Every instance of waste — from fuel consumption and equipment wear to finished-product scrap — accumulates into a heavy operational burden. Brictec tunnel kiln burners are specifically engineered for the high-temperature carbonization conditions of artificial graphite anodes. With five core cost advantages, they deliver visible, quantifiable cost reduction and efficiency gains for lithium battery anode producers, while balancing economic performance and regulatory compliance, helping enterprises seize a decisive cost advantage in fierce competition. Core Advantage One: High-Efficiency Combustion – Directly Reducing Fuel Costs Fuel expense is the largest variable cost in anode carbonization production. Traditional burners suffer from incomplete combustion and low thermal efficiency, resulting in substantial energy waste. Brictec tunnel kiln burners adopt fully pre-mixed, enclosed, automated high-efficiency combustion technology tailored to the combustion characteristics of low-cost solid fuels, achieving significantly higher fuel utilization and reducing consumption at the source: Adaptable to a variety of low-cost solid fuels and mixed fuels, allowing flexible switching based on regional energy prices and supply conditions to lock in fuel cost advantages and mitigate risks from single-fuel price volatility; Precise temperature control prevents overheating and eliminates ineffective energy consumption caused by “over-temperature idling,” ensuring every unit of heat is applied directly to material calcination and maximizing fuel value. Core Advantage Two: Long-Service-Life Design – Significantly Reducing Equipment Operation & Maintenance Costs Frequent shutdowns for maintenance and component replacement not only incur direct procurement costs but also cause production losses due to downtime — a “hidden cost killer” for anode manufacturers. Targeting the harsh conditions of solid-fuel combustion, our burners feature high-temperature-resistant composite heads and a modular structure, perfectly suited to complex combustion environments and greatly enhancing equipment stability: Continuous operating life is 2–3 times longer than conventional burners, substantially extending replacement intervals, reducing procurement frequency, and lowering core component replacement costs; Standardized wear-part design shortens replacement time to just 1–2 hours, preventing prolonged downtime that delays orders and wastes capacity, while ensuring 24-hour continuous production line operation; Fully sealed structure minimizes heat leakage inside the kiln, reduces wear on the kiln insulation layer, and decreases abrasion from combustion residues, indirectly extending the overall service life of the tunnel kiln and lowering total equipment O&M costs. Core Advantage Three: Zero-Leakage Oxygen Protection – Eliminating Finished-Product Scrap Costs at the Source Oxidation of anode materials at high temperatures is the “cost black hole” most feared by enterprises. Brictec burners employ a fully sealed, leak-proof structure to safeguard material quality: Effectively isolates impurities and air infiltration during combustion, raising the yield rate of finished anode materials and completely eliminating extreme risk; Reduces rework and sorting costs caused by quality fluctuations, ensuring every batch meets the performance standards of downstream battery manufacturers and preventing capital tie-up from scrap accumulation; Avoids brand damage to customers caused by oxidation or excessive impurities, protecting long-term market reputation and lowering brand maintenance costs. Core Advantage Four: Automated Interlocking Control – Reducing Labor and Management Costs Traditional burners rely on manual flame adjustment, especially with solid fuels, where regulation is difficult and prone to error. This not only lowers efficiency but also introduces process fluctuations that increase management complexity. Brictec burners support full PLC automated control, fully adapted to solid-fuel combustion process requirements: Real-time linkage with kiln car speed and temperature sensors enables unmanned, precise temperature control and combustion load adjustment, cutting 2–3 on-site operator positions and significantly reducing labor and management expenses; Stable process parameters ensure batch-to-batch consistency, reducing the frequency of quality inspections and lowering management costs for quality testing and data traceability. Choosing Brictec tunnel kiln burners is not merely purchasing a set of high-efficiency equipment adapted to artificial graphite anode carbonization — it is introducing a sustainable cost-optimization solution for the entire anode carbonization production process. By balancing combustion efficiency, equipment stability, and economic value, Brictec enables enterprises to achieve “cost reduction without quality compromise, efficiency gains with quality improvement,” building a solid cost barrier in the highly competitive new-energy market.

