applications and types of material separators

Material Separator

As awareness of emissions management and recycling increases, material separators play a vital role in modern emissions treatment systems. These machines efficiently separate emissions based on the material’s physical, chemical, or optical properties, thereby increasing recycling rates and reducing environmental impact. Material separators have standard classifications and types, maximizing them with unique functions and application scenarios. 

types of material separators

Mechanical separation utilizes the material's mechanical properties, such as size, shape, and density.

Mechanical separation

Screening:

  • Separation is carried out using screens with different apertures depending on the particle size of the material.

Wind Sorting:

  • Separation of materials of different masses and shapes using aerodynamic forces.

Gravitational sorting:

  • Utilizes the difference in specific gravity of materials to separate them in a fluid or solid medium.

Optical separators utilize sensors and light sources to differentiate materials based on their optical properties.

Optical Separation

Magnetic Separation

  • Magnetic separation utilizes the magnetizing properties of materials to separate them. Magnetic separators use a strong magnetic field to separate magnetic and non-magnetic materials.

Induction Separation

  • Induction separators utilize the electromagnetic induction properties of materials to perform separation. Induction separators utilize eddy currents or electromagnetic fields to separate conductive and non-conductive materials.

Eddy current separators utilize the eddy currents generated by conductive materials in an alternating magnetic field to separate.

Eddy Current Separation

Eddy current separators utilize a rotating magnetic field to eject the conductive material. Different material separator types are available for different discharge streams, including solid waste and e-waste. By choosing the correct material separator, discharge management professionals can dramatically increase recycling rates, reduce environmental footprints, and promote sustainability.

Equipment included in a small-scale plastic waste recycling plant

1: Belt Conveyor


Convey plastic waste to plastic crusher in bulk and efficiently.

 

2. Plastic Shredder

Used to deal with large pieces of raw materials such as: machine head material, chemical blue barrels, etc., if the processing of raw materials is smaller and lower hardness can be directly adopted crusher.

 

3. Plastic Crusher


Processing plastic into smaller sheets (10mm~14), the finished size is determined by using different screen apertures.

 

4. Finished product collection device


The finished products are fed into the cache bin through the wind conveying system.

 

5. Metal Detectors

The metal detector can replace manual re-selection, when metal is detected, the metal detector will sound an alarm and stop the conveyor temporarily, reducing wear and tear of the crusher blades and reducing the sharpening cycle.
