  • Patent number: 4142928
    Abstract: A method and apparatus for the production of explosive slurry composed of liquids containing fuels and oxidizing agent and under circumstances solid constituents and sensitizers, the state of aggregation of the slurry being controlled by the addition of thickening agents. The liquids are charge-wise mixed with the fuel and/or oxidizing agents, gelling agents and other constituents known in the art. From this batch or batches the product is then formed into a continuous, metered material flow into which a crosslinking agent is injected at a continuous and precisely controlled rate. Provision is also made for continuously and precisely injecting gassing and sensitizing agents. The crosslinking agent, and other agents if used, is/are uniformly distributed in a connecting, subsequent continuous mixing process before the stiffening material flow is fed to a continously operating cartridging machine after a thickening time which is controllable corresponding to the viscosity requirements of the cartridging process.
