Criba Vibratoria Ultrasónica
Ultrasonic vibrating screens are also known as ultrasonic rotary vibrating screens. This equipment builds upon traditional vibrating screens (such as rotary vibrating screens) by incorporating a high-frequency ultrasonic vibration system to enhance screening efficiency and precision. It is an advanced screening solution designed to address the challenges of processing ultra-fine powders, highly viscous materials, materials prone to agglomeration, and electrically charged materials. Its core value lies in “anti-clogging” and “high precision,” making it a critical piece of equipment in industries such as fine chemicals, pharmaceuticals, food, and new materials (e.g., lithium batteries).
What is an Ultrasonic Vibrating Screen
An ultrasonic vibrating screen, also known as an ultrasonic rotary vibrating screen, is a high-precision screening device that combines ultrasonic technology with the functionality of a traditional vibrating screen. Its core operating principle is “dual-power drive”: on one hand, a vibration motor provides basic mechanical vibration, ensuring that the material is evenly distributed across the screen surface; on the other hand, an ultrasonic system (consisting of a generator and transducers) converts electrical energy into high-frequency mechanical vibrations (typically 20–40 kHz) and superimposes them onto the screen mesh. This high-frequency, low-amplitude vibration effectively breaks down the adhesive forces and electrostatic attraction between materials, causing fine particles to “suspend,” thereby completely resolving the problem of screen clogging during the screening of fine powders and significantly improving screening efficiency and precision.
The JR-C Series Ultrasonic Vibrating Screen is a new type of “high-precision, high-stability” ultrasonic screen developed by Jiarui Machinery based on years of experience in fine classification and through technical cooperation with Germany. This ultrasonic vibrating screen converts 220V, 50Hz or 110V, 60Hz electrical power into 38kHz high-frequency electrical energy, which is then fed into the ultrasonic transducer. This enables efficient screening and screen cleaning, making the screening of ultra-fine powders effortless. Building upon traditional vibrating screens, this system introduces low-amplitude, high-frequency ultrasonic vibrations (mechanical waves) to the screen mesh, thereby enhancing the screening performance of ultra-fine particles. Major application areas include: the chemical industry (e.g., powder coatings, resins, battery materials), the food industry (e.g., milk powder, powdered sugar, starch), the pharmaceutical industry (e.g., Chinese and Western medicinal powders, active pharmaceutical ingredients requiring GMP compliance), as well as the metallurgy and new materials industries (e.g., metal powders, ceramic powders, quartz sand, etc.). Additionally, this equipment plays a significant role in the environmental protection and new energy sectors (e.g., screening of lithium battery materials).
