The crushing motor 5-4 is started to work and drives the crushing cutter 5-2 to rotate so as to crush and refine the calcium oxide entering the crushing box 5-1, the qualified calcium oxide meeting the requirements after refining is sieved by the second screen 5-3, discharged from the discharge port 5-12 and reflows into the screen box 1 again through the feed back port 1-5, and finally uniformly discharged from the fine material outlet 1-4 together with the calcium oxide sieved from the first screen 1-2 and collected in a centralized manner.
Firstly, coarse calcium oxide which is unqualified calcium oxide which is not sieved by the first screen mesh 1-2 in the screen box 1 enters the crushing box 5-1 to be crushed and refined, and can be sieved from the second screen mesh which is fine calcium oxide after refining and then flows back to the screen box 1, so that the coarse calcium oxide is crushed and refined into fine calcium oxide in a closed state and returns to the screen box, and the screen box has the advantages of sealing property, continuity, safety, sanitation and the like.
Secondly, because unqualified calcium oxide which is not sieved by the first screen mesh 1-2 in the screen box 1 cannot stay in the screen box 1, coarse calcium oxide, namely unqualified calcium oxide, is not discharged, the inside and the outside of the vibrating screen cannot be accumulated, and manual treatment is not needed; after the calcium oxide is treated by the vibrating screen, the calcium oxide with different thicknesses is finally and completely qualified and discharged in a unified way;
in addition, as the feeding port 5-11 of the crushing box 5-1 is connected with the coarse material outlet 1-3 of the screen box 1, the discharging port 5-12 of the crushing box 5-1 is connected with the material returning port 1-5 of the screen box 1, the crushing box 5-1 is arranged on the screen box 1 and is externally arranged, the normal screening work in the screen box 1 cannot be influenced by the crushing box 5-1, and meanwhile, the crushing box 5-1 is also convenient to be externally opened for observation, maintenance and the like;
finally, the crushing box 5-1 vibrates along with the sieve box 1 as the crushing box 5-1 is connected with the sieve box 1 and fixed with each other; therefore, under the vibration action of the vibration motor 4: the coarse calcium oxide in the sieve box 1 can be firstly vibrated into the feed inlet 5-11 from a coarse material outlet 1-3, and then is vibrated and enters the crushing box 5-1; meanwhile, the fine calcium oxide in the crushing box 5-1 can vibrate into the feed back port 1-5 from the discharge port 5-12 and then vibrate into the screen box 1, so that the problem that the calcium oxide is blocked respectively when entering or exiting can be avoided.
