旋转供料器作为一种高效的物料输送设备，在工业生产的多个环节发挥着重要作用。其独特的结构设计使其能够在密闭环境下实现物料的连续、均匀输送，既保证了输送效率，又能有效控制物料的流量，广泛应用于粉体、颗粒状物料的处理场景。

　　As an efficient material conveying equipment, the rotary feeder plays an important role in multiple aspects of industrial production. Its unique structural design enables continuous and uniform transportation of materials in a closed environment, ensuring both transportation efficiency and effective control of material flow. It is widely used in the processing of powder and granular materials.

　　从工作原理来看，旋转供料器的核心结构由转子、壳体、端盖等部件组成。转子通常为多叶片式（常见的有 6 叶、8 叶），呈圆柱形，与壳体之间保持微小间隙（一般在 0.1-0.5 毫米）。当设备启动时，转子在电机驱动下绕轴心旋转，物料从上部的进料口进入由转子叶片与壳体形成的密闭腔室（即 “料腔”）。随着转子的转动，装满物料的料腔被带至下部的出料口，此时物料在重力作用下从料腔中排出，完成一次输送循环。在整个过程中，转子与壳体的紧密配合形成了良好的密封效果，能够有效阻止上部进料区与下部出料区的空气流通，这一特性使其特别适用于需要隔绝气压的场合，例如在正压或负压输送系统中，可防止气流反窜导致的物料喷溅或输送中断。

　　From the perspective of working principle, the core structure of the rotary feeder consists of components such as rotor, housing, and end cap. The rotor is usually multi bladed (commonly with 6 or 8 blades), cylindrical in shape, and maintains a small gap (usually 0.1-0.5 millimeters) with the shell. When the device is started, the rotor rotates around the axis under the drive of the motor, and the material enters the closed chamber (i.e. "material chamber") formed by the rotor blades and the shell from the upper feeding port. As the rotor rotates, the material chamber filled with material is carried to the lower discharge port. At this time, the material is discharged from the chamber under the action of gravity, completing a conveying cycle. Throughout the entire process, the tight fit between the rotor and the housing forms a good sealing effect, which can effectively prevent air circulation between the upper feeding area and the lower discharging area. This characteristic makes it particularly suitable for situations where air pressure isolation is required, such as in positive or negative pressure conveying systems, to prevent material splashing or conveying interruption caused by airflow backflow.

　　旋转供料器的运行效率与转子转速、叶片数量密切相关。在一定范围内，转子转速越高，单位时间内输送的物料量越大，但转速过高可能导致物料无法充分填充料腔，反而降低输送效率；叶片数量越多，料腔的容积越小，输送的均匀性越好，适合对流量稳定性要求高的场景（如计量喂料）。此外，物料的物理特性（如粒度、密度、流动性）也会影响工作效果，对于易结块的物料，需在进料口设置破碎装置；对于粘性物料，则需在壳体内壁添加防粘涂层，避免物料附着影响输送。

　　The operating efficiency of the rotary feeder is closely related to the rotor speed and the number of blades. Within a certain range, the higher the rotor speed, the greater the amount of material conveyed per unit time. However, excessive speed may result in insufficient filling of the material chamber, which in turn reduces conveying efficiency; The more blades there are, the smaller the volume of the feeding chamber, and the better the uniformity of conveying, which is suitable for scenarios that require high flow stability (such as metering feeding). In addition, the physical properties of materials, such as particle size, density, and flowability, can also affect work efficiency. For materials that are prone to clumping, a crushing device should be installed at the feed inlet; For viscous materials, an anti sticking coating needs to be added to the inner wall of the shell to prevent material adhesion from affecting transportation.

　　在工业生产中，旋转供料器的用途广泛且针对性强。在粉体加工行业，如化工、制药领域，它常被用于将干燥后的粉体物料从料仓输送至混合机、压片机等设备，其密闭性可防止粉体飞扬造成的环境污染和物料损耗，同时避免外界杂质混入影响产品纯度。在粮食加工与仓储行业，旋转供料器能将谷物、饲料等颗粒状物料从储料罐定量输送至输送管道，配合称重设备可实现精准配料，保证生产过程的连续性。

　　In industrial production, rotary feeders are widely used and highly targeted. In the powder processing industry, such as the chemical and pharmaceutical fields, it is often used to transport dried powder materials from the silo to equipment such as mixers and tablet presses. Its sealing can prevent environmental pollution and material loss caused by powder flying, while also avoiding external impurities from affecting product purity. In the grain processing and storage industry, rotary feeders can quantitatively transport granular materials such as grains and feed from storage tanks to conveying pipelines. Combined with weighing equipment, they can achieve precise batching and ensure the continuity of the production process.

　　在环保与能源领域，旋转供料器的应用同样重要。垃圾焚烧处理中，它可将破碎后的固体废弃物均匀送入焚烧炉，控制进料速度以匹配焚烧效率，避免因进料过多导致炉温骤降或燃烧不充分；在生物质能源生产中，用于输送秸秆颗粒、木屑等原料，其耐磨损设计能适应物料中的少量硬质杂质，延长设备使用寿命。

　　The application of rotary feeders is equally important in the fields of environmental protection and energy. In garbage incineration treatment, it can evenly feed the crushed solid waste into the incinerator, control the feeding speed to match the incineration efficiency, and avoid sudden drops in furnace temperature or insufficient combustion caused by excessive feeding; In biomass energy production, it is used to transport raw materials such as straw particles and sawdust. Its wear-resistant design can adapt to the small amount of hard impurities in the materials and extend the service life of the equipment.

　　在建材行业，如水泥、陶瓷生产中，旋转供料器负责将水泥粉、陶瓷原料等从研磨设备输送至成型机，其稳定的输送能力可保证原料供应均衡，减少因物料波动导致的产品质量偏差。此外，在负压吸送系统中，旋转供料器还能起到 “锁气阀” 的作用，通过转子的旋转不断补充物料，维持系统内的负压环境，确保吸送过程的稳定进行，例如在玻璃厂的石英砂输送中，可有效避免粉尘泄漏污染车间环境。

　　In the building materials industry, such as cement and ceramic production, the rotary feeder is responsible for transporting cement powder, ceramic raw materials, etc. from the grinding equipment to the forming machine. Its stable conveying capacity can ensure a balanced supply of raw materials and reduce product quality deviations caused by material fluctuations. In addition, in the negative pressure suction system, the rotating feeder can also play the role of a "locking valve", continuously replenishing materials through the rotation of the rotor, maintaining the negative pressure environment in the system, and ensuring the stable progress of the suction process. For example, in the quartz sand transportation of a glass factory, it can effectively avoid dust leakage and pollution of the workshop environment.
