What is Roller Hearth Kiln
Roller hearth kiln is a type of continous roller hearth furnace for various sintering industry uses. It was once used for sintering of building ceramics, sanitary ceramics, and daily-use ceramics. The New roller material-recrystallized silicon carbide roller increased the temperature to 1200℃ or higher, with upgraded design and manufacture, it is ideal for sintering lithium battery materials, rare earths, magnetic materials, electronic powders, and electrical ceramic parts.

Structure Of Roller Hearth Kiln for Lithium Battery
- Feeding Section: Raw materials such as lithium battery cathode and anode materials and electrolytes enter the kiln via a conveyor belt. pre-treat, including screening and weighing are crucial to ensure quality and stability.
- Preheating Section: Raw materials undergo a gradual temperature increase. This section is to remove moisture, volatiles, and other impurities from the raw materials to prepare them for the subsequent sintering process.
- Sintering Section: Raw materials undergo a high-temperature and high-pressure process, which causes the material particles to bond together, forming lithium-ion battery cathode and anode materials with specific mechanical strength and electrochemical properties. The temperature in the sintering section typically ranges from 1000℃ to 1300℃, while the pressure depends on the specific production process.
- Cooling Section: Cool section prevents the raw materials from cracking due to thermal expansion and contraction, and it also enhances the mechanical strength and electrochemical properties of the materials.
- Discharge: Sintered products are conveyed out of the kiln, ready for the next processing step.
