High Frequency Screen

Product Description

The high-frequency screen is an efficient screening equipment. Its core feature is high-frequency vibration and low amplitude. It uses high-frequency vibration to quickly separate fine particles, clay substances or moisture from the materials. 
It is widely used in fields such as food, building materials, and chemical industry. For example, it is used in mineral screening, coal slime dewatering, and fine powder classification. Compared with ordinary screening equipment, it has higher screening efficiency, stronger ability to handle fine materials, and can also reduce material blockage of the screen mesh, lower energy consumption, and is a key equipment for separating fine particles.

Working principle

The core working principle of the high-frequency screen is the combination of high-frequency low-amplitude vibration and material layer separation: The screen box is driven by a vibration motor or exciter, generating high-frequency and small-amplitude vibration that is transmitted to the screen mesh. After the materials fall off the screen, the high-frequency vibration breaks the adsorption force between the particles, causing them to become loose and separate into layers - coarse particles move along the screen surface to the coarse material outlet, while fine particles pass through the screen to the fine material outlet. At the same time, the low-amplitude vibration prevents coarse particles from bouncing excessively, and the high-frequency vibration prevents fine particles from blocking the holes, achieving efficient separation. It is suitable for processing fine ores, coal slimes, etc.

Product 

1. Unique vibration characteristics: Centered on high frequency and low amplitude, the vibration frequency is much higher than that of ordinary screens. The amplitude is small and concentrated in the screen mesh area, which can precisely act on fine materials and reduce the overall equipment shaking;
2. Strong adaptability for fine particle processing: Designed for micrometer-level, clay-containing, water-containing or easily agglomerated fine materials, it can quickly break the adsorption force between fine particles, avoid material agglomeration, and ensure the separation effect;
3. Good screen mesh anti-blocking performance: The high-frequency vibration continuously shakes the screen mesh, which can promptly remove the fine materials stuck in the sieve holes, significantly reduce the probability of blockage, and decrease the frequency of equipment shutdown for cleaning;
4. Efficient and energy-saving operation: The low amplitude design reduces equipment wear and noise, the high-frequency motor has relatively lower energy consumption, and at the same time, the separation accuracy and operational continuity are high, resulting in better long-term operation costs.
