2 Slurry dewatering This step includes mixing the crushed coal with light oil containing a heavy oil, such as asphalt, in a slurry preparation tank to prepare the coal slurry. This is followed by putting the coal slurry into a slurry dewatering tank, and Detail By quotJCOALquot jointed by Kobe Steel Ltd with the partnership of Arutmin amp Bumi Resources.
Shallow tank, small diameter, low rotary speed, and low power consumption. Large clearance between impeller and stator, the stator is a cylinder with elliptic hole, and it is good for mixing and dispersing the gas and pulp. The height of stator is lower than impeller, pulp circulation volume is large, and it can be reached at 2.5 times of others.
