Large Pellet Mill

Brings You Healthy Living and Green Future
As a green and recyclable fuel, pellets have received welcome from increasingly people for different purpose. You can take wastes into pellets easily for your daily life or for business. But if you mean to pelletize in a large scale, you may face troubles with your pelletizing machine during pelletizing like followings:
“Don’t worry” Ring Die Pellet Mill can solve above problems.
Ring die pellet machines are one type of the hot pellet mills in the world. Compared with the flat die pellet mill, those ring die ones should be not so widespread for its increasing complexity and higher costs. But the ring die pellet mills are the definite choice to conduct a large-scale wood pellets producing for industrial or commercial purposes. Just as its name describes, this machine has a wide cylindrical die and is mounted vertically, rather than flat and horizontally as with a flat die. When you are going to put the biomass materials inside the pelletizing machine door, you can feed them with a surge bin to make them through a variable speed conditioner. A screw auger is significant for the last step to sending materials into the pelletizing machine chamber.

Anti-Cracking Technology   Cold Molding Technology   Structural Improvements
 1. Not suited to customers' own raw materials.
 2. Ring die is easy to crack.
 3. The output is too small.
 4. Press roller and bearings damage frequently.
 5. High temperature, excessive dust and unstable run.
 6. Equipment consumption is too high and the
 processing is not too complicated but difficult to operate.
Key Technical Points:
PM420 and PM508 have a same appearance and performance, but they are different in inner diameter of the ring die and productivity. Besides, the power of KMPM420 is 90kw, while that of KMPM508 is 110kw.
Our machine adopts high-precision gears for maintransmission. And the ring die is easy to discharge and of shroud ring. With these, the efficiency of our machine increases by 20% than that of belt-drive pellet mill with bi-motor.
The transmission part employs imported bearings and oil seal, which make the transmission steady, high efficient and of low noise.
The advanced compensation type serpentine spring coupling of international level is featured by novel and compact structure, high security and low breakdown rate, etc.
Main components have been strengthened by adopting special materials like heat treatment and other technologies so as to meet the need of biomass pelletizing.
Adding of non-stop refueling system and cooling system makes the quality of pellets higher, running stable and consumption low.
Our ring die is national patented, which produce pellets stable and is not easy to craze.

Note: There have more material can be processed, for example: Wood, straw, grass, paper, hops, manure etc.
Every material you have we can have a try!
Biomass pellet resources means processing renewable materials collected from forestry or agriculture waste to columned form so as to facilitate transportation and improve the burning efficiency. The recyclable energy can include sawdust, corn straw, reed rod, rice husk, straw, straw, bamboo crumbs, shaving, rubbish, plastic, sugarcane, bark, log, garden pruning, silt, cloth and some other organic matters. All of them can be processed into pellets. But it is worth noting that pellets made from different materials contain different calorific value, produce different contents of ash, and are suitable for different market needs.
