The size distribution of coal is considered to be small, when the medium concentration coalslurry is transported in the pipeline. The cost of preparation of slurry and dewatering cost are high.
在中浓度煤浆管道输送中，煤的粒度组成偏细，使制浆及脱水费用较高。

An idea of drag reduction by pre-stirring on pipeline transportation of highly loaded coal-water slurry is firstly proposed in this paper.
木文首次提出了高浓度水煤浆管道输送搅拌减阻的思想。

The pressure of viscous materials with high concentration such as coalslurry, paper pulp, waste mud in the transportation pipeline can't be measured by common pressure sensors.
