The results show that the specific energy increases as the pressure increases under the same initial density, but there is no marketable effect on density of briquette under increasing specific energy in tight compression.
在初始密度相同的条件下，随着压力增大，压缩比能增大，但在压紧阶段，压缩比能增加对提高棉秆的压缩密度效果不明显：在最大压力相同条件下，粒度越小或含水率越低，压缩比能也越小。
