Sustainable Mining and Metallurgy

Combined with the production characteristics of arsenic trioxide in a smelter, a new automatic packaging palletizing system was developed. The system consisted of bag-making packaging machine, conveying roller system, automatic stacking system, and control system. By introducing the composition, working principle of each component system, and the application effect，the system had the characteristics of accurate weighing, no dust in the packaging process, fast stacking speed and neat stacking type, and realized the integrated packaging mode of plastic inner packaging and iron drum outer packaging, as well as on-site unattended and remote production control, which greatly improved the production environment of toxic and harmful solid materials，and improved the production efficiency, so it was worthy of popularization and application in the same industry.
