[0002] Sintering production is a process in the iron and steel metallurgical field, which provides high-quality sintered lump materials for the subsequent blast furnace production process. The quality of the sintered lump materials will directly affect the blast furnace production process.

[0003] During the sintering production process, after the mixed materials arranged on the trolley are ignited, under the action of wind force, they start to burn from the upper layer downwards.

[0080] In some embodiments of the present disclosure, lump ore coolers of different scales can be divided. For example, the middle diameter of the lump ore cooler can be selected based on the floor area, and then the specifications of each functional unit can be selected based on the middle diameter.

[0081] In the example, the division can be carried out according to Table 1 below:

[0082] Table 1 Corresponding relationship between floor area and middle diameter

[0083]

[0084]

[0085] In some embodiments of the present disclosure, after determining the middle diameter, functional units with appropriate specifications can be selected based on the middle diameter. Each functional unit will be described separately as follows:

[0086] In some embodiments of the present disclosure, the driving unit can drive the rotary material cooling unit to perform a rotary motion along a preset path in the platform-type lump ore cooler, so that the sintered lump materials are affected by the cold air conveyed by the air supply unit during the motion, and the sintered lump materials are cooled.
