US Patent 7276178 Pan agglomerated deicer composition using anhydrous raw materials

A method of forming a pan agglomerated deicer composition which avoids the need for a separate drying step. An agglomeration is accomplished by mixing at least partially anhydrous and halide salts of metals, grinding those into a fine powder, and pan agglomerating the fine powder with water or solutions of the halide salts which upon contact with the dry fine powder form fully hydrated and stable pan agglomerated salt mixtures which do not require drying.
