The rotor breaker 2 cooperates with the first impact plate 3 and the second impact plate 4 to complete the crushing of the materials. During operation, the flexible curtain 5 at the feed port of the crusher body 1 blocks the flying materials and dust, and prevents the gravel dust from escaping to the external polluted environment without affecting the discharge of materials. The dust concentration sensor 8 can monitor the dust concentration in real time and transmit it to the external control platform. When the concentration is high, it automatically adjusts the air volume of the exhaust fan 11 and turns on the No. 1 spray device 6 and the No. 2 spray device 7 to perform atomization and dust reduction treatment on the main dust-producing areas to improve the dust removal efficiency. A protective shell 64 is provided to prevent the atomizing nozzle 63 from being impacted and damaged during the material crushing process. When excessive dust is captured on the filter 10, the external motor is started to drive the gear 18 to rotate, and the filter 10 is lowered into the cleaning chamber 12. The compressed air nozzle 13 is used to achieve rapid dust cleaning. Then the motor reverses to drive the gear 18 and raises the filter 10 into the ventilation duct 9 to continue dust removal to avoid blockage during the dust removal process.
