Description

Technical Field

[0001] The utility model relates to the technical field of magnesia-lime brick raw material mixing, in particular to a mixing device for processing magnesia-lime brick raw materials which can be evenly mixed. Background Art

[0002] Magnesia-lime brick is an important refractory material with excellent high temperature resistance, slag resistance and other physical properties. It is widely used in refining equipment such as AOD furnace, VOD furnace and LF furnace. In the production process of magnesia-lime brick, mixing equipment is needed to stir and mix various raw materials to ensure the uniformity of the raw materials, crushing effect, parameter adjustment and production efficiency, thereby improving the overall performance and quality of the subsequent production of magnesia-lime brick.

[0003] The larger particles or agglomerates in the existing raw materials for magnesia-lime bricks are difficult to fully contact and mix with other fine particles during the mixing process, which will lead to uneven mixing. For example, a raw material stirring and mixing device for the production of building bricks and tiles disclosed in the announcement number CN215094592U does not have the function of fully crushing the raw materials. When the mixing device processes uncrushed raw materials, it may take longer to achieve the desired mixing effect, which not only increases the production cycle, but also leads to uneven distribution of internal components in subsequent brick processing, thereby affecting its physical and chemical properties.

[0004] Therefore, it is necessary to invent a mixing device for processing magnesia-calcium brick raw materials that can be evenly mixed to solve the above problems. Utility Model Content
