Reciprocating Stoker Vibrating Feeder

The K-type reciprocating stoker vibrating feeder is used to feed coal or other loose granular materials with low abrasion and low viscosity, and continuously and uniformly discharge the materials in the storage bin or pit to the transportation equipment or other screening equipment.
  • Description

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.


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.
