Magnesium Oxide Rotary Kiln Introduction

Magnesium oxide rotary kiln is the core equipment specially used for calcining magnesite (MgCO₃) or other magnesium-containing raw materials to produce magnesium oxide (MgO). The kiln cylinder is the heating part, which is made of high quality calm steel plate roll. It obtains high purity magnesium oxide by high temperature decomposition reaction (MgCO₃ → MgO + CO₂↑). Due to the special characteristics of calcination, the kiln generally adopts a variable diameter cylinder.

Magnesium oxide rotary kiln is widely used in refractories, building materials, chemical industry, environmental protection and other fields.

Magnesium Oxide Rotary Kiln Working Principle

Magnesium oxide rotary kiln mainly decomposes raw materials through high temperature calcination. The working process of magnesium oxide rotary kiln can be divided into nine steps: mineral separation, entry, sintering, artificial screening, inspection, mixing production, crushing products, inspection and storage.

First raw materials into the kiln, through the rotation of the kiln body to achieve the material fully mixed and react with each other. After calcination, cooling, grinding and molding. It is then mixed with ferrosilicon powder and fluorite powder. The magnesium is reduced and produced in large quantities in a reduction furnace at 1200 -1250°C and 1.33pa Vasco. Heat is transferred to the material by flame radiation, hot air convection and kiln brick conduction, and the material is moved forward through the kiln’s slopes and rotations.

Finally, the material passes from the kiln hood into the cooler. After a series of processes such as melt refining, ingot casting and surface treatment, finished magnesium ingots are produced.

Magnesium Oxide Rotary Kiln Advantages

• The advanced technology of magnesium oxide rotary kiln improves the quality of the material and enhances the wear resistance of the material.
• The magnesium oxide rotary kiln has high output per unit volume, and can increase the thickness of material layer and rotating speed, so that the material is heated evenly.
• Magnesium oxide rotary kiln has many advantages such as high heat circulation utilization, high thermal efficiency, low energy consumption, low production cost, etc. Its burner can make full use of the heat energy of the fuel.
• The rotary kiln is characterized by uniform heat transfer, and its internal trapezoidal plate and angle can make the materials receive heat evenly in the kiln, thus improving product quality.
