A stacker reclaimer is a dedicated heavy-duty machine used for the stacking and reclaiming operations of bulk materials (such as coal, ore, and bulk grain).
Core Structure and Components
Main Structure: Includes the gantry, portal legs, slewing platform, and counterweight. This forms the machine's base.
Core Working Component: A long boom, at one end of which the stacking or reclaiming head device (such as a conveyor or bucket wheel) is installed.
Slewing Mechanism: Drives the boom to rotate horizontally around the center post, covering a fan-shaped or circular area.
Luffing Mechanism: Controls the raising or lowering angle of the boom.
Travel Mechanism: Usually rail-mounted, enabling the entire machine to move along the length of the stockyard.
Tail Carriage: Connects to the external main conveyor and is responsible for the input or output of material.
Working Principle
Stacking Operation: External material is conveyed via the tail carriage to the boom conveyor and is discharged from the boom head onto the stockpile. By combining boom slewing, luffing, and machine travel, a regular stockpile is formed.
Reclaiming Operation: The bucket wheel at the boom head is activated to rotate and dig into the stockpile. The reclaimed material falls through chutes within the bucket wheel onto the boom conveyor, then passes through a center hopper and the tail carriage to the external system. Continuous slewing and feed of the boom achieve reclaiming.
Main Characteristics
High Efficiency and Continuity: Enables continuous material stacking and reclaiming via the conveyor (stacking) and bucket wheel (reclaiming), resulting in highly efficient operation.
Large Handling Capacity: Hourly handling capacity can reach hundreds to thousands of tons, meeting the high-speed material turnover demands of large ports, power plants, etc.
Blending Function: The layered, full-face reclaiming method can mix materials from different batches, serving a pre-homogenization purpose and stabilizing subsequent production quality.
High Degree of Automation: Modern models can integrate automatic positioning and remote control to achieve automated operation.
Main Application Scenarios
Widely used in industrial fields requiring large-scale, continuous handling of bulk materials:
Ports and Terminals: Stacking and ship loading of coal, ore.
Thermal Power Plants: Coal stacking in storage yards and coal supply to boilers.
Steel Plants: Blending and feeding of raw material yards (ore, coal, sinter, etc.).
Cement Industry: Pre-homogenization yards for raw materials like limestone and clay.
Large Chemical Plants and Bulk Logistics Centers.
