Specifically, when first gate valve 211 is opened, and under the closed state of second gate valve 212, the sand material that passes through in ejection of compact distribution bin 200 all can enter into first row of workbin body 213 this moment, to whole machine-made sand production unit this moment, can realize the effect of two-stage differentiation to the sand material, and one kind of sand material gets into first row of workbin body 213, and another kind gets into and connects hopper 300. The two-stage distinguishing condition is suitable for places with low sand distinguishing requirements.
When the first gate valve 211 is closed and the second gate valve 212 is opened, the sand in the distribution chamber 201 of the screen plate 102 located at the highest position in the corresponding screen storage 100 in the discharging distribution bin 200 enters the first discharging box body 213, and the sand in the distribution chamber 201 of the screen plate 102 located at the middle position and the lowest position in the discharging distribution bin 200 enters the second discharging box body 215. In this case, for the machine-made sand production unit lower than the whole, three-level distinguishing effect can be achieved for sand materials, i.e., one kind of sand enters the first discharge box body 213, one kind of sand enters the second discharge box body 215, and the other kind of sand enters the receiving hopper 300. The three-level distinguishing condition is suitable for places with relatively high sand distinguishing requirements.

In yet another alternative embodiment, the second barrel 802 is fed through a second hopper lift 913 to deposit powder into the dry sand compartment 915; the second charging barrel 802 is connected with a hopper of a second bucket elevator 913, and a blanking chute of the second bucket elevator 913 is connected with a dry sand separation bin 915; the dry sand separation bin 915 is connected with a second powder material metering scale 903. The dry sand separation bin 915 here comprises two separate bin bodies, one of which is forced to receive the sand powder in the second barrel 802. The hopper of the second hopper elevator 913 is connected with a third charging barrel 916; the third barrel 916 is connected to a discharge chute of the first hopper lift 600. The sand powder in the third barrel 916 enters the other of the dry sand separation bins 915.
It should be noted that the sand powder in the third barrel 916 in this embodiment does not need to be screened by the vibrating screen 700. Namely, for the three-dimensional integrated processing production line of the common gypsum, the special gypsum and the machine-made sand, the sand powder can be classified for gypsum processing after being screened, and can also be directly processed for gypsum without being screened, so that the three-dimensional integrated processing production line meets the use requirements for environments with different use requirements. That is to say, the embodiment can carry out the processing of ordinary gypsum and special gypsum simultaneously, also can be only ordinary gypsum of production, to this, specific application method can select corresponding production mode according to the actual use demand.
