Studies on the features of coal water slurry in a magnetic field

The features of coal water slurry was studied based on the cross test for Huainan washing coal and Beisu coal in the existence of magnetic field. The results indicate that the effects of coal, water and coal water slurry which were magnetized in the magnetical mug on the properties of coal water slurry varied at some degree. Compared with the blank coal water slurry sample, the surface viscosity and fluidity of coal water slurry of magnetized Huainan coal and Beishu coal is improved.
