Combining the advantages of both ANFO and emulsion explosives, this explosive demonstrates superior performance in a variety of environments, including dry and wet blastholes. With the continuous advancement of blasting technology and the increasing complexity of field operations, the application scenarios of industrial explosives are also expanding, placing higher demands on the production and packaging equipment of heavy ANFO.
