Principle Introduction

The motor generates kinetic energy during operation, causing the machine body to vibrate and drive the material across single or multiple screen decks. The material is separated into different particle size fractions or impurities are removed from slurries. During the screening process, the material rolls across the screen surface, allowing it to pass through the mesh more smoothly.

The ultrasonic screen-cleaning system superimposes a high-frequency, low-amplitude ultrasonic vibration onto the screen surface. Ultra-fine powders are subjected to strong ultrasonic acceleration, keeping the material in a suspended state on the screen. This effectively suppresses mesh-blocking factors such as adhesion, friction, flattening, and particle wedging, thereby improving screening efficiency and screen-cleaning performance. It addresses screening challenges associated with strong adhesion, easy agglomeration, high static electricity, high fineness, high density, and low bulk density materials.

Equipment Advantages

• Suitable for separating difficult-to-screen materials in the 10–200 micron range; screening fineness up to 400 mesh
• Can be configured with 1 to 5 layers of screens with different mesh sizes according to material separation requirements
• Circular discharge outlet design with freely adjustable positioning, convenient for production layout
• Modular structure for easy assembly, disassembly, and cleaning
• Simplifies the separation of materials with special properties without altering their characteristics, making it especially suitable for new materials
• Elastic balls or ultrasonic screen-cleaning systems effectively prevent mesh clogging or near-size particle blinding, extending screen service life
• Low and stable operating temperature with no localized overheating, allowing continuous operation
• No special foundation required; compact footprint
