Patent ID: 7938920

Claim:
A method for making an explosive composition comprising: providing an end-to-end level blender; wherein said end-to-end level blender comprises: a mixer tank for holding at least two different materials that are to be blended together; a rotary structure for use in contacting at least two different materials within the mixer tank to facilitate the blending of the at least two different materials, the rotary structure having a first axis of rotation that is substantially parallel to a substantially planar upper surface of the materials that are to be blended when the mixing tank is substantially full of the materials and a first rotational portion for rotating about said first axis of rotation; and a drive for use in causing a first rotational portion to rotate about said first axis of rotation; using said end-to-end level blender to blend Heavy ANFO and an inert bulking and sensitizing additive comprising hulls of rice to achieve a high degree of homogeneity with little mechanical stress imparted to the Heavy ANFO and the inert bulking and sensitizing agent.
