Airflow-type lithium feldspar smashing device

The invention discloses an airflow-type lithium feldspar smashing device comprising a smashing main body, a feeding device, a scrap iron outlet and a discharging device; a smashing chamber is mounted in the smashing main body, and the center of the smashing chamber is provided with an airflow cutting bin; the feeding device is mounted at the right of the smashing main body, and the bottom of the feeding device is provided with a motor; the left edge of a screening chamber is provided with a screen, and an electromagnetic device is mounted in the middle of the screening chamber; a left outlet of the screening chamber is connected with a collecting chamber, and the lower end of the screening chamber is connected with a backflow pipeline; and the scrap iron outlet is formed in a corner at the lower end of the backflow pipeline, and the left side of the scrape iron outlet is provided with the discharging device. The airflow-type lithium feldspar smashing device is used for cutting and smashing a raw material of lithium feldspar by virtue of a high-pressure airflow, so that the defect that iron impurities are mixed in a machine is avoided; in addition, the device is also provided with the electromagnetic device for screening metal impurities in the raw material, so that the purity of the smashed material is increased.
