Zig-Zag air separator (pneumatic separator) is designed for simultaneous dedusting and dry separation of materials into light and heavy fractions by size, density and shape with up to 99% efficiency.

  • Closed air circuit: no filters and compact footprint

The machine is designed as a mini-plant (Zig-Zag separator, cyclone and fan) with closed air circuit: air purified from the product leaves the cyclone and enters the fan, from where it enters Zig-Zag separator, forming closed air cycle. As a result, the separator works without filters and has smaller footprint*.

* unlike open-circuit air separators

  • Dry separation method: pure economy!

Zig-Zag air separator allows for replacement or supplement existing equipment, improving the quality of feed material with less power consumption and no time and money spent on water and drying**.

** comparing to wet separation method

  • Separation/cleaning efficiency up to 99%

Separation mode is selected depending on material and requirements to end product. Optimum selection of the working chamber of the Zig-Zag separator and air flow parameters allow for 99% separation efficiency and purity of feed material.

  • Easy operation

Easy to operate, without quick-wear mechanisms and vibration loads, Zig-Zag air separator works continuously not requiring special attention from personnel.

  • Application industries

Recycling:

- PET: label removal, paper from PET flakes;

- Shredded cable: separation of copper and aluminum from PE/PVC insulation;

- MSW (municipal solid waste): heavy fraction separation (stones, glass, metal, etc.); light fraction separation (film, paper, fabric);

- Glass cullet: glass cleaning from light fraction (film, label removal, dust);

- Tire granulate: separation of textile, dust, rubber granulate;

- WEEE (Waste of electronic and electrical equipment): recovery of plastic, rubber, fabric;

- Wood chips: removal of paper, textile, fabric; recovery of metal, stones, glass;

- Plastic granulate: removal of dust, fluff, fine particles;

- RDF/SRF fuel: separation of light fraction from waste.

Food industry:

- Grain: separation of mineral impurities from processed raw materials, separation of leaf from stem, husk from whole seeds;

- Sugar, table salt, flour and grain, starch, dairy products, tea, gelatin, vegetables, cocoa powder and chocolate chips: removal of residues of polypropylene bags, sack stitching threads, dust;

- Spices, herbs and plants (pharmacy): removal of dust, threads.

Mining, construction and demolition, metallurgy:

- Removal of dusty fraction (dolomite, feldspar, marble chips, etc.), separation by shape (mica, vermiculite, etc.) or specific gravity (chromite ore, metal ceramics, powder metallurgy).

* Depends on material and output fractions
You can additionally order spare parts kit to ensure continuous operation of the equipment:
  • lining
  • spare plates for batch hopper
  • bearing assemblies
For this type of equipment there is an option of integrating REMOS remote monitoring system, providing monitoring of the separator status in real time. Available options:
  • Access to complete information about operation of the machine (operation / idle, operating modes, error decoding, position of magnetic rods, cleaning period)
  • Dust sensor (cyclone operation efficiency control)
  • Power supply sensor
  • Air flow rate sensor
  • Monitoring operation of electric motors (in case of variable speed drive)
  • Incoming switch and contactors position control sensor
  • Equipment downtime monitoring
  • Door status control (open / closed)
  • Shock / vibration sensor
  • Humidity sensor
  • Temperature sensor
