Rare Earth Rotary Kiln
2025-08-30
1. Working Principle
( 1 ) Material Feeding : Rare earth oxide raw materials enter the inside of the drum through the feeding port. The materials can be in powder or granular form, depending on process requirements.
( 2 ) Rotational Movement : The drum is installed at a certain angle and slowly rotates under motor drive. This rotational movement causes the materials to continuously tumble inside the drum, fully contacting the high-temperature gas.
( 3 ) High-Temperature Calcination : Inside the drum, a combustion device ( such as gas or natural gas ) provides a high-temperature environment. The high-temperature gas contacts the materials, promoting chemical reactions such as dehydration, decarbonization, and oxidation of the rare earth oxides.
( 4 ) Calcination and Cooling : After calcination at high temperature, the materials are discharged from the other end of the drum and then enter the cooling system to avoid overheating that could affect product performance.
Technical Features
1. High-Efficiency Calcination : The combination of rotational movement and high-temperature treatment significantly improves calcination efficiency and shortens the production cycle.
2. Precise Control : The equipment is equipped with an advanced control system that can monitor the temperature and material status inside the drum in real time, ensuring the precision of the calcination process.
3. Environmental Protection and Energy Saving ; By optimizing the combustion device and heat exchange system, energy consumption and exhaust emissions are reduced, meeting environmental protection requirements.
2. Burner Selection
