Abstract
An impact crusher comprises a machine shell, a feeding device, a crushing cavity, a rotor and a discharging channel. The impact crusher is characterized in that a discharging port of the feeding device is provided with a dust blocking device which is used to block dusts from the inside of the machine shell. An airflow forming device is arranged below the crushing cavity, an air induced draft device is arranged above the crushing cavity, the airflow forming device forms rising airflow inside the crushing cavity, the airflow and dusts inside the crushing cavity come across to form dust flow, the air induced draft device forms a negative pressure area above the crushing cavity, so that a large amount of dust flow is guided to the negative pressure area, and the dusts are blocked by the dust blocking device and can not be discharged from the discharging port and can only be discharged from the machine shell through the air induced draft device. The air induced draft amount of the air induced draft device can be adjusted, and the powder content of sandrocks inside the crushing cavity is controlled by adjusting the air induced draft amount. Due to the fact that the amount of inlet air and the amount of induced draft air inside the crushing cavity are adjusted, the effect of dust removing is achieved, the powder content of the sandrocks is controlled, and the adjustment of the fineness modulus of the sandrocks can be achieved.
