1,Robust in operating, no shut down even at full load, and separate feeding device not needed,
2,Versatile available, feed production may be arranged after manure without being idle for later half year,
3,Pellet produced in one process, without over size and recycling , pelletizing rate larger than 90%, drying and cooling ability available, resulting in low production cost and good for seeding machine,
4,Low moisture content in feed stock requested, easy to drying and post treatment, low cost for drying. Because drying could be conducted with low temperature or sun, so activity of biological bacterium would not be impacted,
5,Spare parts not easily worn, cost low,
6,The problem of sticking to disk for higher urea content in green manure successfully smoothed,
