Description

Technical Field

[0001] This utility model relates to the technical field of fused magnesia production equipment, specifically to a fused magnesia raw material briquetting device with screening and crushing functions. Background Technology

[0002] Fused magnesia is a high-grade refractory material made from high-quality magnesite, lightly calcined magnesia powder, or seawater magnesia through high-temperature melting in an electric arc furnace. Due to its high purity, high density, low impurities, high temperature resistance, and good chemical stability, it is widely used in metallurgy, building materials, chemical industry, and other fields.

[0003] In the production of fused magnesia, pelletizing the raw materials can form loose raw materials into pellets with a certain strength and shape, increasing the bulk density of the raw materials. This is beneficial for uniform heating and melting in the furnace, thus improving production efficiency. In addition, the formed pellets can reduce dust from the raw materials during transportation and smelting, reducing environmental pollution and improving the production environment.

[0004] Existing fused magnesia raw material briquetting equipment cannot screen and crush agglomerated raw materials during the production process. Agglomerated raw materials directly enter the briquetting stage, which leads to uneven briquetting density and insufficient strength, thus affecting product quality. It also easily causes wear and tear and failure of the briquetting equipment, reduces production efficiency, and increases equipment maintenance costs. Utility Model Content
