Feed pellet machine is according to the breeding of livestock breeding requirements, the mechanical, chemical, heating and so on the many kinds of methods feeding raw material into feed grain machinery. The add feed grain mechanic modulated finished product feed have powder, granule, broken section shape, flake, block, paste slurry of single feed, mixed dilute feed, and powder, granular feed, etc.
          According to the processing object and processing technology is different, feed grain machining machinery can be divided into the following categories:
          1, concentrated feed processing machinery for processing all kinds of grain, basically have feed mill, pellet mill and feed flattening machine, etc.
          2.Feed processing equipment, including feed flattening machine is to use a pair of relative rotation of the tooth surface roll or smooth roll, the cooking of grain crush in sheet mechanical bread slag, bread meal feed processing machinery oil crops the hydraulic oil press oil the diameter of about 250 ~ 600 mm bread slag, usable cake class mill grinding used as feed. The screw oil press oil the bread slag, and the leaching method lard oil from the proceeds after bread meal, can use hammer type feed mill grinding used as feed.
          3.Roughage processing machine is mainly used for processing hay, green and crop straw, etc. The commonly used have stalks cutter, stalks tempering machine, feed mill, grass block press and pellet mill, etc.

          Stalks tempering machine is to use alkalize method processing crop straw, namely the caustic soda or other alkaline solution through the line holes uniform spray to cut up after the straw, in the course of transmission to fully mix, the straw lignin decomposition, in order to improve the rate of digestion, clear mould, and disinfection effect.

          Straw briquette machine is to cut up after the hay and roughage compressed into pieces, its density could reach 600-1000 kg/m3, easy to transport and storage, feeding can be directly into the feeder. Its working principle and feed grain machine similar, but grass block size large.
