Technical Field

[0001] The utility model belongs to the technical field of magnesium oxide production, and particularly relates to a material mixing device for magnesium oxide production. Background Art

[0002] Magnesium oxide mixing and stirring is commonly used in many fields and applications. In the metallurgical process, magnesium oxide mixture can be used as the raw material of refractory materials. By stirring and mixing magnesium oxide with other materials, refractory materials with high temperature heat resistance can be prepared. They are used in high temperature furnaces, high temperature railway tunnels and other places. However, when purchasing magnesium oxide raw materials, a lot of magnesium oxide will clump. If it is directly put into it when mixing is needed, the mixing effect will be poor.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology makes it so that when purchasing magnesium oxide raw materials, a lot of magnesium oxide will clump. When mixing is required, if it is directly put into it, the mixing effect will be poor. However, when the magnesium oxide mixing equipment is mixing magnesium oxide, there is no device for crushing and screening the magnesium oxide. In this way, when the magnesium oxide blocks are mixed with other raw materials, the magnesium oxide blocks will be mixed unevenly with other raw materials, so that there will be problems with the subsequent mixed products. Therefore, a mixing device for magnesium oxide production is specially proposed to solve the above problems. Utility Model Content
