Bucket Wheel Stacker Reclaimer return home
wheel stacker reclaimer
is a kind of machine to transport the bulk solids materials in
the stockpile yard .The stockpile yard is a place to store some bulk solids
materials like coal ,iron ore ,limestone etc. Most of the machine are used
in port , power plant , steel plant , and cement mill and so
are many of the machines are used in the world .
There are many type of the machines ,for example , stacker , bucket wheel reclaimer , combined bucket wheel stacker reclaimer .bridge type reclaimer ,gantry type stacker reclaimer, scrapper reclaimer , blending reclaimer ,blending stacker etc . Most of the custom use the combined Bucket wheel stacker reclaimer .
This essay will introduce the combined bucket wheel stacker reclaimer .
wheel stacker reclaimer include many mechanism and structure ,Bucket
wheel , boom ,boom belt conveyor ,luffing mechanism ,slewing
mechanism , gantry , travel mechanism ,slewing platform , tripper car ,
cable reeling drums , cabin , electric room , water spry system
The capacity of stacking and reclaiming can be designed for a few hundred to ten thousand tons per hours .The largest of the equipment has been made in Austrian.
When you use a stacker reclaimer ,
you can use only one equipment to requite the function in the
stockpile yard .
Combined bucket wheel stacker reclaimer machine can stack the material to form the stock pile or reclaim the stockpiled material and feed onto the main line conveyor.
1.Bucket wheel mechanism
Bucket wheel mechanism locating on the head of
the boom . when the boom is slewing and the bucket wheel is turning
, the buckets excavate the material ,and discharge to the boom belt
conveyor .The bucket wheel is designed cell or cell-less type and fitted with replaceable
buckets . The replaceable buckets are equipped with exchangeable hardwearing cutting
lips. The tips of the bucket are of wear resisting
steel. A hydraulic coupling is provided between the motor and the
2 .Luffing mechanism
Luffing mechanism has often been designed to be droved by motor, reducer ,hoist drum , steel rope system to hoisting the boom up or down .and adjust the boom's luffing angle . Now ,more and more the machine's luffing mechanism has been designed to used the hydraulic cylinders to drive the boom up and down. The upper and lower positions of the bucket wheel boom are limited by control and limit switches usually . The spherical plain bearings of ends of cylinder piston are used normally .
The combined Bucket wheel stacker reclaimer is supported on the travel wheel bogies .For a statically determined way the designers often used three corner points to support the gantry . The travel wheels have double flanges . Some time the motor drive one wheel and some time the motor drive two wheels . The drive device is combined by motor ,reducer ,open gears ,brake ,coupling . Each drive is power by a AC motor normally.
