A new powdered ammonium nitrate explosive Powdered Emulsified Explosive is presented. It possesses the unique structure of oxidizer phase-in-oil, which makes it has the remarkable advantages of both Emulsion Explosive and powdered explosive. In this paper, the formulation and the preparation technology of the explosive are expounded, the property characteristics of the explosive is analyzed. It have wide prospects of application.
The mobile factory of preparation emulsion MEF includes preparation of oil and water phases; transportation of phases; batcher; continuous emulsify and automatic control. has high mobility and convenience in operation. Received emulsion can be used for chinks of any diameter. The combined application together with charging by machine such as BCJ can satisfy the requirement of different explosive works. Application has good prospect in the future.
Local charging machine of emulsion explosives, design features and composition of BCJ series mixing and charging machine for EBVs are considered. A critical analysis of the design and the possibility of its application is given. This series of mixing and charging machine (MCM) meets the requirements of different explosive technologies and is very promising.
