Abstract

This application relates to the field of explosives production technology, and in particular to a granular ammonium nitrate (AM) explosive production line and its production method equipped with an ammonium nitrate long-range conveying device. The production line includes a feeding workshop, a mixing workshop, and a packaging workshop arranged sequentially at intervals. The feeding workshop is equipped with a closed long-range pneumatic conveying mechanism, a feeding hopper, an ammonium nitrate screw conveyor, and a vertically arranged bucket elevator. The mixing workshop is equipped with a double-screw mixer, a first quantitative screw conveyor, a second quantitative screw conveyor, and a substrate cart. A finished product screw conveyor is also installed between the mixing workshop and the packaging workshop. The packaging workshop is equipped with a weighing bagging machine, a weighing sewing machine, a bag pushing machine, and a double-track belt conveyor. The granular AM explosive production line and its production method equipped with the ammonium nitrate long-range conveying device of this application require relatively low initial investment. The entire production process is continuous, and after packaging, automatic weighing and sorting of qualified products can be achieved, which is beneficial for the efficient and continuous production of granular AM explosives.
