A reciprocating stoker vibrating feeder, also known simply as a reciprocating feeder or stoker feeder, is a type of vibrating feeder commonly used in industrial settings, particularly in power plants and coal-fired boilers. It's designed to deliver coal or other bulk materials from a storage hopper to a pulverizer or other processing equipment in a controlled and consistent manner. 

Reciprocating Stoker Vibrating Feeder Features

Stoker Mechanism: The reciprocating stoker feeder features a mechanism that moves a plate or grate back and forth in a reciprocating motion. This motion helps to distribute and convey the bulk material along the feeder.

Robust Construction: These feeders are typically built with heavy-duty materials such as steel to withstand the abrasive nature of coal and the harsh operating conditions in power plants.

Adjustability: Reciprocating stoker feeders often feature adjustable settings for stroke length, speed, and frequency to control the flow rate and ensure consistent feeding of the material.

Continuous Operation: They are designed for continuous operation, providing a reliable and uninterrupted supply of material to the processing equipment.

Low Maintenance: With relatively few moving parts, reciprocating stoker feeders require minimal maintenance and are known for their reliability and durability.

Reciprocating Stoker Vibrating Feeder Working Principle

Material Loading: Coal or other bulk material is loaded into a storage hopper located above the reciprocating stoker feeder.

Reciprocating Motion: The stoker mechanism moves a plate or grate back and forth in a reciprocating motion. As the plate moves backward, it pulls the material from the storage hopper onto the feeder.

Material Conveyance: The reciprocating motion of the plate distributes the material evenly along the length of the feeder. The material is conveyed forward as the plate moves forward, ultimately discharging onto a conveyor belt, pulverizer, or other processing equipment.

Adjustment: The stroke length, speed, and frequency of the reciprocating motion can be adjusted to control the flow rate and ensure the proper feeding of the material.

Continuous Operation: The reciprocating stoker feeder operates continuously, providing a steady supply of material to the downstream processing equipment as needed.

Applications

Power Plants: Reciprocating stoker feeders are commonly used in coal-fired power plants to feed coal from storage hoppers to pulverizers, boilers, or combustion chambers for combustion.

Industrial Boilers: They are also utilized in industrial boilers and furnaces for feeding coal or biomass fuels into the combustion chamber for heating or energy generation.

Mining and Minerals: In mining and mineral processing plants, reciprocating stoker feeders can be used to feed ore, minerals, or aggregates to crushers, screens, or conveyors for further processing.

Steel Mills: They find applications in steel mills for feeding coke or other raw materials into blast furnaces or coke ovens for steel production.

Chemical Plants: Reciprocating stoker feeders may be used in chemical plants for feeding bulk materials such as granules, pellets, or powders into reactors, mixers, or other processing equipment.
