Abstract:

There are plenty resources of crop straw in China. The paper had a comparative study on the performance, usage, raw material and technological process of the biomass pellet and pellet feed for transformation usage of energy and feed with remaining straw. The results showed that: because of the differences between the material component and process route and working conditions of the biomass pellet and pellet feed, the abrasion of molding equipment was distinct. The process route of biomass pellet was shorter, and conditions were more complicated, so the key parts were unable to achieve the designed life, and led to maintenance costs increasing. In order to reduce the design life of biomass pellet molding equipment, the construction and components can be optimized consulting the molding principle of pellet feed loop molding machine. Therefore, the pellet feed molding equipment can not be used directly for processing biomass pellet, and people need to optimize the equipment. It was suggested that grading the straw was to adapt the different usages about feed and fuel.
