Fig. 2 shows the measured cumulative distribution q 3 (x) of the used protein powder, the starch powder and the protein-starch mixture. All particle sizes are in the same order of magnitude between 0.1 and 30 µm. The comminuted protein and starch particles are smaller than 20 µm and 30 µm, respectively.The particle size distribution of the protein-starch mixture (15 wt% protein) is located ...

Figure 1: ST Equipment & Technology's Triboelectric Belt Separator. The principles of operation of the STET separator are illustrated in Figures 2 & 3. The particles are charged by the triboelectric effect through particle-to-particle collisions in the air slide feed distributor and …

The triboelectric particle charging is effective for a wide range of materials and only requires particle-particle contact. The small gap, high electric field, counter-current flow, vigorous particle-particle agitation and self-cleaning action of the belt on the electrodes are the critical features of the ST separator.

This triboelectric plastic separator was constructed at Vietnamese German University.

Negative air ions (NAIs), known as 'air vitamins', are small ions with an average electric mobility of 1–2 cm 2 V −1 s −1.They are widely used for indoor air purification, including the ...

analyze performance of triboelectric separators for sorting different types of insulating particles. There are currently several methods of triboelectric charging using rotating tubes [20-22], fluidized beds [23-28], a vibrating feeder [29-30], tribo-cyclones [31-32], fans [33-34], static charger, a honeycomb and a spiral tube charger.

The two-conveyor-electrodes tribo -Aero-electrostatic separator patented in 2010 was designed to sort granular mixtures of insulating materials in a fluidized bed subjected to an electric field ...

triboelectric effect can be depicted with as [4, 16] CS k /4π (1) where C is the equivalent capacitance, is the material's dielectric constant, and k is the electrostatic constant. The simplest configuration with the capaci-tance in the triboelectric interface is shown in Fig. 1.

2. Design and build a prototype triboelectric separator machine for a heterogenous HPDE/paper flake mixture based on the results of the proof of concept and utilizing the recommendations of the Sumner [19] study. 3. Conduct a set of experiments to prove or disprove the efficacy of the prototype separator machine and determine the most effective

Schematic of triboelectric belt separator . The separator design is relatively simple. The belt and associated rollers are the only moving parts. The electrodes are stationary and composed of an appropriately durable material. The belt is made of plastic material. The separator electrode length is approximately 6 meters (20 ft.) and the width 1 ...

Triboelectrostatic separator. Triboelectrostatic separation is one of the advanced techniques for separation of plastic materials. This technique is based on the triboelectric effect. It is known that when electrically non-conducting particles of two different levels come into contact with electric charge, one of them becomes more positive (or ...
