    Abstract: Packaged sticks of stiff slurry blasting composition are produced by apparatus and method which (1) form a slurry of pumpable consistency by blending together a solution of inorganic oxidizer salts, such as ammonium nitrate, sodium nitrate and/or others with solid fuels and/or sensitizers, (2) pump the slurry, by means of an air-diaphram pump, through a hollow mandrel or tube, (3) package the extruded slurry as it emerges from the mandrel by encompassing the composition in a packaging material of tubular shape, which is either surrounding or sealed around the extruded slurry, (4) performing a tying and cutting operation between successive lengths to form sticks as they are filled, and (5) conveying the filled sticks to packaging or delivery, all in a continuous process.
