Description

Technical Field

[0001] The utility model relates to the technical field of mining, in particular to a conveying device used for bauxite mining. Background Art

[0002] Bauxite actually refers to the general term for ores that can be used in industry, with gibbsite and diaspore as the main minerals. Bauxite is the best raw material for the production of metallic aluminum and is also the most important application field, accounting for more than 90% of the world's total bauxite production. The application fields of bauxite include both metal and non-metal. It is the best raw material for the production of metallic aluminum and is also the most important application field, accounting for more than 90% of the world's total bauxite production. Although the proportion of bauxite in non-metallic aspects is small, its uses are very wide. In the process of bauxite mining, since the diameters of the ores obtained are mostly different and the gap is large, they need to be screened, but the screening is usually carried out by a separate screening device, and the screening device is connected to the conveying device, and the bauxite is conveyed to the screening device through the conveying device, and then screened. Due to the split processing, the screening device and the conveying device both occupy a certain area, resulting in a large footprint of the device, which is inconvenient for bauxite processing. In addition, due to the split processing of loading, conveying, and screening, a lot of transportation time is wasted, which reduces the processing efficiency of bauxite. For this reason, we propose a conveying device for bauxite mining. Utility Model Content
