[0022] When granulating and screening compound fertilizer, first prepare the compound fertilizer raw materials, add the raw materials into the feed hopper 3, start the motor 7, and the output shaft of the motor 7 rotates to drive the rear granulating roller 4 to rotate, and then drives the two gears 5 to rotate, which drives the first rotating shaft 401 and the front granulating roller 4 to rotate. The two granulating rollers 4 rotate with each other to crush the raw materials. Due to the circular grooves of the granulating rollers 4 themselves, the raw materials can be squeezed into granules. The formed compound fertilizer granules will fall downward into the unloading plate 14, and the scraper 402 can play a role in cleaning.

After being screened by the second sieve barrel 12, the small particles of compound fertilizer will fall into the fine material collection box 201 through the fine material opening 1201. The large particles of compound fertilizer in the first sieve barrel 10 will accumulate to the right after rolling, and then fall into the coarse material collection frame 15 through the discharge chute 1101. During the rolling screening process of the first sieve barrel 10, some compound fertilizers that cannot be discharged through the fine material opening 1201 will roll to the right, and then be discharged into the miscellaneous material collection box 202 through the discharge opening 1102. The staff can intermittently add raw materials into the discharge hopper to carry out orderly granulation and screening of the compound fertilizer, screen out the compound fertilizer according to size, and automatically complete the collection. The integrated operation improves the work efficiency and reduces the work intensity for the staff. After the work is completed, the motor 7 is turned off, and the compound fertilizers in the fine material collection box 201, the miscellaneous material collection box 202 and the coarse material collection frame 15 can be collected. Some of the compound fertilizers in the miscellaneous material collection box 202 are unqualified in shape and size and can be processed again.
