1. The
built-in ultrasonic system is in direct contact with the screen to maximize the use of the ultrasonic system. The high frequency generated by the ultrasonic generator is directly reflected on the screen surface, and the exciting force of the material is increased, so that the phenomenon of easy blocking of the network no longer occurs. There are no small particles or materials that are easy to agglomerate. Next. However, the disadvantage of this device is that the generating device is inside the screen. If the screened material is easily conductive, the ultrasonic generating device is easy to be damaged, and it is not suitable to be repaired if it is broken. The entire network frame needs to be disassembled.
2. The
external ultrasonic system is installed on the outside of the machine, and the possibility of damage to the ultrasonic transducer due to conduction is relatively small. However, it is possible that the high-frequency vibration force transmitted by ultrasonic waves will decrease.
No matter what form of ultrasonic generator is selected, it needs to be determined according to the needs of customers and the materials to be screened.
