The function is as follows: the reactor is an aging reactor and keeps the same parameters as the iron removal reactor, but the stirring speed of the iron removal reactor is far lower than that of the iron removal reactor. The distance between the paddle and the bottom is to ensure that solid particles cannot be deposited at the bottom of the reaction tank in the aging process, the deposition phenomenon can occur when the paddle is too high, and the motor load can be increased when the paddle is too low. The diameter of the paddle basically has the same effect as the off-bottom effect, solid particles are easily deposited due to too short a paddle, and the load of the motor is increased due to too long a paddle. The distance between the two blades mainly keeps certain intensity of stirring, the stirring intensity at the upper part is low due to the excessively short distance, and an upper stirring laminar flow and a lower stirring laminar flow can be formed due to the excessively long distance, so that the aging reaction is not facilitated.
Furthermore, the automatic stone powder feeder is automatically controlled by an electromagnetic valve, and the feeding speed and the feeding amount are controlled through input to carry out automatic feeding.
