Ultrasonic Vibro Sifter-DAHAN Vibration Machinery

Core Advantage

Ultrasonic vibrating screen VS ordinary vibrating screen - sieving "flour"

Ultrafine Powder Screening

The ultrasonic system solves the problem of ultrafine powder screening with strong adsorption, static electricity, strong viscosity and high density.

Higher Yield

Compared with ordinary vibrating screen, the screening accuracy is increased by 1-70%, and the output can be increased by 0.5-10 times.

Do Not Block The Network

The vibration frequency is 36,000 times/min, high frequency and low amplitude, the material is easier to penetrate the net and can shatter the agglomerated material.

Clean And Hygienic

Fully enclosed stainless steel body design to avoid powder flying.

Compared with ordinary vibrating screen, ultrasonic vibrating screen is more capable:

Model	Ordinary screening machine		Ultrasonic vibrating screen		Test Results
Test material	Mesh	Test material	Mesh
Φ1000	Silicon carbide	500	Can't screen points	500	1500kg/h
	Tungsten carbide powder	600	No fine powder was screened out for 15 minutes	600	30kg/h
	Vitamin C Powder	400	1kg/h	100	120-150kg/h
Φ500	Pollen	400	No fine powder was screened out for 15 minutes	400	Screening out 20% fine powder in 15 minutes can be more fine and more effective grading
Φ500	Nickel powder, Cobalt powder	325	There was a 32.2% sieve residue at 30 min	400	Screening meets the requirements once
Φ450	NdFeB powder	300	The screen meets the requirements for three times	300	There was a 6.9% sieve residue at 30 min

Principle and Structure

The ultrasonic vibrating screen converts 220V, 50Hz or 110V, 60Hz electrical energy into 36KHz mechanical vibration through the transducer, and the vibration is evenly transmitted from the resonance ring to the screen surface, and the vibration of rotation, inclination and jump formed by the excitation force of the upright motor. The three-dimensional motion is combined to carry out the screening work together, which can efficiently screen and prevent the mesh from being blocked.

Feed Inlet-Dust Cover-Screen Frame-Screen-Discharge Port: cooperate to screen materials;

principle

Ultrasonic Power Source-Transducer-grid: the key structure, which generates ultrasonic mechanical energy. It can automatically track the full digital frequency according to the different states of ultrasound, without manual adjustment, and the operation is simple and convenient.

The mesh frame is designed with sticky mesh, which is more firm and solves the problem that the mesh diameter of the ultrasonic rotary vibrating screen is too small and easily damaged.

structure

Motor - Heavy Hammer: power source.

	Flanged ultrasonic vibrating screen: the feeding port adopts flange design to increase the feeding amount, reduce the powder ejection, and facilitate the observation of the screening situation
	Gate type ultrasonic vibrating screen: a gate is designed at the discharge port, which can prolong the material screening time and improve the fineness of material screening by closing the gate.
	Explosion-proof ultrasonic vibrating screen: fully sealed screen box, using explosion-proof motor, suitable for screening of fine materials that are prone to static electricity and flying powder
	Ultrasonic gas protection vibrating screen: install gas protection device to ensure that the material does not contact the air during the screening process and overcome dust pollution
