[0027] Working principle: The first motor 304, the second motor 508 and the third motor 203 are started at the same time, the output shafts of the first motor 304 and the second motor 508 rotate, respectively driving the first screw conveyor paddle 303 and the second screw conveyor paddle 507 to rotate, the output shaft of the third motor 203 rotates, and then drives the connecting block 202 and the crushing cylinder 201 to rotate together, and the crushing cylinder 201 rotates and then drives the first screen 401 and the second screen 402 to rotate, and the second screen 402 rotates and then drives the material plate 511 to rotate; then, feed the material from the feed pipe 102 The chemical raw materials are put into the crushing drum 201 and the protrusions on the casing 101, and the crushed chemical raw materials fall onto the first screen 401. Due to the rotation of the first screen 401 and the second screen 402, the spiral guide rod 404 is driven to rotate, and the crushed chemical raw materials gradually move downward following the guidance of the spiral guide rod 404. While moving, the first screen 401 and the second screen 402 can separate the chemical raw materials with smaller particles, and the chemical raw materials with larger particles fall onto the temporary storage plate 103.

[0028] Since the aperture of the first sieve 401 is smaller than that of the second sieve 402, the particle size of the chemical raw material screened by the first sieve 401 is smaller than that of the second sieve 402. Therefore, the chemical raw materials that meet the particle size and are relatively small fall from the first sieve 401 to the corresponding third sieve 403. Since the aperture of the third sieve 403 is smaller than that of the first sieve 401 and the third sieve 403 is inclined toward the center, the chemical raw materials that meet the particle size fall from the third sieve 403 to the collecting chamber 601 and are collected, while the relatively small chemical raw materials fall from the first return port 3011 to the first screw conveyor paddle 303, and are transported to the connecting block 202 by the first screw conveyor paddle 303, and then are collected from the opening of the connecting block 202. The chemical raw materials flow into the casing 101 and are crushed again by the crushing drum 201, while the relatively large chemical raw materials fall from the second screen 402 onto the corresponding third screen 403, and finally fall into the first screw conveyor paddle 303 from the second return material port 3012, and are transported to the connecting block 202 by the first screw conveyor paddle 303, and then flow into the casing 101 from the opening of the connecting block 202 and are crushed again by the crushing drum 201. Since the first return material port 3011 is arranged above the second return material port 3012, the materials from the first return material port 3011 will return to the casing 101 faster and be crushed by the crushing drum 201, thereby shortening the return distance of the chemical raw materials with smaller particle size, reducing the transportation time of the particles with smaller particle size, and improving the discharge speed.

[0029] Due to the rotation of the material shifting plate 511, the chemical raw materials with larger particle sizes above the temporary storage plate 103 are shifted and then rotated, and finally flow into the second return pipe 505. The second screw conveying paddle 507 rotates, so that the chemical raw materials with larger particle sizes are transported from bottom to top, and finally fall back into the casing 101 and are crushed again by the crushing drum 201.
