  • Method for controlled refining of explosive compositions
    Patent number: 5841055
    Abstract: An apparatus for the controlled refining of an emulsion explosive composition is shown. The apparatus includes a pump for pumping the pumpable explosive composition, a conduit for transporting the explosive composition away from the pump, and a refining or shear valve located in the conduit. Also provided is control instrumentation which allows the amount of refining to be monitored. The preferred control instrumentation comprises a first pressure indicator located on an upstream side of said valve, the second pressure indicator located on the downstream side of said valve, and an adjustor associated with the valve to allow the valve to be adjusted to produce a predetermined pressure difference between the first and second pressure indicators.
    Type: Grant
