What is a Heavy Duty Apron Feeder?
A Heavy Duty Apron Feeder, also known as a heavy plate feeder or chain plate feeder, is a material handling machine used to convey and regulate the flow of large-sized bulk materials. It is commonly installed beneath hoppers or stockpiles to deliver material consistently to jaw crushers, bulk material belt conveyors, and processing systems.
Featuring steel pans, heavy-duty chains, and reinforced drive components, the feeder is designed to withstand high loads, impact forces, and abrasive materials. It is widely used in mining, quarrying, metallurgy, cement, coal, and other heavy industries where reliable feeding of coarse and dense materials is required.

Working Principle
A Heavy Duty Apron Feeder transfers bulk materials by using heavy-duty steel pans mounted on dual chains. The drive system powers the chains and pans to move at a controlled speed, carrying material from the hopper discharge point to crushers, screens, conveyors, or other downstream equipment. It has a robust structure allows reliable handling of large, heavy, abrasive, and high-temperature materials under continuous operating conditions. The following is key components work together:
Tensioning Device: A spiral screw tensioning mechanism, paired with composite springs, consistently maintains the chain’s pre-tension, ensuring proper engagement between the sprocket and the chain. Simultaneously, it absorbs vibrations caused by the impact of large-sized materials, preventing chain slack and protecting critical components.
Support Rollers / Carrier Rollers: These provide support for the apron plates, bearing the combined weight of the plates and the conveyed material. They reduce operational resistance and prevent excessive deflection of the apron plates—caused by their own weight—from disrupting smooth operation.
Apron Plate Assembly: Features a modular, overlapping-arc structure constructed from low-alloy steel plates, offering high strength and excellent wear resistance. The tightly overlapping design ensures zero material leakage. The traction chain typically utilizes heavy-duty bulldozer-style track chains, characterized by minimal pitch error, smooth motion, and high tensile strength, thereby requiring infrequent lubrication.
