It is a professional industrial use of grass pellet machinery that produces grass pellets. The key to grass pelletizing is the water content of the raw grass. First of all, we must measure the moisture content of the raw materials. Then, regulate it to an appropriate value by adding water or sun-drying. Research shows that the best moisture content for leguminous forage grass pellets is 14% to 16%. For Gramineae forage grass pellets it is 13% to 15%. In fact, grass pellets can also be used as fuel for heating if the moisture is accurately controlled. Grass pellets may produce more ash than wood pellets, and the calorie in grass pellets is not so much as in wood pellets, but grass pellets have still a well-accepted method in Europe for a long time. In a word, the grass pellets are an excellent choice for both feed and fuel.
