Description

Technical Field

[0001] The utility model relates to the technical field of magnesium oxide production, in particular to a feeding device for calcining magnesium oxide. Background Art

[0002] Magnesium oxide is an inorganic chemical widely used in applications such as rubber, tires, and fiberglass. It is typically obtained by calcining magnesium hydroxide at temperatures between 700 and 850 degrees Celsius. This high temperature poses significant risks to operators, including burns and heat radiation. By mixing and calcining two types of magnesium hydroxide, a product with more stable performance and a more cost-effective solution can be obtained.

[0003] A magnesium oxide calcining feeding device is required in the magnesium oxide production process. In the prior art, magnesium hydroxide is very easy to absorb moisture in the air in the humid summer, resulting in product agglomeration and material stickiness. At the same time, magnesium hydroxide has a small particle size and a large surface tension. Before entering the calcining device, it is easy to cause material bridging, material discharge blockage, and discontinuous discharge, thereby affecting production efficiency. In terms of material transportation and distribution, there are problems such as low efficiency and poor uniformity, resulting in unstable calcination quality, affecting the production efficiency and product quality of magnesium oxide, and failing to meet production needs. Therefore, a magnesium oxide calcining feeding device is proposed to solve the above-mentioned problems. Utility Model Content
