The chain conveyor is set at the front end of the rotary kiln feeding device. The grab grabs the material in the slag pit to the hopper of the chain conveyor, which is uniformly transported to the feeding device of the rotary kiln through the chain conveyor.

The slag is set at the slag discharge outlet of the rotary kiln, and transports the burnt high-temperature ash and slag from the bottom of the rotary kiln to the ash hopper. The slag tapping machine adopts a water seal structure to prevent a large amount of air from leaking into the kiIn during the slag unloading process, which will affect its combustion conditions.
