When the machine is stopped, the controller controls the electromagnetic valve 40 to be closed, water feeding is stopped, then the blanking device is stopped, blanking is stopped, and then the primary slaker water distribution bin 1, the secondary slaker bin 2, the tertiary slaked lime stabilizing bin 3 and the dust removal box 4 are closed in sequence in the reverse order of starting.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
