Description

Technical Field

[0001] The utility model relates to the technical field of low-dust screening structures, in particular to a low-dust screening structure for a magnesite conveying device. Background Art

[0002] Magnesite is a magnesium carbonate mineral, which is the main source of magnesium. When a solution containing magnesium acts on calcite, calcite will turn into magnesite, so magnesite also belongs to the calcite family. Rocks rich in magnesium will also change into magnesite. Magnesite often contains iron, which is the result of iron or manganese replacing magnesium. Magnesite is white or grayish white with a glassy luster. Iron-containing magnesite will appear yellow to brown. If it shows crystals, it is granular, and if it does not show crystals, it is blocky. In addition to refining magnesium, magnesite can also be used as a refractory material and for the preparation of magnesium compounds. In the process of magnesite processing, it needs to be transported first, and a screening structure needs to be set at the end of the conveying device for the final screening. However, the current magnesite conveying device uses a screening structure for dust removal, which is not good, resulting in a large amount of dust during the screening process. For this reason, we propose a low-dust screening structure for magnesite conveying devices. Utility Model Content
