The ultrasonic screening system is composed of ultrasonic resonance power supply, oscillator and resonance ring. The high-frequency electric oscillation generated by the ultrasonic resonance power supply is converted into high-frequency three-dimensional oscillation waves by the oscillator. These oscillation waves are transmitted to the resonance ring to make the resonance ring generate resonance, and then the vibration is evenly transmitted to the screen surface by the resonance ring. The materials on the screen are vibrated by low-frequency three-dimensional vibration and superimposed with ultrasonic vibration, which can not only prevent the mesh from blocking, but also improve the screening yield and quality.
Structural principle of ultrasonic vibrating screen:
The ultrasonic vibration wave (mechanical wave) attached to the screen of RA series ultrasonic vibrating screen makes the ultra-fine powder accept huge ultrasonic acceleration, so as to inhibit the screen blocking factors such as adhesion, friction, leveling and wedging, and improve the screening and cleaning benefits.
API refers to the API used in the production of various preparations. It is the effective ingredient in the preparations. Various powders, crystals, extracts, etc. prepared by chemical synthesis, plant extraction or biotechnology for medicinal use, but which cannot be taken directly by patients, need further fine processing.
The screening of API powder is mainly for impurity removal, classification and ultra-fine classification.
