Process for producing novel puffing nitramon

Abstract

The invention relates to a process for preparing novel expanded ammonium nitrate explosive, which comprises the following steps: water-phase dissolving and oil-phase melting; mixing two phases; expanding crystallization; realizing uninterrupted discharging through alternately converting vacuum cavities; mixing expanded explosive with a functional additive which is subjected to measurement after a product is dropped into a cool mixed spiral through a feeding bin; dropping a prepared semifinished product of the expanded explosive into a suspension conveyer through a spiral conveying device; and conveying the semifinished product to a filling package workshop by the suspension conveyer for explosive filling to obtain a finished product of the expanded ammonium nitrate explosive through package. The invention is the process for preparing the expanded ammonium nitrate explosive with safety and environmental protection, zero discharge of pollutant, small online explosive amount, high operating safety and high automatic control.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of civil explosives, and relates to a preparation process of a novel expanded ammonium nitrate explosive with the characteristics of less processing and manufacturing links, short process route, few process facilities, compact equipment layout, safety and environmental protection. 【Background technique】 [0002] At present, the existing expanded ammonium nitrate explosive preparation process includes continuous expansion and continuous drug mixing. The continuous expansion part of the process is carried out in the ammonium nitrate continuous expansion device. Condenser, continuous crystallizer, storage tank, and discharge screw. The continuous expansion part process includes water phase material crushing, dissolution, vacuum crystallization and material transportation. The continuous mixing part process is in the continuous mixing device of expanded ammonium nitrate explosive The expanded am...
