According to the function, select the type of equipment: portal stacker reclaimer, etc. The reason is that this kind of equipment has complete functions and can meet the needs of most conditions. The basic function of the above-mentioned equipment is to stack materials to or take materials from the stockyard. The stacker reclaimer has stacker function, the reclaimer and stacker only have reclaimer or stacker function, the mixing reclaimer and mixing stacker not only have reclaimer and stacker function, but also have homogenization function, so as to meet the user's requirements for material homogenization.

In the actual selection, the following principles can be followed: it is applicable to the condition that the number of material stacking yards is small and the number of stacker reclaimer equipment is small, such as one or two yards of small bulk cargo port, power plant, cement plant, chemical plant, etc. stacker reclaimer can stack materials from two yards or reclaim materials from two yards respectively. One or two stacker reclaimers can stack and reclaim materials from all adjacent yards. But at this time, the equipment operation rate is high. When there are many stockyards, such as three or more stockyards, stacker reclaimer can also be selected when each equipment is required to have a stacking and reclaiming process. Compared with reclaimer and stacker, the equipment cost of stacker reclaimer is higher. Reclaimer and stacker are suitable for large bulk cargo port project.
