METHOD OF PREPARATION OF EXPLOSIVE MIXTURES AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1998 - IPC

FIELD: mining; applicable in mineral opencast mining with use of explosive mixtures. SUBSTANCE: the offered method includes blending of granulated and liquid components in a preset ratio by gravitational method. In blending trajectory of motion of each particle of flow is multiply changed in direction due to combining of component trajectories into common trajectory. Introduced into flow of particles at upper level is diesel fuel, and at the lower level, water-oil emulsion. The device for embodiment of the offered method has vessels for solid and liquid components, blender with dispersing surface and liquid phase feeder. Blender has closing changeable plate with different area of calibrating holes and collecting surface whose dihedral angle amounts to 40-55 deg. EFFECT: higher efficiency. 3 cl, 1 dwg
