[0002] Magnesium oxide is an important industrial raw material, widely used in industrial chemical and building materials industries. When preparing magnesium oxide, magnesium ore and slaked lime are calcined at high temperature to form magnesium acid, and then magnesium oxide is obtained after calcining the magnesium acid. After the magnesium oxide is crushed, screened and packaged, it is made into magnesium oxide powder. Dust removal equipment is required when crushing and screening magnesium oxide. This type of dust removal equipment is used to ensure that not too much powder will float into the air during the processing of magnesium oxide, and also to ensure a healthy working environment for workers.
