ABSTRACT:
A method and apparatus are provided for the metered delivery of microbubbles, used for example, in the production of explosive compositions. Disclosed is a holding vessel with sufficient residence time to deaerate the microbubbbles with a level indicating device for sensing the quantity of microbubbles deposited therein, the outlet of the holding vessel communicating with a dual screw feed apparatus for delivering a constant volumetric flow of deaerated microbubbles from the holding vessel and a weigh-belt, upon which the microbubbles ae deposited as they exit the screw feeder, for providing a constant flow of microbubbles by weight for delivery to processing apparatus.
