subject: Know More About Stacker Reclaimer [print this page] A stacker reclaimer is the big machine utilized in the bulk material management. Its purpose is piling bulk material like ores, limestone, and the cereals to the stockpile. The stacker reclaimer may be utilized to recover its material.
A stacker reclaimer is technically rated for the capability in the tph (tones per hour). They usually travel on the rail between the stockpiles in stockyard. A stacker reclaimer may generally move in minimum two directions: straight along rail as well as vertically through lowering and raising its boom. The luffing of the boom minimizes dust through reducing distance, which material like coal requires falling to top of stockpile. The bang is luffed up as height of stockpile raises. A few stackers may turn around the boom. It permits the single stacker for forming two stockpiles, each one on the either side for conveyor.
A stacker reclaimer is utilized to stack with different patterns like chevron stacking as well as cone stacking. Stacking in the single cone has a tendency to cause the size segregation, having coarser material towards base. In the raw cone work stacking, extra cones are adjoined next to initial cone. In the chevron stacking, a stacker reclaimer travels down length of stockpile addition of layer upon the layer for the material.
Stacker as well as stacker reclaimer was initially manually controlled and not controlled by the remote control. Contemporary machines are usually fully automated or semi-automatic, having parameters distantly set. Its control system is used typically like programmable controller, having human-machine edge for display, associated with the central controlling system.
Except stacking, a stacker reclaimer has three fundamental movements:
Luffing:
It is upright movement. The old stackers are used hoist mechanism having metal wire; however newer one is given by the hydraulic cylinders, usually two.
Travelling:
A stacker reclaimer moves on the rail track that can be gauge or broad, permitting it to agitate the stockyard when needed. For that purpose, the traction motors had powered by the DC (Direct Current), are associated with bevel gears for between 12-22 wheels. For the manual control, all controls are within controller's cabin over boom or boom conveyor. Contemporary stacker reclaimer may be remotely controlled.
Slewing:
It is the rotation for stacker around the central axis for aligning or placing the stockpile wherever required. It works mainly by the slew pinion, which rotates around the slew base. That kind of geared assembly is named the sun & the planet gear. These axles can be multiple as well as are driven through the axle motors having DC-powered that transmit torque through helical or bevel gears.
Conveyor belts are utilized in the stackers can be done of metal or fabric wire, relying upon material that should be handled. They are determined by the pulleys that consecutively driven by the DC motors. These motors as well as gear are joined by the fluid coupling.
Most of the stackers are powered electrically by the way of trailing a cable. Nearby are fundamentally two kinds of cable sprawling: the PCRD (Power Cord Rotating Drum) as well as CCRD (Control Cable Rotating Drum).
