Double Pendulum Flap


Double Pendulum Flaps are also called the double dump/discharge valves. Double dump valves are designed for controlled discharging of large particle size or high-temperature materials from silos, bins, or hoppers in heavy-duty applications. They are often used to discharge material from hoppers, dust collectors, and baghouses and usually, an electric motor powers their operation. They are commonly used in the iron ore pelletizing plant for the continuous dosing, blocking, and discharging of bulk materials. Its robust construction and thoughtful design elements like heat resistance, dustproofing, and easy maintenance aspects underline its critical role in the pelletizing process. Our products are commonly adopted in the indurating department in the iron ore pelletizing plant.

The flaps are made from heat and wear-resistant steel plates, ensuring durability and longevity under the harsh conditions of pellet processing.


These flaps are designed for easy replacement when they become worn, emphasizing the equipment's maintainability.


The flap shafts operate in roller bearings, which are carefully sealed and mounted outside the casing for enhanced protection and reliability.


To ensure a tight seal against the casing and prevent material leakage, adjustable and repackable stuffing boxes are used
