Wood Pellet Plant FAQs

There are a wide range of raw materials which can be made into fuel pellets by wood pellet mill. You can find the suitable raw material almost everywhere on the earth. Some of them are unwanted and useless wastes. Some are agro-residues. Some are factory scrap. For example, live garbage, production trash, crop straw, branches, bark, leaves, wood scraps, rice husk, peanut shell, sunflower seed shell, bamboo shavings, bagasse, palm shell.

It is a professional terminology referring to a key part of pellet making machine. It can be seen as the mold of pelletizing. The quality of pellet die largely affects the quality of final pellets. Pellet die is generally made from high hardness stainless steel alloy. To ensure high finish degree and long service life, pellet die will be processed through vacuum heat treatment and precision finishing. Pellet die can be divided into flat die and ring die. Wood pellet mill can also be divided into flat die pellet mill and ring die pellet mill depending on the pellet die type. Flat die pellet mill is suggested for small scale pellet production and individual use, such as home heating or cooking. Ring die pellet machine is suitable for large pellet production and industrial use.

Pellet roller works with pellet die, constituting a die-roller assembly. There are at least two rollers and one die mounted in the pellet mill chamber. For flat die pellet press, there are die-turned type and roller-turned type. For ring die pellet press, the rollers are subject to the die. During the pelletizing process, high pressure is produced between the die and roller. When the raw materials are fed into the machine chamber, the roller will press them towards the die. After the feedstock is forced through the die pore, pellets are made. You need to adjust the position of the roller and die to achieve good pelletizing effect.

Compression ratio is related with the diameter and length of pellet die pore. It is a key factor which affects the effects of pelletizing. Different raw materials have different requirements on die thickness and pore size. There are two ways of calculating the compression ratio. One is die pore diameter to die efficacious pore length; the other is the pore diameter to efficacious pore length and relief area. For more information, please feel free to contact us.

Raw Material Breed: Some biomass materials are easy to pelletize while others are hard to process. For hard-to-process materials, adding appropriate binding agent can help improve the pelleting result. Feel free to ontact us and ABC Machinery is very glad to share binding agent knowledge with you!
Raw Material Moisture Content: 12% to 15% is suggested. (It is a rough value range calculated according to project experience.)
Feed Stock Size: 3mm to 4mm is suggested.
Besides, feeding speed, compression ratio and pelletizing experience are all matters.

Yes, on-site installation is available. But the installation cost is not included in the quotation since it is a kind of individual demand. So you need to pay extra if you need on-site installation.
