In the rapid development of the new energy lithium battery industry, the high-temperature carbonization and calcination of artificial graphite anode materials, as the core link determining product quality and production cost, imposes strict requirements on thermal equipment. Xi'an Ruitai Building Materials Technology Co., Ltd. (Brictec), relying on advanced European thermal technology and years of experience in tunnel kiln baking temperature control, has been deeply engaged in the research and application of tunnel kiln combustion systems. From a traditional tunnel kiln baking thermal expert in the building materials field, it has highly adapted to the lithium battery anode material tunnel kiln combustion system supplier, providing customized, efficient, stable and cost-saving tunnel kiln solid burner solutions for the carbonization and baking of lithium battery artificial graphite precursors.

I. Enterprise Strength: From a Benchmark in Building Materials Thermal Engineering to Service for Lithium Battery Pyrolysis

Xi'an Ruitai Brictec was established in 2011. It integrates Italian senior engineers and domestic top technical experts, integrates European cutting-edge thermal engineering concepts with mature tunnel kiln burner manufacturing systems, and has constructed a complete industrial chain from research and development, design, manufacturing to full life cycle services.

The company has been deeply engaged in tunnel kiln thermal engineering equipment and drying process fields for over a decade. Its core technologies cover efficient combustion of multiple fuels, precise temperature control, atmosphere protection, and furnace pressure control, etc. Its products have expanded from the traditional building materials sintering field to high-end new materials such as lithium battery negative electrode materials, carbon materials, and new energy mineral materials. Especially in the high-temperature carbonization and calcination scene of artificial graphite negative electrodes, it has formed unique technical barriers and application advantages.

With over 30 countries and regions' project implementation experience worldwide and a local service network, Brictec has become a trusted core partner of lithium battery enterprises in both domestic and international markets for tunnel kiln burners. With the core values of "leading technology, stable and reliable, cost reduction and efficiency improvement", it helps negative electrode material production enterprises break through thermal engineering bottlenecks.

II. Core Technology: Tailored for negative electrode carbonization, with five technological advantages leading the industry

To meet the carbonization and calcination requirements of artificial graphite negative electrode materials for high temperature, continuous stability, low consumption and environmental protection, the Brictec tunnel kiln burner breaks through traditional technical limitations and creates five core technological advantages, perfectly adapting to the negative electrode production process: 

Efficient Combustion Technology: High fuel utilization rate, significant cost reduction

Adaptable to various fuel characteristics, achieving full and stable combustion of fuels: Compared to traditional burners, fuel consumption is reduced by 12%-18%, reducing the maximum variable cost of negative electrode production at the source;

Precise control of air-fuel ratio, eliminating "overheated air combustion", with 100% of the heat applied to the material calcination, without any ineffective energy consumption;

Adaptable to various types of fuels, able to switch flexibly according to energy prices, avoiding risks associated with fluctuations in a single fuel price. 

2. Precise Temperature Control Technology: Uniform Temperature Field Ensures Batch Stability

Equipped with a PLC fully automated closed-loop temperature control system, which is in real-time联动with the kiln carriage speed and temperature sensors：

Achieve precise temperature control throughout the entire kiln section， linear adjustment， uniform temperature， ensuring uniform carbonization of the negative electrode material and consistent performance；

Unattended intelligent adjustment， replacing manual operation， avoiding process fluctuations caused by human errors， and improving product qualification rate. 

3. Long-life Design: Continuous operation, reduced operation and maintenance costs

For the high-temperature and complex working conditions of the negative electrode carbonization process, a high-temperature-resistant alloy composite burner is adopted:

The continuous operation lifespan is 2-3 times that of ordinary burners, significantly extending the replacement cycle and reducing equipment procurement and maintenance frequencies;

Standardized and quick-disassembly designs for wear parts shorten the replacement time to 1-2 hours, avoiding production losses caused by long-term shutdowns; The fully sealed structure reduces fuel waste and lowers the loss during the roasting process, thereby indirectly achieving cost reduction and efficiency improvement.

III. Full-process Service: Beyond equipment, also offers systematic thermal engineering solutions 

Brictec is well aware that the stable and efficient production of lithium battery negative electrode carbonization cannot be achieved without the deep integration of equipment, process and services. Based on its over ten years of experience in tunnel kiln burner thermal engineering projects, the company provides customers with full lifecycle services ranging from scheme design to long-term operation and maintenance: 

Customized solution design 

Based on the customer's negative electrode material production capacity, process parameters, fuel type, and kiln specifications, a one-to-one customized burner system solution is provided to ensure perfect matching with the entire carbonization production line and achieve the optimal thermal efficiency. 

2. Equipment Manufacturing and System Integration 

Independently develop and manufacture the core combustion equipment, equipped with a fully automatic control system, kiln protection system, and waste heat recovery system, achieving seamless integration and intelligent linkage of the combustion system with the tunnel kiln, kiln car, and conveying line. 

3. Installation, commissioning and process optimization 

The professional technical team provides on-site installation and commissioning services, optimizing combustion parameters, atmosphere parameters and temperature control parameters to ensure that the production line can reach full production capacity quickly and operate stably. At the same time, they also provide process training for customers.

IV. Project Case: Empowering Lithium Battery Anodes, Achieving Remarkable Results
