| 20090301618 | AMMONIUM NITRATE GRANULES - This invention relates to explosive grade ammonium nitrate porous granules. The granules are produced in a fluidized bed and are formed through a combination of layering and agglomeration to produce ammonium nitrate granules are spherical in shape, smooth, hard and dry and do not break down easily during handling. Ammonium nitrate granules of a specific size range and density can be prepared and the size range and density of the granules can be varied, depending on the application of the granules, and this has particular advantages in preparing granules for use in ANFO explosive compositions. | 12-10-2009 |
