Abstract
A process is described for minimizing the sticky or tacky surface characteristics of free water-containing glass batch pellets so as to allow for the more expeditious handling of such pellets in further processing operations. Generally, this is effected by coating the pellets subsequent to their formation on a rotating disc pelletizer, the coating being done with a tumbling motion in a rotary drum member so as to form a substantially uniform surface coating on the pellets. The coating material is the same glass batch composition employed to produce the pellets.
