Using the above structure, the ultrafine grinding motor 11 is started under the control of the controller 5, so that the pulley 13 can drive the agitator 14 to rotate on the inner wall of the mixing bin 6.

Utilizing the above structure, through the shape characteristics of the feed bin 706, the feed bin 706 can quickly flow the calcium hydroxide on the inner wall of the feed bin 706 downward without excessive accumulation.

[0024] In a preferred embodiment, the servo motor 701 is electrically connected to the controller 5, the cross-section of the feed bin 706 is trapezoidal, the shape of the discharge hole 705 is circular, and the discharge holes 705 are evenly distributed at the bottom of the crushing bin 704, and the bottom of the crushing bin 704 is located on the inner wall of the mixing bin 6. Using the above structure, through the setting of the discharge hole 705 and the position characteristics of the discharge hole 705, it can be seen that the inner wall of the crushing bin 704 makes the limestone and water react more thoroughly to produce purer calcium hydroxide.

[0025] In a preferred embodiment, the first-stage digester assembly 8 includes a mixing drum 801, a drum cover 802 is installed on the outer wall of the mixing drum 801, a stirring motor 803 is installed on the outer wall of the drum cover 802, the power output shaft of the stirring motor 803 is fixedly equipped with a rotating shaft 804, the outer wall of the rotating shaft 804 is respectively equipped with a mounting frame 805 and a stirring blade 807, and the outer wall of the mounting frame 805 is fixedly equipped with a scraper 806.
