Binder is used for bonding wood materials together to form the granule form. The usage of binder can decrease energy consumption, reduce wear and tear, and improve productivity of home pellets mill. Various binders can be used, including sand, water, modified cassava starch, etc.
As materials and working principle of home pellets mills are different, their needs of binder can depend. Usually, there is lignin combined in wood materials. Under great force and high temperature, it can melt to be a natural binder of wood pellets.
Home pellets mills developed by our company can be categorized to two kinds: the flat die pellet mill and rotary roller pellet mill. When they are pelletizing, little binder will be needed. Lignin in the wood will play a significant role in bonding. The rotary roller pellet mill even doesn’t need any other binders. If you are interested in this, please contact us.
