Light burned magnesium powder is an important refractory material

Light burned magnesium powder is an important refractory material. Light burned magnesium oxide powder is a material with moderate alkalinity and chemical activity, which is not only used as a refractory material and cementitious material, but also in other industrial fields. In addition, the development of slag splashing and furnace protection skills in converters has further expanded the application scale of lightly burned magnesium oxide powder. At present, the slag splashing and furnace protection skills are mostly applied after lightly burned magnesium oxide powder is formed into balls, including lightly burned magnesium oxide powder balls, lightly burned magnesium oxide balls, carbon containing lightly burned magnesium oxide balls, and carbon containing calcium containing lightly burned magnesium oxide powder balls. Light burned magnesium oxide powder, abbreviated as light burned magnesium powder, is a type of active magnesium oxide obtained by calcining magnesite, brucite, and magnesium hydroxide extracted from seawater or brine at around 800-1000 ℃. Light burned magnesium powder is a light yellow or light brown powder with a particle size mostly below 100 mesh. The crystals of periclase are very small, and the density of light burned magnesium balls is prepared by adding 80% of light burned magnesium powder to 2O water, placing it in a mixer for rolling, stirring, and mixing for 15-20 minutes to form a mixture. The product is then transported by a belt conveyor to the ball pressing mechanism to prepare the product, and then stacked. The finished product of lightly burned magnesium balls is dried in the dark for 48 hours to form strength and ready for sale.

The necessity of improving the production process of lightly burned magnesium balls

After years of production practice, our factory has produced light burned magnesium ball products according to the above preparation process, and the quality of the products has the following problems.

1) The sphere is loose. Low density, low strength, and easy to break. Especially during loading, unloading, transportation, compression, and falling, the sphere is prone to breakage.

2) Low ball formation rate. After being processed by a ball press machine, half of the material is a product and the other half is powder particles. The powder particles need to be manually returned to the ball press machine for further processing.
