2. Reclaming

 

The machine reclaims the material from the stockpile in layers by rotating bucket wheel swing across the pile. The material picked up by the bucket is retained and guided by the ring chute as the bucket moves up. When the bucket is about 45 deg above horizontal, the material starts discharging it to the bucket wheel chute, which guides it to the boom conveyor.On reaching the end of the boom conveyor, the material passes through the central chute and portal chute on to the yard conveyor belt, supported on the impact table. The reclamation of the entire stockpile can be carried out either by bench type and modular methods.

In the bench type method the reclaimer starts at one end on the top bench or layer and reclaims that bench for the full length of the pile. On the reaching the end of the pile the machine returns to the other end, the boom is lowered and reclaiming commences on the next lower bench.

The modular method is accomplished by starting at the top of the pile at one end and taking a series of cuts one bench deep end returning to the end of the pile, lowering the boom and taking the same number of cuts on the lower bench. This process is repeated up to the lowest bench thereby completing one reclaim module.
