Method and apparatus for making aqueous slurry explosives are disclosed. The components of the aqueous slurry explosive are mixed in a variable speed rotary mixer where the speed of the mixer is determined by the sequence of addition of the explosive components. The explosive components generally comprise water; an inorganic oxidizing salt such as ammonium nitrate; organic liquid such as propylene glycol; organic solids such as sugar; air entraining agents such as microspheres; densifying agents such as hot ammonium nitrate solutions; thickening agents such as flours and guar gums and pH adjustors and self-explosives. The aqueous slurry explosive may be formed using ambient temperature water. The apparatus is particularly suited as a mobile unit for use in the field.
