ABSTRACT:
A process of drying moist or wet carbon particles in a series of tubular drying sections by electrical resistance heating where the current is introduced into the uppermost column of carbon particles through a graphite block positioned at the center of the top of the said column by attachment to a steel plate that includes a flat or a V-shaped shelf and that is provided with openings to allow the moisture to escape in the form of steam and wherein the dried or partially dried carbon may be fed into a second or into a sequential plurality of similar sections provided with similar graphite blocks similarly positioned.
