More Information
Summary:The invention provides a method of making a sensitized flowable explosive by pumping a non-detonatable explosive base along a conduit having a mixer at its downstream end. Simultaneously lubricant liquid is pumped along the conduit while a flowable gassing agent is pumped along a separate flow line into the conduit, adjacent and upstream of the mixing device, where mixing of the constituents takes place to form a sensitized explosive. The invention also provides an apparatus (10) comprising an explosive base pump (22) connected to a conduit (46) provided witha mixer at its downstream end, a flowable gassing agent pump (28) and a lubricant liquid pump (30). The lubricant liquid pump (30) feeds into the conduit (46), and the gassing agent pump (28) feeds into a separate flow line (50) connected to the conduit (46) at the downstream end of the conduit upstream of the mixing device.
