Description

Technical Field

[0001] The utility model relates to the technical field of magnesite crushing, in particular to a magnesite circulating screening and crushing 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 be transformed into magnesite. Therefore, magnesite also belongs to the calcite family. Rocks rich in magnesium will also turn 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 crystals appear, it is granular. If no crystals appear, it is blocky. In addition to refining magnesium, magnesite can also be used as a refractory material and for the preparation of magnesium compounds. Magnesite needs to be crushed after mining.
