After the system is started, it operates according to the set steps. First, the batching valves at the bottom of the first batching silo 2-2 and second batching silo 2-5 are opened, and the aggregate falls onto the corresponding weighing conveyor belt. After reaching the set weight, the batching valve is closed, and the aggregate falls from the weighing conveyor belt onto batching conveyor belt 11, then is transferred to the first lifting conveyor belt 3, and finally transferred to the mixing and blending box of mixing and blending device 7. Cement metering device 6 and additive device 4 supply the set amount of cement material and additive to the mixing and blending box of mixing and blending device 7. Mixing and blending device 7 is started to mix and blend the material received inside. After mixing and blending, the mixed material is unloaded onto the second lifting conveyor belt 8 through the unloading machine 12 below it, and finally lifted and transferred to storage silo 10 for temporary storage. The above steps continue to maintain sufficient mixed material in storage silo 10 to avoid interruption in the solid waste wet molding process.
[0034] When picking up materials, park the material cart below the platform frame of the storage machine frame 9, start the unloading machine 12, unload the mixed material in the storage bin 10 into the unloading box 13, open the unloading valve 14, and the mixed material falls into the hopper of the material cart.
