Puffed borax as an agglomerating aid

摘要

According to the invention, in a process for agglomerating a mass of particulates containing hydratable or hydrated inorganic salts wherein the particulates are sprayed with a silicate solution to form agglomerates and the resulting agglomerates are subjected to an aging/drying step to allow hydration equilization and excess water evaporation, the improvement comprises replacing a portion of the particulates with puffed borax as an agglomerating aid to minimize aging/drying time.
