Due to residual moisture by a gravitational bound, the saturated vapor pressure is reduced in different degree, thus drying rate dropped significantly.
由于残余水分受到某种引力的束缚，其饱和蒸汽压则是不同程度的降低，因而干燥速度明显下降。

The experiment is to certify that dewatering middle particle size of coal slurry with gravitational dewatering obtain standard moisture of the commercial coal.
