Ultrasonic crushing device for strengthening complex ore separation

The invention belongs to the field of mineral processing and powder preparation, and discloses an ultrasonic crushing device for strengthening complex ore separation and a use method. The device mainly comprises a feeding bin, a water replenishing bin, an ore crushing barrel, an ultrasonic generating device, a solid-liquid separator, a circulating water device and a power supply, an ultrasonic transducer of the ultrasonic generating device is fixed on the supporting device and can move up and down to press a material to be crushed; a sieve plate is arranged between the cylindrical ore crushing barrel and the inverted-truncated-cone-shaped ore crushing barrel, a spring is arranged on the lower portion of the sieve plate, and the spring vibrates to facilitate falling of crushed ore particles; water of the water circulation system can cool the ultrasonic transducer on one hand and can improve the crushing efficiency on the other hand. The device provided by the invention can reduce crystal penetration crushing a
