1.  wood pellets production line ----Raw materials Prepared
 Wood Pellets is mainly made of any wood waste and biomass particles,  such as wood sawdust, wood shavings, wood chips, wood logs, straw, rice  husk, coffee husk etc. At a wood pellet plant, raw material need to be  well prepared before pelletizing, then get dried, compressed, and formed  into small eraser-sized bits, the wood pellets get from wood pellet  plant are clean, pleasant smelling and smooth to touch.

 2. wood pellets production line ----Crushing process – Hammer mill

 The hammer mill is a machine whose purpose is to crush materials by the  collision between the high-speed hammer and materials. Our SFSP series  chipping and crushing machine is your best choice. It mill raw material  like tree branch, wood shavings, wood chips, wood logs, cotton stalk,  corn stalk, wheat straw etc, with size less than 50mm (diameter). After  milled, the output size can reach diameter 3-5 mm, then it is pushed to  next process to get dried and pelletized.

 3.  wood pellets production line ----Drying process – Rotary Dryer

 After crushing process, the wood and biomass material need to be well  conditioned on moisture before pelletizing. The best moisture content to  pelletizing is about 14-16%. 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 use steam to heat air and contact material to  remove certain degree of moisture. It is very important for wood pellet  plant to using moisture detector which will determine the most suitable  moisture before pelletizing.

4. wood pellets production line ---Pelletizing process - Wood pellet  mill

Ring Die wood pellet machine is the heart of the pellet machine  production line. The Pellet machine is widely used in compacting of  wood, straw, other biomass sources into pellet. Capacity ranges from 1T  to 10T per hour. Our series pellet mill adopt SKF bearings from  Sweden and NSK bearings from Japan, the motors in the wood pellet is  from Siemens, high quality components make the pellet mill more  efficient and durable.  

5. wood pellets production line ----Cooling process - Pellet cooling  machine

After the pelletizing process, the temperature of the wood pellet is  about 60-80 degrees Celsius, and the moisture content of the wood  pellets is about 15%. A cooler must then be used to reduce the moisture  content of the wood pellet to about 3-4%, thereby making the wood pellet  easy to store. However, some customers said that the local climate is  very humidity, they want to cool the wood pellets with moisture 7-8%. It  is no problem, our new stabilizer combined cooler can do it well.

6.  wood pellets production line ----Packing process - Pellet packing  machine

After cooling process, the wood pellets will not directly enter into the  fuel process, avoiding the wood pellet affected with damp, the packing  process is very necessary. The packing process is effectively handled by  our Semi-Auto Packing Machine.
