Embodiment 4

[0022] The modifying agent that adopts among the embodiment 4 is the powder mixture that octadecylamine acetate and bentonite form, and its weight ratio is 1: 0.3; The composite oil phase that adopts is the mixture of Span-80 and A-type wax, and its The weight ratio is 1:50.

Embodiment 5

[0023] The modifying agent that adopts among the embodiment 5 is the powder mixture that octadecylamine sulfonate and bentonite form, and its weight ratio is 1: 1; The composite oil phase that adopts is the mixture of Span-80 and A-type wax, and its The weight ratio is 1:60.

[0024] The modifying agent adopted in embodiment 6 and embodiment 7 is a powder mixture composed of octadecylamine borate and bentonite, and its weight ratio is 1: 1; the composite oil phase adopted is Span-80 and A-type wax mixture with a weight ratio of 1:50.

Embodiment 8

[0025] The modifying agent that adopts in embodiment 8 is the powdery mixture that octadecylamine phosphate and bentonite form, and its weight ratio is 1: 1; The composite oil phase that adopts is the mixture of Span-80 and A-type wax, and its weight The ratio is 1:40.

[0026] The process step of concrete implementation is:

[0027] As shown in Figure 1. Put the ammonium nitrate 1 into the coarse crusher 2 for coarse crushing, and then transport it to the cam grinder 5 through the quantitative screw 3, and connect the hot air pipeline 4 between the quantitative screw 3 and the cam grinder 5, and connect the cam grinder 5 and the cyclone separator 7 They are connected to 6 with hot air pipes, before the modifier 14 is continuously added to the cam pulverizer 5, the air 11 passes through the fan 12, and the heat exchanger 13 forms hot air at 135°C, and enters the cam pulverizer 5 from the hot air pipe 4, and then transported to the cyclone Separator 7, the material coming out...

Abstract

The invention discloses a process for the continuous production of modified ammonium nitrate fuel explosive, which consists of comminuting ammonium nitrate, aeration-drying, charging modifier 0.1-0.5 wt% of the total raw material, then charging compound oil phase 2-8 wt% of the total raw material, 2-6% of wood powder and mixing, finally continuously grinding in a continuous oscillating ball grinder.

Description

technical field [0001] The invention relates to a method for ammonium oil explosives, in particular to a method for continuously producing modified ammonium oil explosives. Background technique [0002] The existing modified ammonium nitrate explosives are generally produced by a two-stage method, that is, high-temperature heavy weights are used to press the nitrate, and low-temperature medium or light weights are mixed. The heavy wheel mill relies on the rolling effect of the wheel mill and the heating of the chassis to complete the crushing, drying and modification of ammonium nitrate. After reaching the required process conditions, it passes through the second stage wheel together with the oil phase, wood powder or other materials. Milling and blending into finished products. The disadvantage of this process method is that continuous production cannot be realized, the production efficiency is low, the labor intensity is high, and there are certain potential safety hazard...
