The pendulum feeder is a type of intermittent feeding equipment widely utilized in the mining, metallurgy, and building materials industries. Its core operating principle involves employing an eccentric mechanism to drive a base plate in a reciprocating pendulum motion, thereby conveying materials uniformly and continuously to the subsequent processing stage.

The most distinctive features of this equipment are its simple structure, reliable operation, and low maintenance costs. Due to the minimal number of major moving parts, the failure rate is extremely low, making it particularly well-suited for long-term operation in harsh environments characterized by high dust levels. The pendulum feeder possesses robust adjustability; by modifying the eccentricity of the eccentric wheel or adjusting the motor frequency, operators can easily alter the amplitude and frequency of the base plate's oscillation, thereby precisely controlling the feeding rate. Furthermore, the device demonstrates strong adaptability to various materials, capable of handling both lumpy ores and granular raw materials without being prone to clogging during the feeding process. Certain heavy-duty models also feature excellent impact resistance, enabling them to withstand the substantial pressure exerted by materials stored within the overhead hopper.

In terms of application, the pendulum feeder frequently serves as a primary feeding device for coarse crushers (such as jaw crushers) and is widely employed for conveying raw ore in metal beneficiation plants. In cement production lines, it is responsible for uniformly feeding raw materials—such as limestone and clay—from storage silos into crushers or grinding mills. In the coal industry, it is commonly used to supply material to screening equipment or coal washing systems. By virtue of its stable feeding performance and exceptional durability, the pendulum feeder has become an indispensable link in numerous bulk material handling production lines, effectively ensuring the continuity and efficiency of subsequent crushing and grinding operations.
