1. 物料容重:γ=0.2-1.8�?立方籲�br/>Material bulk density: γ=0.2-1.8t/m3
2. 温度: 物料温度t�?00度c
Temperature: Material temperature t�?00oC
3. 含水玆� 对于一般物料，不得使物料用手捏成团后不易松散，对于含水率认加后会加大粘着性和压给性的物料，不能使物料严重粘附刮版、�br/>Water ratio: For common materials, they should not be easily loose after squeezed into cluster by hand. For the materials that the adhesivity and press-feedbility would increase after add water ration, they should not be adhere to scraper badly.
4. 粒度: 物料的粒度与其硬度有关，粒度太大. 则不宜输�? 对物料粒度的要求见下表、�br/>输送物料的粒度(毫米)
Granularity: The materials� granularity is related to their rigidity, if the granularity is too high, it is not easy for transporting. The requirement of materials� granularity is as follows:
