Stacker Reclaimer

StackerReclaimers can be found in cement, power, steel industries where bulk movementstorage is needed. Stackers receive material from other stockyard equipment via a conveyor network and deposit it in a bunker or pile. Reclaimers remove the same material and deliver it to other stockyard equipment via a conveyor network.
It is very important to have information such as movement of stackerreclaimer to control room while in operation. For example, if reclaimer is to be started, the reclaimer yard conveyor has to be started first and the same signal is to be given to the reclaimer. In the same way, the stacker yard conveyor has to be started after starting the stacker machine only. So stacker running signal is sent to the Central Control Room (CCR), which in turn, sends signal to stacker yard conveyor. If there is a delay in these signals then tippler chute will get clogged. The main requirement of the signal interlocking is to prevent the clogging of both machine.The wireless approach not only avoids CCRD cable but also avoids CCRD drum and motor to run it. Furthermore, the signals can be easily expanded in future. If PLC's are not available, then hardwire IO's can also be transferred wirelessly.
