The conical barrel is made of high-quality nitride steel 38crmoala as the substrate, which is refined through multiple processes such as tempering, qualitative analysis, nitriding, precision grinding, and polishing to ensure the strength and wear resistance of the product, meeting industry standards. The conical barrel is usually operated in a closed manner during material processing to reduce material volatilization and environmental pollution. Meanwhile, its internal structure and design can maximize the utilization of heat energy and reduce energy consumption. The price of the conical barrel is reasonable and the maintenance cost is also relatively low. Its high efficiency and versatility make it cost-effective in industrial production, and it is an important support for the efficient operation of production lines and the improvement of product quality.

Product advantage:
The design of the conical barrel can effectively improve the conveying efficiency of materials on the conveyor. Its conical structure can better adapt to materials of different sizes, reduce jamming, and generate a certain driving force during the conveying process, making the materials move forward faster and improving overall conveying efficiency. Compared to traditional cylindrical drums, conical drums roll more smoothly, reducing unnecessary friction and resistance, and helping to lower the energy consumption of conveyors. At the same time, reducing wear and tear also extends the service life of the drum and reduces maintenance costs. The special shape of the conical barrel can play a certain dispersing role in the material conveying process, making the material more evenly distributed on the conveyor line, reducing the possibility of blockage, and improving the stability and reliability of the conveyor line. The design of the conical barrel reduces the generation of vibration and noise and reduces the impact on the surrounding environment and equipment. At the same time, it can better adapt to abnormal situations on the conveyor line, such as material accumulation, conveyor belt deviation, etc., ensuring the stable operation and production safety of the conveyor line.
