Water slurry is a mixture made by adding a certain amount of additives to pulverized coal and water. Improper handling of coal water slurry during storage, transportation and application will cause soft precipitation and stratification to destroy its combustion characteristics.


When the single screw pump is working, the volume of the pump cavity is constant, the medium is hardly stirred in the pump, and it is also conducive to the “maturation” of the slurry. So far, it is still a more ideal type of coal water slurry transportation.
