Abstract
This composition consists of a coated composition of solid ice melting agents, abrasives and absorbents. The coated composition employs a coating of calcium chloride. The method of making the composition, also part of the invention, includes placing a solid ice melting agent such as urea, potassium chloride, sodium chloride and abrasives such as sand, gravel, cinders, and absorbents (i.e. calcined diatomaceous earth) into a mechanical stirring device; and spraying a measured amount of adhering solution on to the medium. This adhering solution may be made up, but not limited to, plain water, solutions of organic or inorganic solids with ice melting properties, etc. To this mixture is added a measured amount of powdered non-fully hydrated calcium chloride as a solid coatant. The non-fully hydrated calcium chloride by hydration forms a coating around the ice melt base. The resultant mixture is discharged from the mixer, screened and packaged.
