The pushing method of the S-type grate cooler is completely different from that of the fourth-generation grate cooler of the same type. The unique running track of the clinker has a homogenization effect, which enhances the cooling effect and further improves the heat exchange efficiency. The equipment adopts a completely modular design, and there is no movement mechanism connection between the modules. Each standard module consists of a trampoline frame, a low-resistance and no-leakage fixed raft, and a sweeping conveyor (patent number: ZL200820115279.8). The flow automatic regulator (patent number: ZL200820176603.7) and the driving device are composed, and the trampoline is supplied by the wind chamber.
