PLC general control system fully automatic pellet processing pellet
making pellet line
This pellet making line can make the wood pellets by sawdust,it
also can collet the material,mix and adjust the quality to make
small and roundish pellets.The technological process is rational in
succession Every unit's performance is good. the aricrew
cooperation is compact.The whole pellet making line take small area
and has small energy consumption. It also can make pellets from all
kinds of grain straws.
The standard pellet making line mainly contains wood crush process,drying process, pellet making process,cooling
process,packing process and waste air handing process,The final
pellet has good quality and meet the europe standard.
Advantages of wood pellet fuel:
1. Environmental Friendly.
2. Easy to store and transport.
3. Wide application and good market.
4. Effective. Wood pellets generate high heat output.
5. The raw materials are available locally, sustainable and
6. Wood pellets cost is affordable and predictable. It is more
stable than the ever-increasing price of fossil fuels.
Detailed Description of pellet making line:
|1||apply for||Wood Pellets are mainly made from any wood waste and biomass
particles,such as wood sawdust,wood shavings,wood chips,wood
logs,straw,rice husk,coffee husk etc..|
|2||final product||6mm,8m,10mm,12mm,the length can be adjusted according to the
requirement of the client.|
Mainly Involved processes:
Wood crushing (if the raw material is not already
granulated),material sieving, drying (if the raw material contains
too much moisture),pelletizing,cooling, screening and packing.The
whole pellet making line can be highly automatically controlled..
1 to 10 ton per hour is available.
Process of complete pellet making line
Crushing process – Hammer mill
The best material diameter for supporting to produce pellet is
1-5mm.Thus if your material diameter exceed 5mm,then you need
crushing machine to crush and grind them into small powder 1-5mm
for supporting to produce pellets.
Drying process – Rotary Dryer
The best moisture content to pelletizing is about 12-18%.our rotary
dryer is made up of burning stove and main rotary dryer which is
high efficiency in drying the wood and biomass material.It can
realize to reduce the moisture from 50% to 10%. The rotary dryer
uses steam to heat air and contact material to remove certain
degree of moisture.It is very important in pellet making line to
use moisture detector which will determine the most suitable
moisture before pelletizing.
Pelletizing pocess - Wood pellet mill
Pellet mill is the heart of the wood pellet making line,it should
have reliable running performance.Our MZLH series Ring die pellet
mill is designed for large scale production.
Cooling process - Pellet cooling machine
Usually after pelletizing,the temperature of wood pellets is
between 60-80 degrees and the moisture content is close to 15%.For
storage purposes, a cooler must be used to reduce their surface
temperature and the moisture content,also help screen good and pure
However, considering the feedback from some foreign clients,the
local climate is very humidity,they hope to cool the wood pellets
with moisture 7-8%.In order to satisfy different needs from
different clients,we develop one kind of new Stabilizer Combined
Packing process - Pellet packing machine
The packing process is effectively handled by our Semi-Auto Packing
Biomass pellet making line benefits
1. When burning,less ashes reminded,air pollutants emission reduced
and carbon neutral without exacerbating the global warming.
2. A wide range of raw materials adaptability includes wood
materials, agricultural by products,even wood wastes from wood
3. Regular and uniform shape,easy to ignite,high heat
output,convenient to store and transport, especially suitable for
automated heating system.
4. Wood pellets can be used for home heating and industrial boilers
and large power plants as well as animal bedding.
5. It is applicable for stoves,furnaces,boilers and other heating
