Binding Qualities, Material Density-Wood Pellet Mill Equipment

To make quality pellets by wood pellet mill equipments, you should pay more attention to binding qualities and material density.

Binding Qualities: Binder is the glue that holds a pellet together which helps the wood pellet mill producing pellets with smooth shine; some materials have enough lignin, which is a naturally occurring binder from within the raw material. If the material lacks lignin to bind the material together supplement binders can be added to create a pellet. One of the simplest binders is vegetable oil; this can also be added via peristaltic pump into the material. Generally oily products such as rape cake and dried distillers grain act as suitable binders.

Material Density: A pellet is formed through heat and pressure provides by wood pellet mill equipments; therefore a materials density dictates the heat and pressure within the pellet equipment. Material density can influence pellet quality and wood Pellet mill productivity. Materials, which have a high density, for example hard woods require more heat and pressure to form a pellet, therefore pellet quality can be an issue and low wood pellet equipment productivity. On the other hand low-density oily materials such as rape cake and dried distillers grain produce smooth hard pellets with high pellet mill productivity. Some materials with a low density but without oily properties struggle to compress into a pellet, as not enough pressure and heat is generated in the wood pellet mill equipment.
