Sustainable Mining and Metallurgy

To address issues that plague the overhead crane for aluminum hydroxide bins during the alumina production process, including difficulty in monitoring material levels and equipment status and properties, the inhospitable working environment of the loading site, extended and intense working hours of the crane operator, low operation efficiency and great electricity consumption, this article first analyzed the patterns of the operation process, then proposed an IOT-based unattended system, which integrated laser scanner for bin level sensing and overhead crane movement control techniques, to upgrade the system and realize unattended crane operation.
