[0006] Furthermore, the dust collection mechanism includes a dust collector fixedly arranged on the outer side of the crushing box, the air inlet end of the dust collector extends into the upper end of the crushing box, and the dust discharge port of the dust collector is connected to the inside of the aggregate box through a pipeline.

[0007] Furthermore, the double-roller crusher includes two crushing rollers rotatably arranged inside a crushing box, the two crushing rollers are meshed with each other, and also includes two motors 2 fixedly arranged on the outer side of the crushing box, and the driving shafts of the two motors 2 are respectively fixedly connected to the central axes of the two crushing rollers.

[0008] Furthermore, a feed port is provided at the upper end of the crushing box.

[0009] Compared with the prior art, the utility model has the following advantages: a dust suction mechanism is provided between the aggregate box and the crushing box. The dust suction mechanism is designed to timely absorb and process the dust, and the absorbed dust or debris is returned to the aggregate box to participate in the next step of granulation to avoid waste. During the entire granulation process, the dust is effectively collected and discharged, thereby improving the cleanliness of the working environment, protecting the health of the operators, and helping to improve production efficiency and product quality.
