pelletizing. While with the development of pellet machine, straws
are available to use as raw materials of pellet making machine.
High quality straw pellet mill price/straw pellet machine supplier
is mainly developed for the materials of straw plants such as corn
stalks, wheat straw, cotton straw, etc. According to the different
materials, the suppressed particles can be used as a biomass fuel
as well as feed for livestock and poultry.
For people who want to use wood pellets instead of coal, gas, oil
and electricity, what they concern most is how to make pellets with
high quality straw pellet mill. In fact, the process is quite easy.
Steps to Make Pellets:
1. Prepare raw materials. For making pellets, raw materials can be
any kind of biomass, including sawdust, wood shavings, waste wood,
leaves, stalks, straw, etc. Since the pelleting process require raw
material to be smaller than 5mm, those raw materials larger than
this size need to be pulverized by hammer mill or wood crusher. In
addition, if the moisture content of raw material is too high (
15%), it need to be dried; if lower than 8%, it need to be added
some water and stir evenly.
2. Feed the raw material into the pellet machine. In this process,
the raw material must be fed steadily into the pellet machine
hopper, in case of blockages. When the roller or the die inside the
pelletizing chamber rotates and press the material, it will
generate high temperature (over 70 centigrade). The high
temperature will cause the lignin contained in biomass to soften
and be adhesive. Then together with the high pressure, the pellets
are pressed tightly to go through the die holes. Then biomass
pellets are formed. There is a pellet cutter to cut the pellets to
a certain length.
3. Cool the pellets. The biomass pellets just made out have high
temperature, in this case, they must be cooled to room temperature
to be used or packed.
4. And finally, you can enjoy the biomass pellets.
Having learnt about how to make pellets, you may have found it is
such an easy task. And surely it is. Although you will spend some
money purchasing the pellet making machine, but considering it will
be used for several years to make fuel pellets from costless
biomass, you will find it worthwhile!
