During the rotation of the receiving and screening frame 4, the fine-grained edible salt inside can be affected by centrifugal force and thrown out from the screening mesh cover 6 to the outside, so that the small-grained edible salt is separated from the salt blocks inside. On this basis, after rotating for a period of time, the large-grained edible salt inside can collide with the frame and the remaining edible salt, so that its volume becomes smaller, so that it can be screened out from the screening mesh cover 6. This method can also process the agglomerated edible salt blocks so that they reach the required particle size and are screened out of the outside. Compared with the vibration screening method, this screening method can screen the edible salt multiple times, which is convenient for users to choose whether to crush and screen the edible salt according to their needs, thereby improving the flexibility and functionality of the equipment.

The screened edible salt collides with the inner wall of the box and falls onto the inclined guide plate 14 below. It slides to the opening 15 due to the influence of the inclination angle of the guide plate, and falls into the lower hopper 3 through the opening 15, and is finally discharged from the blanking collection port 16. After the screening is completed, the feed end 5 is rotated to the lower bottom, and the electric telescopic rod 9 retracts inward, so that the block 8 is no longer restricted. The hinge drives the feed cover 7 to flip open through the downward gravity to discharge the residual edible salt inside.
