AI Technical Summary
Technical Problem
The fine crystalline reagents produced during the combination of nickel hydrazine nitrate are difficult to recover and process, leading to safety hazards and resource waste, and affecting the spreadability and detonation performance of nickel hydrazine nitrate.
Method used
Fine crystalline reagents are collected by vacuuming a transfer tank in the mother liquor and then granulated using a polymer binder. This optimizes the collection method, enables the recycling of the reagents, and improves their flowability and uniformity.
Benefits of technology
This method enables the recycling of finely crystalline nickel hydrazine nitrate, reduces safety risks and production costs, increases the yield of nickel hydrazine nitrate, and improves environmental performance.

Abstract
The application discloses a method for recycling fine-crystal medicaments generated in a nickel hydrazine nitrate combination process, and belongs to the field of initiating explosive devices and explosive medicaments, and comprises collection of the fine-crystal medicaments and granulation of the fine-crystal medicaments; under the premise that the combination process and device of the nickel hydrazine nitrate are not changed, the fine-crystal nickel hydrazine nitrate is recycled through the crystallization collection technology and the secondary granulation technology, the yield of the nickel hydrazine nitrate is improved, the waste gas produced in the waste medicament destruction process is eliminated, and the environmental protection is improved; the obtained granulated nickel hydrazine nitrate is detected by using a particle size analyzer, and the particle size distribution of the granulated nickel hydrazine nitrate is as follows: 20 mesh to 40 mesh particles account for about 30% of the product, 40 mesh to 60 mesh particles account for about 35%, and 60 mesh to 100 mesh particles account for about 35%, so that the particle size distribution is relatively uniform.
