Silicon carbide crushing device

The utility model discloses a silicon carbide crushing device. The airflow crusher comprises an airflow crusher main body and a fixed seat, a feeding hopper is arranged at the top in the fixed seat; afixing frame is arranged in the feeding hopper; rolling bearings which are engaged with each other are arranged in the fixing frame. A supporting bearing is connected to the bottom of a rolling bearing in the fixing frame, a stirrer is connected to the inner portion of the fixing frame at the bottom of the rolling bearing, a motor is arranged on one side of the rolling bearing outside the feedinghopper, and a vibration motor is arranged at the bottom of one side of the feeding hopper. The motor arranged on one side of the outer part of the feeding hopper drives the rolling bearings which aremeshed with each other to rotate; and then, the vibration motor on one side of the bottom of the feeding hopper is matched with the feeding hopper to vibrate, so that the silicon carbide at the material leaking hopper can smoo
