Ultrasonic Sieving Machine

What is Ultrasonic Sieving Machine?

Ultra-fine powder material screening, ultrasonic system to solve the screen blockage, can automatically clear the screen

Ultrasonic Sieving Machine is an ultrasonic screening system installed on the basis of ordinary Sieving Machine. The purpose is to prevent mesh clogging and solve difficult screening of powdery materials such as strong adsorption, easy agglomeration, high static electricity, high fineness, and light specific gravity. For problems, the material penetration rate can be increased by 50%-400%, the output can be increased by 0.5-10 times, and the screening accuracy can reach 95%. Under the same sieve surface, the output of the ultrasonic sieving machine is 10 times higher than that of the ordinary sieving machine, and the sieving range can reach 20µm.

Ultrasonic Sieving Machine Function

Solve the blocking of the screen: the screen frame runs three-dimensionally under the action of the vibration motor and superimposes the high-frequency and low-amplitude ultrasonic vibration, so that the material is suspended on the screen surface at a low altitude, thereby effectively solving the problem of the blocking of the material.

Secondary crushing: some materials will cause problems for the troupe when they are damp or friction generated static electricity. Under the action of ultrasonic waves, the aggregated materials can be secondary crushed, thereby increasing the output.

Light specific gravity screening: When ordinary vibrating screen screens light specific gravity materials, it is prone to material spillage and the screening accuracy cannot be achieved. Ultrasonic sieving machine can effectively improve screening accuracy and reduce dust spillage under the action of ultrasonic waves.
