Different particle sizes of the powder are blocked by different baffles 14 and fall into different feeding hoppers 15, completing the grading operation. The air is discharged after being filtered by the filter bag at the bottom of the air outlet pipe 13. Through the above structure, the crushing component crushes the raw material entering the machine body 1, forming a calcium hydroxide air classification device.

The first elastic plate 51 seals the space between the guide plate 5 and the feeding hopper 11. The raw material enters the bottom of the inner side wall of the rolling plate 23 and the feeding hopper 11 along the guide plate 5. Through the above structure, the arrangement of the raw material entering the bottom of the inner side wall of the rolling plate 23 and the feeding hopper 11 along the guide plate 5 forms a material guiding structure, which realizes the function of guiding the raw material and improves the smoothness of the raw material entering the bottom of the inner side wall of the rolling plate 23 and the feeding hopper 11.
