With the brick and tile industry's increasing demands for product quality, output, and equipment reliability, structural optimization and technological upgrading of vacuum extruders have become particularly important.By researching and analyzing various vacuum extruder equipment developed domestically and internationally, and combining the advanced technical experience of different manufacturing enterprises, a systematic optimization design of key structures is carried out while ensuring equipment performance. By selecting technologically mature and economically reasonable supporting components, equipment functionality is enhanced while effectively reducing manufacturing costs, thereby achieving a comprehensive improvement in both equipment performance and economy. I. Optimization Design of Key Components 1.1 Auger Shaft (Main Shaft) Structure Optimization The auger shaft is the core transmission component of the vacuum extruder. Its main function is to transmit power and push the clay mixture forward, while simultaneously bearing significant torque and axial pressure. Therefore, the structural design of the auger shaft directly affects the overall stability and reliability of the machine.In the original vacuum extruder structure, the diameter of the auger shaft at the bearing positions was Φ170 mm, and it utilized three bearings for support (including one thrust bearing). However, during actual operation, this structure presented the following problems:• Relatively small center distance between the front and rear bearings• Relatively long cantilevered section of the auger shaft• Significant deflection of the shaft during operationThis structure tended to cause noticeable shaking of the extruder head during operation (commonly known as the "head shaking" phenomenon). Excessive or prolonged shaking not only affects the operational stability of the equipment but can also lead to component damage and even production shutdowns. According to mechanical theory analysis:Assume the distance from the front bearing center of the auger shaft to the front end of the auger is L₁Assume the center distance between the front and rear bearings is L₂When the following condition is met:L₂ / L₁ ≥ 0.7the auger shaft can maintain good operational stability.In the original equipment structure:L₂ / L₁ = 1040 / 1950 = 0.533This is significantly below the reasonable design range, thus indicating a structural design deficiency. 1.2 Structural Improvement Scheme During the optimization design process, the key transmission structure was adjusted to achieve a more rational auger shaft configuration.Main measures included:• Changing the original radial pneumatic clutch to an axial pneumatic clutch• Reducing the axial installation dimensions of the clutch• Moving the auger shaft bearing housing rearward Through the above optimizations:The center distance between the front and rear bearings increased by approximately 400 mm.Under the new structure:L₂ / L₁ = (1040 + 400) / 1950 = 0.74This ratio now meets the requirements for stable operation, making the auger shaft run more smoothly and reliably.Due to the increased structural rigidity, the auger shaft diameter could also be optimized accordingly:Original maximum shaft diameter: Φ185 mmOptimized bearing section diameter: Φ150 mmMaximum shaft diameter: Φ160 mmAfter structural optimization:• The shaft weight is significantly reduced• The mechanical structure is more rational• Manufacturing difficulty is decreased Simultaneously, the dimensions of bearings and related components were also reduced, making the entire auger shaft system more compact. II. Pneumatic Clutch System Optimization In the original equipment design, a radial pneumatic clutch was used as the power connection device. This structure had the following disadvantages:• Complex structure• Large footprint• High requirements for installation and commissioning• Strict requirements for equipment alignment accuracy The radial pneumatic clutch required precise alignment with the reducer via a coupling and needed additional support structures, making installation and maintenance more complex.In the optimization design, all radial clutches were replaced with axial pneumatic clutches, installed directly on the high-speed shaft of the reducer.This structure offers the following advantages:• More compact structure• Easier to ensure installation accuracy• More convenient commissioning and maintenance• Significantly reduced equipment weight• Lower requirements for the compressed air systemThrough this improvement, not only was the operational reliability of the equipment enhanced, but the overall transmission structure also became simpler. ​ III. Enhancement of Equipment Production Capacity The original dual-stage vacuum extruder suffered from relatively low output in practical use. Technical analysis identified the main reasons as:• Insufficient feeding capacity from the upper stage• Excessive compression ratio in the tapered cavity• Relatively low conveying speed in the upper stage Compression ratio of the original equipment's tapered cavity:λ = 2.6This value was close to the upper limit of the design allowable range.The typical reasonable range is:λ = 2.0 – 2.6An excessively large taper reduces the conveying speed of the clay mixture, decreasing the amount of material entering the vacuum chamber per unit time, thus limiting the overall machine output.In the optimization design, by adjusting the structural dimensions of the inner and outer tapered sleeves, the compression ratio was optimized to:λ = 2.3Furthermore, due to the replacement with the axial clutch, the rotational speed of the upper stage was appropriately increased, significantly enhancing the clay conveying capacity.After optimization:The amount of clay mixture entering the vacuum chamber per unit time increased by approximately 22%.The production capacity of the new dual-stage vacuum extruder improved by about 25% compared to the original model. IV. Structural Lightweighting and Manufacturing Optimization During the overall equipment optimization process, systematic improvements were made to several structural components to enhance manufacturing efficiency and structural rationality. 4.1 Structural Weight Optimization While ensuring equipment strength and performance, structural optimization was carried out on the following key components:• Feeding box• Vacuum chamber• Machine body structureBy optimizing casting structures and machining processes, the overall weight of the equipment was significantly reduced, while processing efficiency was improved. 4.2 Standardization of Component Design In the original equipment design, some auxiliary components such as:• Filters• Motor slide rails• Lighting systems• Vacuum chamber inspection doors• Varied in structure across different equipment models. In the optimization design, by implementing standardized component design, the following goals were achieved:• Utilizing unified structural parts for different equipment models• Making only appropriate dimensional adjustments• Establishing a system of internal enterprise standard parts This measure brought significant production advantages:• Reduction in the variety of parts• Increased batch production capability• Enhanced processing efficiency• Reduced manufacturing complexity V. Effects of Optimization Design Structure• More compact equipment structure• More rational transmission system• Increased standardization of components Performance• More stable operation of the auger shaft• Significantly improved production capacity• Enhanced equipment operational reliability Manufacturing• Optimized equipment weight• Improved processing and manufacturing efficiency• More rational overall structure In summary, the optimization design has not only elevated the equipment's technical level but also improved production efficiency and equipment reliability, enabling the vacuum extruder to deliver greater value in brick production lines.

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.
