The feed pellet making machine is the vital machinery of the whole ruminant feed pellet plant. According to the unique digestive physiological characteristics and feed nutrition requirements of ruminants, cattle and sheep feed is very different from pig and poultry feed in terms of feed formula and feed preparation technology. The ruminant feed includes the feed of ruminant animals such as cattle, sheep, horses, and camel. The ruminant feed is divided into concentrate and a total mixed diet. The raw materials of ruminant feed mainly include corn, wheat, barley, soybean meal, and other grain raw materials (similar to livestock feed), as well as coarse fiber raw materials such as grass, hay, and straw. Ruminant feed pellets are characterized by coarse crushing fineness (4-8mm mesh diameter), low requirements for ripening and conditioning (single-layer conditioner is used for pelletizing), and large diameter of finished pellets (about 2-12mm in diameter). A grass pellet mill is mainly applicable to the processing of coarse (fiber) feeds such as hay, beet residue, and various straws. It is also equipped with arch breaking feeding silo. As forage and other materials are prone to arching, there is a broken arch feeding bin, which is convenient for subsequent granulation.
