Specific embodiments

[0021] In this embodiment, three roadbeds are arranged on the ground, each of which is provided with a belt conveyor n.9, n.10 and n.11, and each is equipped with a cantilever stacker and reclaimer. During the material reclaiming operation, the materials can be stacked on the stacking conveyor line of the mixing yard through the output belt conveyor, thereby realizing the first step mixing function of different materials on the three material lines.

[0022] An elevated platform 4 is built between the roadbeds of n.9 and n.10, and between n.10 and n.11, on which an input belt conveyor and its enclosed corridor are arranged, and a mobile unloading trolley is provided.

[0023] There is a material taking channel under each elevated platform 4, in which a ground belt conveyor is arranged, and three BEW rotary impeller feeders are arranged on each of them.

[0024] The platform receives incoming materials and performs unloading operations. The materials are piled up in the primary material yard, and different materials are stored in separate piles. There are no retaining walls or partitions below the elevated platform 4, and the roof of the steel structure enclosed plant is considered to be supported above. The powder ore pile below the elevated platform 4 is ladder-shaped with a pile height of ~15m. The reclaiming operation is performed in the channel below the platform. The three BEW rotary impeller feeders on each reclaiming line can reclaim materials from three material piles at the same time, realizing the first step of the mixed output function of the three materials. Then, the reclaiming line can be further superimposed on the pile line of the mixing yard to increase the variety of mixed materials.

[0025] The closed workshop of the material yard can be divided into N spans according to the size of the material yard. In this embodiment, the material yard has 4 spans from north to south, with spans of 83m, 78m, 78m, and 100m respectively. Except for the last two spans with common columns, there is a 6m wide unloading corridor between the other two adjacent spans. Several material piles are arranged in the workshop to meet the storage needs of different types of minerals.

[0026] The mixing yard is a conventional yard, and various modes can be used. The mixing piler 6 receives the incoming materials from the primary yard and makes a pile, and performs the second step of mixing on the incoming materials from the primary yard. After that, the mixing reclaimer 7 adopts the flat-laying intercepting operation mode to implement the third step of mixing.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