The auger shaft is responsible for transmitting most of the torque generated during operation and for conveying clay materials forward under pressure. Therefore, its operating condition directly affects the forming quality of green bricks as well as the operational stability of the equipment. During long-term production, due to complex raw material conditions and variations in equipment load, bending or deformation of the auger shaft is a relatively common mechanical problem. If not addressed promptly, it may lead to abnormal equipment operation, mechanical damage, or even production shutdown. Based on practical maintenance experience in the brick and tile industry, this paper introduces a practical on-site correction method that does not require disassembling the extruder, which is especially suitable for small and medium-sized brick factories with limited maintenance capability. 1. Structural Characteristics of the Extruder Auger Shaft The auger shaft is a key transmission component inside the extruder and has the following structural characteristics. High Torque Transmission During the extrusion process, the auger shaft continuously transmits mechanical power while pushing the clay material toward the die head. Tangential Key Slots In order to mount the auger blades, the shaft is usually designed with two tangential keyways. Although this structure facilitates blade installation, compared with a solid shaft of the same diameter, its bending strength and torsional strength are relatively reduced. Material and Manufacturing Characteristics In traditional brick machinery manufacturing, due to equipment limitations, many auger shafts do not undergo quenching and tempering heat treatment. According to general mechanical manufacturing standards, transmission shafts that do not undergo proper heat treatment tend to have lower fatigue resistance and impact strength, which increases the possibility of deformation during long-term operation. 2. Main Causes of Auger Shaft Bending In practical brick production, the bending of the extruder auger shaft is mainly caused by the following factors. 2.1 Variation in Raw Material Properties Raw material conditions vary significantly among different brick factories, such as: Differences in plasticity index Fluctuations in moisture content Unstable particle size distribution These factors cause significant fluctuations in the operating load of the extruder, resulting in periodic alternating torque on the auger shaft. 2.2 Poor Raw Material Processing If the raw material is not properly processed, it may contain: Stones Metal fragments Hard impurities When these foreign objects enter the extruder, they generate instantaneous impact loads, which may cause bending or even twisting of the auger shaft. 2.3 Changes in Product Specifications When producing different types of bricks, such as: Perforated bricks Insulated hollow blocks Standard clay bricks the extrusion pressure varies significantly, which imposes different levels of mechanical load on the auger shaft. 2.4 Long-Term High Load Operation Extruders are typically continuous production equipment. Long-term operation under high load conditions accelerates the fatigue deformation of the auger shaft. 3. Typical Symptoms of Auger Shaft Bending When the auger shaft becomes bent, the following phenomena usually occur: Significant increase in die head oscillation Fluctuation in extrusion pressure Local friction between the auger and the barrel liner Increased vibration and noise of the equipment In severe cases, the auger blades may directly collide with the barrel lining, posing a serious threat to equipment safety. It should be noted that: Bending of the auger shaft can be corrected, but torsional deformation cannot be repaired without disassembly and replacement. 4. Non-Disassembly Correction Method for Extruder Auger Shaft For brick factories with limited financial resources or maintenance capability, on-site flame straightening can be used to repair the shaft. The specific procedure is as follows. Step 1: Remove the Auger Blades All auger blades mounted on the shaft must be removed so that the shaft body is completely exposed. Step 2: Determine the Bending Position Manually rotate the auger shaft and use a scriber or dial indicator to determine: The highest bending point The lowest bending point The center of the bending position These locations should be clearly marked. In most cases, bending occurs near the root of the front bearing. Step 3: Bearing Protection To prevent damage to the bearings during heating, protective measures should be taken: Wrap asbestos rope around the shaft at the bottom of the feed box Apply wet clay material outside the asbestos layer This insulation prevents heat from transferring to the bearing and avoids bearing annealing. Step 4: Shaft Support Place the following support tools under the bending position: Steel shims V-shaped support blocks This ensures that the bearings will not be damaged during the correction process. Step 5: Flame Heating and Straightening Use an oxy-acetylene flame to heat the bent section of the shaft evenly. Once the shaft surface reaches a uniform red-hot state, strike the far end of the shaft using an approximately 18-pound hammer to gradually correct the shaft alignment. During the process, continuously check the shaft alignment with a measuring tool to prevent overcorrection. After correction, the acceptable tolerance is: Auger shaft bending ≤ 1 mm which is sufficient for normal extruder operation. 5. Heat Treatment Reinforcement After Correction Flame straightening may reduce the fatigue strength of the heated area. Therefore, local surface hardening treatment is recommended. Procedure Heat the shaft surface using an oxy-acetylene flame Heating temperature: 830–850°C Rapidly cool the heated area with water Utilize the internal heat of the shaft for tempering Tempering Color Changes During tempering, the surface color typically changes as follows: White → Yellow → Blue When the surface turns blue, immediately cool the shaft with water to stabilize the hardness. Final Requirement The final hardness of the shaft surface should be: ≤ HRC 30 This level ensures sufficient wear resistance while maintaining material toughness. 6. Economic Benefits of On-Site Repair For many small and medium-sized brick factories, replacing an auger shaft is costly. For example: Additional costs include transportation, labor, and downtime losses In many cases, the total economic loss may reach several times the cost of the shaft itself. Using the on-site correction method can: Avoid long production shutdowns Reduce maintenance costs Improve equipment utilization 7. Conclusion Practical experience has proven that on-site flame straightening of a bent extruder auger shaft is an economical, practical, and effective maintenance method. The technique has several advantages: No need to dismantle the equipment Short maintenance time Low repair cost Simple operation For small and medium-sized brick factories with limited maintenance facilities, this method has high practical value and strong potential for industry promotion. Through proper equipment maintenance and scientific repair methods, the service life of key extruder components can be significantly extended, ensuring the stable operation of the brick production line.
