Global Coal amp; Mining Pvt. Ltd.

The coal and water is fed in the cylindrical portion of the barrel which rotates at certain predetermined speed. The spiral inside the barrel creates waves in the water in which the pulsation of coal takes place. The lighter coal moves with the top layer of the wave and discharged at the conical end as low ash coal or clean coal.
