Grass pellet machine is the main equipment for straw pellets producing. We need consider moisture content in the straw,fibre strength, particle size and natural binders. All these influence the pellet quality.
Application of straw pellet
1.Straw pellet for animal feed Straw pellets is a good pellet fodder for animals. It’s pressed at high temperature,which through tempering and gelatinization treatment. The pellets are dried in and out, so that the pellets have a “grass flavor”,which is an ideal food for all ruminant, cattle sheep,horse and rabbit .
