Stacker Conveyor Systems

stacker conveyor system is a type of material handling equipment used to transport, pile (stack), and store bulk materials like coal, sand, gravel, limestone, or grains in an organized manner.

It combines two main functions:

Conveying → moves material from one point to another

Stacking → deposits the material into stockpiles

Components

Belt Conveyor – carries the material

Boom (Stacking Arm) – extends outward to discharge material

Drive Unit – motor + gearbox to run the belt

Pulley & Idlers – support and guide the belt

Tripper / Shuttle Mechanism – controls where material is discharged

Control System – manual or automated operation

Types of Stacker Conveyor Systems

Radial Stacker

Rotates in an arc

Creates large, circular stockpiles

Common in mining & ports

Telescopic Stacker

Boom length can extend/retract

Ideal for space-saving and precise stacking

Travelling Stacker

Moves along rails

Used in large storage yards

Pipe Conveyor Stacker

Enclosed belt (reduces dust and spillage)

Applications

Mining industry (coal, ores)

Cement plants

Power plants

Ports and terminals

Agriculture (grain handling)
