The power source and transducer is the core part of the ultrasonic system,it can transfer electrical energy to high-frequency vibrating mechanical energy.Then made the nets’ frequency reached 36000/min,consequently solve static reunited,block up net,etc,on the screening, and,they Can dispose the material systemicly,optimizelyhich with micropowder,strength absorbtion,light proportion .ultrasonic system is the best way which can make the material pass the net quickly,advance the capacity.
