AI Technical Summary

Problems solved by technology

In smooth surface blasting, an explosive with high detonation velocity and low energy density is required. Through experiments, it is known that the powder explosive can meet the requirements after adding a certain proportion of additives. However, strong mechanical stirring cannot be used during the mixing process. Stirring will cause safety hazards such as explosion of powdered explosives during the mixing process. If the stirring is slow, it will lead to uneven mixing of explosives

Description

technical field [0001] The invention relates to the technical field of powdered explosives, in particular to a mixing device for powdered explosives. Background technique [0002] Due to its unique physical characteristics and certain water resistance, powder explosives are widely used in engineering blasting, special blasting, metal processing, tunneling and other projects. Powdered explosives have good fluidity, can be suitable for charging conditions in various shapes, and can also be mixed with a certain proportion of additives to adjust the performance parameters of explosives. In smooth surface blasting, an explosive with high detonation velocity and low energy density is required. Through experiments, it is known that the powder explosive can meet the requirements after adding a certain proportion of additives. However, strong mechanical stirring cannot be used during the mixing process. Stirring will cause safety hazards such as explosion of the powdered explosives ...
