Abstract
A method of forming a deicer composition. The deicer composition comprises of a mixture of halide salts of alkali and alkaline earth metals which are then pan agglomerated to form a low bulk density easily dissolvable but free flowing agglomerate composition.
Claims5
A method of forming a deicer composition, said method comprising:
- forming a mixture of halide salts of metals selected from the group consisting of alkali and alkaline earth metals;
- grinding said mixture of salts to a fine powder, and pan agglomerating said mixture using a magnesium chloride salt solution as an agglomerating fluid, and conventional removal of moisture with hot air to form dried, uniform, homogenous agglomerates.
A method of pan agglomerating a deicer composition mixture using a magnesium chloride salt solution as the agglomerating fluid, said method comprising:
- forming a mixture of halide salts of metals selected from a group consisting of alkali and alkaline earth metals;
- grinding the deicer composition mixture to a fine powder of particle size 80 to 100 mesh;
- placing size reduced particulate deicer composition mixture in a pan agglomerator;
- spraying an agglomerating fluid magnesium chloride salt solution having a salt concentration from 15 to 35 on said particulate deicer compositions;
- drying the resulting composition with hot air to form dried, uniform, homogenous agglomerates, substantially spherical in shape which are highly porous and which have a bulk density from about 30 pounds per foot cube to about 60 pounds per foot cube.
