Adopting positive and negative pressure air cooling method for cooling (air cooling+water cooling can also be used), reasonable
anti blocking devices are installed inside the fluidized bed for easy cleaning; The prototype of this institution adopts positive
and negative pressure dual cooling dust removal. After crushing the sand, the residual temperature on the automatic line is much
higher than the temperature allowed by manual molding (room temperature ± 10 ℃), especially in situations where the workpiece is
large, the pouring cycle time is short, or in summer.
