Preferably, the first compacting roller 24 drives the compacting belt 21 closer to or away from the conveyor belt 1 in advance, so that a suitable compacting gap 22 is formed between the conveyor belt 1 and the compacting belt 21. Optionally, the actual effect of compacting the powder into a ceramic green body can be obtained by compacting the powder into the ceramic green body according to the compacting gap 22. The compacting belt 21 can be driven closer to or away from the conveyor belt 1 by the first compacting roller 24 to adjust the compacting gap 22 and optimize the effect of compacting the powder into the ceramic green body by the compacting gap 22.
