Separation solution for challenging materials
Lessine’s rectangular multi-frequency screens are specially designed for the separation and classification of particles across a wide range of sizes, whether dry, wet, sticky, or abrasive materials. With their innovative technology, these screens offer a separation efficiency of up to 99%, allowing the handling of fine and ultra-fine particles (from 25 mm to 20 µm). Ideal for industries that require robust and reliable screening processes.
Operating principle
Rectangular multi-frequency screens operate by generating powerful acceleration, reaching up to 500 G. This acceleration is created by a complex vibration system that transmits intense forces to the screen mesh, ensuring efficient separation even under difficult conditions like mesh clogging or particle agglomeration. The flexibility of use allows the screen to be configured for various applications, including classification, scalping, safety screening, solid-liquid separation, and dewatering.
Applications
The rectangular multi-frequency screen is especially known for classification and scalping in the following sectors :
- Circular economy and recovery
- Minerals and ores
- Fertilizers, chemicals, fine chemicals
- Food and pharmaceuticals
- Metals and precious metals
Advantages
- Extremely high capacity
- Acceleration up to 500 G
- Increases capacity by 20 to 400%
- Suitable for sticky and wet materials
- Screening down to 20 µm
- 99% separation efficiency
- Eliminates mesh clogging and blinding
