| 中文摘要: |
| 基于对水泥的密相气力输送试验,研究了栓压、栓速、栓长之间的关系.研究结果表明,栓速一定时,栓压随栓长的增加而增加;栓长不变时,栓压随栓速的增大而增大;实际工程中可取料气速度比为0.9. |
| 英文摘要: |
| Base on the dense phase pneumatic conveying experiment of cement, the relations among plug pressure, plug velocity and plug length were investigated. The result showed,with a given plug velocity, plug pressure increased when plug length increased and,with a given plug length,plug pressure and plug velocity have the same relation. The ratio of solid and gas velocity may be assumed to be 0.9 in industrial application. |
