北京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 raw material with medium alkalinity and chemical activity. In addition to being used as a refractory and cementing material, light burned magnesium balls are also used in other industrial fields. In addition, the development of converter slag splashing protection technology has further expanded the application range of light burned magnesium oxide powder. At present, slag splashing furnace protection technology mostly uses light burned magnesia powder as balls, including light burned magnesia powder balls, carbon containing light burned magnesia sub balls, and carbon containing calcium containing light burned magnesia powder balls. Light burned magnesium oxide powder, abbreviated as light burned magnesium powder, is an active magnesium oxide obtained by calcining magnesite, brucite, and magnesium hydroxide extracted from seawater or brine at about 800 to 1000 ℃. Light burned magnesium powder is a light yellow and light brown powder, with particle size mostly below 100 meshes, and periclase crystals are very small. Leather sand price

The preparation of lightly burned magnesium balls involves adding 80% lightly burned magnesium powder to 2O water, placing it in a mixer for rolling, stirring, and mixing for 15 to 2 minutes to form a mixture. The product is then sent to the ball pressing mechanism through a belt conveyor to prepare the product, and then stacked. After 48 hours of drying in the shade and forming strength, the finished light burned magnesium ball is ready for sale.

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, squeezing, and falling, the ball is prone to breakage.

2) Low balling rate. After the raw materials are processed by the ball pressing machine, half are products and half are powder particles. The powder particles need to be manually returned to the ball pressing machine for further processing.

3) The user is not satisfied. The products sold contain a mixture of 20% - 35% small particles and powder particles, which users have repeatedly raised objections to.

4) The shape of the sphere is incomplete. Some are half balls, some are one-third balls, and some have missing corners, varying shapes, matt surfaces, and poor appearance.
