Double-Layer High-Frequency Vibrating Screen

The double-layer high-frequency electromagnetic vibrating screen is an effective screening device that uses an electromagnetic exciter to drive the screen at high frequencies, achieving fine classification of materials. Its double-layer screen design allows for simultaneous screening of two different particle sizes, improving production efficiency. It is widely used in mining, building materials, chemicals, food, and other industries. 

Key characteristics 

1. High-Frequency Electromagnetic Vibration (50-100Hz): 

Uses an electromagnetic exciter with high vibration frequency and small amplitude, suitable for fine screening. The vibration intensity is adjustable to accommodate different material properties.

2. Double-Layer Screen Design: 

Enables simultaneous classification of two different particle sizes, improving screening efficiency. The screen is easy to replace and can be made of stainless steel, polyurethane, etc. 

3. Energy saving: 

Electromagnetic drive with low energy consumption, saving over 30% compared to traditional mechanical vibrating screens. High screening efficiency and large processing capacity make it suitable for continuous production. 

4. Compact Structure and Easy Maintenance 

Fully enclosed design to reduce dust emission and meet environmental requirements. No mechanical transmission parts, resulting in low failure rates and simple maintenance. 

Working Principle 

The electromagnetic exciter is energized with high-frequency alternating current, generating periodic electromagnetic forces that drive the screen to vibrate at high frequencies. Materials enter the upper screen, with coarse particles retained on the upper layer and fine particles passing through to the lower layer, achieving two-stage screening. The screened materials are discharged through the outlet, completing the classification. 

Main applications 

Mining industry; Classification of iron ore, copper ore, gold ore, etc. 

Building materials: Screening of quartz sand, cement, ceramic powder, etc. 

Chemical Engineering: Fine classification of fertilizers, plastic pellets, catalysts, etc. 

Food: Screening and impurity removal of flour, starch, sugar powder, etc. 

Environmental protection: Solid waste treatment, renewable resource recovery
