Embodiment 1

[0034] A kind of production method of ammonium oil explosive, comprises the following steps:

[0035] Step 1: Get 95 parts of the following components ammonium nitrate according to the mass fraction, and get raw materials in 5 parts of diesel oil;

[0036] Step 2, putting the ammonium nitrate into a grinder for crushing;

[0037] Step 3, putting the diesel oil into the oil phase tank and transporting it to the bottom of the grinder through the oil phase tank delivery pipe;

[0038] Step 4, mixing the diesel oil sprayed out through the nozzle of the delivery pipe of the oil phase tank and the crushed ammonium nitrate through the mixer, and transporting them to the inlet of the charging machine;

[0039] Step five, discharging, packing and sealing.

[0040] In step 2, the granularity of ammonium nitrate after crushing is 60 mesh, and the crushing machine is a double-roller crushing machine.

[0041] In step 3, the delivery amount of the diesel oil is metered by the oil phase ...

Abstract

The invention relates to a production method and a device of anfo explosives, which are characterized in that: the production method comprising the following steps of: adopting the anfo explosives which are formed by mixing crushed ammonium nitrate and diesel, taking the material, crushing, mixing, discharging, packaging, sealing and the like. The production method of the anfo explosives has a simple process, and is easy to operate and achieve streamline production; and the production device drastically improves production safety of the anfo explosives, saves labor resources and energy, is clean and safe, is easy to process and product, and reduces production cost.

Description

technical field [0001] The invention belongs to the field of chemical production, and in particular relates to a production method and equipment for ammonium oil explosives. Background technique [0002] Ammonium oil explosive refers to a powdery or granular explosive mixture composed of ammonium nitrate and fuel oil, which is mainly suitable for open-air blasting projects without the risk of methane and mine dust explosions. Ammonium oil explosive has the advantages of moderate explosive power and safe production. It is suitable for use in anhydrous blastholes, and has a large market use and demand. [0003] At present, the methods used to produce ammonium oil explosives and the production equipment used all have relatively large potential safety hazards. The production process requires high-temperature heating, finely crushed mixing, and the production equipment is complicated, and the production cost is high. A certain degree of waste is caused, which hinders the develop...
