Problems solved by technology

[0004] However, since the wheel mill is a discontinuous production equipment, continuous automatic production of products cannot be realized, and the production efficiency is low and the labor intensity is high.
Special attention should be paid to the local heating and possible friction of the wheel mill. There are certain risk factors in the production process, which limits the popularization and application of modified ammonium nitrate explosives.

Embodiment Construction

[0019] The content of the present invention will be described in further detail below in conjunction with the drawings and the embodiments shown in the drawings. But they are not limitations of the present invention.

[0020] Two cam pulverizers 6,12 are installed in series for stand-by. Add 0.3% modifier 2 quantitatively into the packaging bag of ammonium nitrate 1, and put the mixture into the roller crusher 3 for coarse crushing. Use a magnet sieve 4 for iron removal and primary mixing, and then transport it to the primary cam pulverizer 6 for pulverization through the screw quantifier 5; then enter the secondary cam pulverizer 12 through the ammonium nitrate drying pipeline 11 for secondary pulverization. After the air 7 passes through the fan 8 and the heat exchanger 9 to become hot air at 130°C, it enters the ammonium nitrate delivery pipes 11 and 14 through the hot air pipe 10 through the primary cam pulverizer 6, and enters through the hot air pipe 13 through the seco...

Abstract

The invention adopts two cam pulverizers to be installed in series, and the two pulverizers are connected by an ammonium nitrate drying pipeline, and the hot air enters the ammonium nitrate drying pipeline through the two cam pulverizers, and completes the process of being transported to the cyclone separator. Heating and modification of ammonium nitrate. The ammonium nitrate separated by the cyclone separator automatically enters the ammonium nitrate discharge screw, adds the oil phase and wood powder, and is transported by the feed screw to the continuous ball mill mixer for grinding and mixing to obtain the desired product. Reaching the continuous production mode instead of the discontinuous wheel mill production mode.

Description

technical field [0001] The present invention relates to the production method of ammonium nitrate explosive, more specifically, a kind of method about the continuous production of modified ammonium nitrate explosive. Background technique [0002] The non-stepping of powder industrial explosives is the technical development direction of the civil explosives industry. However, at present, many mainstream products of non-stepping explosives have to re-establish production lines. Ladderless explosives production line is a huge waste of money and time. [0003] The existing modified ammonium nitrate explosive is a powdery stepless explosive developed under the process conditions of the high-temperature heavy-weight wheel mill. The main production equipment is composed of a modified wheel mill and a mixed wheel mill. Ammonium nitrate and modified The additive is manually added to the modified wheel mill, and the ammonium nitrate is pulverized, heated and m...
